• Terminal Server 2008: Remote App Issue

  - by JohnyD

  I have a FoxPro 2.6 (16-bit) application that I've installed on a Win2008 (32-bit) Terminal Server. I then created a Remote App from it. It works fine. The problem is that within this FoxPro application it calls out to a .Net application. I have the proper .Net Framework installed on the server (2.0) and I have run the code access security policy tool (caspol.exe). However, when I launch the .Net app from within the FoxPro application I get the following error: Description: Stopped working Problem signature: Problem Event Name: CLR20r3 Problem Signature 01: vector.exe Problem Signature 02: 1.0.0.3 Problem Signature 03: 48b579f2 Problem Signature 04: vector Problem Signature 05: 1.0.0.3 Problem Signature 06: 48b579f2 Problem Signature 07: f Problem Signature 08: 57 Problem Signature 09: System.Security.Security OS Version: 6.0.6001.2.1.0.18.10 Locale ID: 1033 Vector.exe is our .Net application. In fact, it's an in-between application that checks to ensure you have the latest version. When it's done it calls out to another .Net executable. Does anyone believe this should be a problem? Thanks in advance.

• IIS permission configuration issue

  - by Dan

  Sorry the title of this question is a little ambiguous but I don't really have any idea where the issue lies - I'm seeking some clarification of the server error logs. Basically, I had a dedicated server running Windows 2003 and Plesk (v8 I think). Last week the server hardware failed and the entire thing had to be rebuilt from scratch. New hardware was put in, new operating system (Win2008), new Plesk installation (v9.5), new software (MSSQL etc) then all data ported over manually from old C and D drives to restore all 30 client sites. It was hell! All has been okay for a couple of days now but about an hour ago POP! Suddenly all sites went down giving a 500 error. Restarting all services eventually brought everything back online, but I'm now living in total fear. It can - and probably will - happen again. The guys on support gave me the following errors from the server log: The Template Persistent Cache initialization failed for Application Pool 'ASP.NET v4.0 Classic' because of the following error: Could not create a Disk Cache Sub-directory for the Application Pool. The data may have additional error codes.. The worker process for application pool 'domain1.com(domain)(2.0)(pool)' encountered an error 'Cannot read configuration file ' trying to read configuration data from file '\\?\C:\inetpub\temp\apppools\domain1.com(domain)(2.0)(pool).config', line number '0'. The data field contains the error code. The worker process for application pool 'PleskControlPanel' encountered an error 'Cannot read configuration file ' trying to read configuration data from file '\\?\C:\inetpub\temp\apppools\PleskControlPanel.config', line number '0'. The data field contains the error code. The support guys are so ambiguous about this and it scares me horribly. Can anyone positively identify the cause of this error which lead to all client website going offline? What can be done to prevent it from happening again? Any pointers would be very much appreciated! Thanks folks...

• IIS6 Virtual SMTP server isn't coming back up automatically after a system restart

  - by Julian James

  I've got a virtual server running Win2008 RC2. I've set up IIS6 with a virtual SMTP server on it to be the mail provider for the websites I'm hosting there. It all works great, but if for some reason the server reboots (auto updates are still enabled - I'm trying to make this as little work as possible as we've got a Lot of clients), the IIS6 doesn't restart the SMTP server. The failure causes 500 errors on the current setup, so I'm spending half the day apologising. Any ideas? In Services I've set everything to come back up automatically, but still no dice. As soon as I restart the SMTP, no problems, all the mail gets sent. It's working perfectly, it just won't restart on it's own. I'd really rather not turn auto updates off as we're such a small company I just can't spare the time to be manually updating 15 copies of windows every time MS decide there's a security patch. All advice appreciated! BTW, I am a complete newb to these forums. I searched but couldn't find an answer, so please be nice. But firm. I've got to learn here.

• LDAP, Active Directory and bears, oh my!

  - by Tim Post

  What I have: Workstations running Ubuntu Jaunty mounting /home on a remote NFS server. User accounts are still created locally on each individual workstation. Workstations running Windows XP / Vista NFS server (as noted above) Windows 2008 server All machines share a single private network (LAN). What I need to accomplish: A single, intuitive (GUI driven) place for an office administrator to create user accounts. This should let anyone login to their (linux or windows) workstation, then fire up remote desktop and use the same login to the Windows 2008 server, from any machine on the network. I have read so much on samba, LDAP vs AD, etc and now I'm even more confused than I was before I began researching the problem. Ideally, Linux and Windows users should be able to get to their local files once logged into the Win2008 server. I am a programmer, not an interoperability guru and I'm completely lost on where to even start trying to accomplish this, plus I've run out of things to Google. How would you do this? Is it even possible?

• On what should i not be pennywise buying a machine for SqlServer 2008?

  - by Michel

  Hi, i'm going to do a project for a client and i'll be hosting the database server myself. Normally it would be on my dev machine, but there will also be data pushed into it during developing and testing, so i would like to setup a dedicated test sql server. But, as you might guess, i can't afford to go to Dell and buy one mega 16 core 16 GIG 10 TB raid 5 machine (wow, that sounds cool) So i have to save the money somewhere... the hardware only has to live for a year (longer is nice of course), and the sql server won't be hit too hard: i guess the average server will only see it as a cough once in a while. But i do want the machine to be a bit performant: if it does get some data, it must be a bit responsive. So my question is were can i leave out the expensive parts: is 2 GB enough, or must i take 4GB, is an average processor enough or should it be a top of the bill? Is Sql server a large resource user or is a simple desktop pc good enough? It wil run on win2008 by the way.

• Apache stops responding to http requests -- https continues to work

  - by Apropos

  Okay. Very strange problem that I'm having here. I just recently updated to Apache 2.4.2 from 2.2.17, mostly to try to get name-based SSL VirtualHosts working (although they should have been working on 2.2.17). Server is Win2008 R2 (so x64 by definition) running with PHP 5.4.3 and MySQL 5.1.40 (outdated, I know). When I launch the server, it initially works fine. Responds to all requests, VirtualHosts all in order. However, after an uncertain amount of time (appears to only take a few minutes for the most part, but sometimes takes hours), it stops responding to regular HTTP requests (on any VirtualHost). HTTPS continues to work. No errors in the log, and nothing in the access logs when I attempt to connect. I'm having a hard time finding the source of this error given its intermittent nature. When removing all SSL-based VirtualHosts, it seemingly increased stability (still responding to HTTP requests twelve hours later). This could be mere coincidence, though. Entirety of SSL VirtualHost is as follows, should there happen to be a problem with it. <VirtualHost *:443> DocumentRoot "C:\Server\www\virtualhosts\mysite.net" ErrorLog logs/ssl.mysite.net-error_log CustomLog logs/ssl.mysite.net-access_log common env=!dontlog SSLEngine on SSLProtocol all -SSLv2 SSLCipherSuite ALL:!ADH:!EXPORT:!SSLv2:RC4+RSA:+HIGH:+MEDIUM SSLCertificateFile C:/Server/bin/apache/apache2.4.2/conf/ssl/server.crt SSLCertificateKeyFile C:/Server/bin/apache/apache2.4.2/conf/ssl/server.key SSLCertificateChainFile C:/Server/bin/apache/Apache2.4.2/conf/ssl/sub.class1.server.ca.pem SSLCACertificateFile C:/Server/bin/apache/Apache2.4.2/conf/ssl/ca.pem </VirtualHost> Any ideas what I'm missing?

• Virtual Windows 2008 Server Activation with ESX

  - by Logman

  I had a decommissioned server (Dell PE2950) that we could still use, it had OEM Windows 2003 Std on it but wanted to use it as a new host with VMware ESX5 to put a couple legacy severs on it. I wiped it clean and maxed out the memory. But when I added the memory I noticed the product key sticker was a "WindowsServer08 Std 1-4cpu" product key, and it also had a Virtual Key. Not sure why it had Win2003 and not Win2008 from the start, but I would like to use that license if I can. The virtual host would stay on the same physical server, so there shouldn't be a problem with licensing... but I do not want to use Hyper-V unless I can not help it. I have installed ESX5 on the server, but I cannot get the Windows 2008 server to activate. The product key is hard to read, and I have checked the key quite a few times. But my question is... Is it because Hyper-V was not installed on the host? But I thought you could use the product key alone on a virtual host? Maybe because I am not using a Dell Windows 2008 disk but iso from MS directly via the Volumne Licensing site? EDIT: well, Im pretty sure I got the product key correct. If its not the product key, could the activation problem be because Im not using hyper-v or maybe the correct install dvd? EDIT2: maybe because I added 28GB of memory? Originally 4GB...

• Running batch file through a service.

  - by wallz

  I'm trying to schedule a batch file to run through a third party application, however the output file doesn't get created in the directory. If I run the .BAT file from the command line, it works and the file gets created. Also using the Windows Schedule will also succeed. Basically, the 3rd party software will schedule the .BAT file and it shows success within the 3rd party user interface. The difference between running from the command prompt and the software, is that the software will use its Windows service to launch the batch. The 3rd party software will show success since it was able to successfully call the .BAT file to run, however it has no control of the other EXE's that's being called within the script. I'm able to run a simple .BAT file in the 3rd party software, for example a copy command. The .BAT I'm having problems with calls a compiled EXE which launches Excel to create a file to a location. The .bat file calls something.exe, which then calls Excel.exe: C:\something.exe -o D:\filename.xlsm C:\filename.xlsm refresh_pivot Do you think it's a permissions issue? I used Process Monitor to verify any Access Denied errors but everything seems to be working according to the trace. It worked on a non-64-bit OS, I'm currently using Win2008 64-bit.

• Hyper-V VM's cannot access Host resources, and vice-versa

  - by Agent

  I have several Hyper-V vm's running on this Win2008 R2 Server box, and up until a reboot of the host server, all the VM's were able to access shared folders on the host. Now, they can't even ping the host server. From what I've seen, I need to setup an Internal only network through Virtual Network Manager in Hyper-V. I set this up, then tried to enable the Microsoft Virtual Network Switch Protocol option in this Internal Only NIC, but I get popups saying: Your current selection will also disable the following features: Microsoft virtual network switch protocol Which is absolutely stupid, considering the protocol is what I'm ticking the checkbox to Enable! As of now, on the host, I have 2 NICs: Physical - This NIC on the host machine does have the MVNS protocol enabled Virtual Network Adapter - Created through Hyper-V Virtual Network Manager as an External type of network. Trying to enable MVNS on this NIC also produces the error above. I've tried enabling Client for Microsoft Networks on the physical NIC for IPv6, but everytime I do that, all the VMs lose Internet connectivity and I cannot RDP into them. Anything else I can try?

• File corruption (bad checksums) in large files copied to VMware guest

  - by AllanA

  In setting up a development lab, I've got a desktop system running ESXi 4.1.0 (free license) on SATA RAID 0 (already purchased and configured when I started this job; I'm open to hardware input as it pertains to my problem.) Its guests so far include two Win2008 Server R2 64-bit VMs and on Ubuntu 10.04 64-bit VM. I'm installing onto the Windows servers. We've been copying off some fairly large files (over a gigabyte) for an installation, hoping to install more quickly from a (virtual) hard drive than from the network for from BD-ROM. The problem is that they keep coming up with different checksums from the originals. The file sizes are the same, but md5sum reports different numbers (and so does the installer, as it refuses to continue when the checksums don't match.) I've tried copying directly from the BD-ROM (attaching the OS drive to the host system's physical drive). I've tried copying the large files onto a co-worker's Windows machine from his Blu-Ray drive; when I do that, the checksums match. But when I copy from his machine to the VM guest over a network share, the checksums no longer match. Thinking this meant a corrupt destination drive, I deleted it in vSphere and added another freshly created drive. The problem persists. I'm not sure what to try next.

• Install KVM based Windows 2008 remotely over SSH on a headless, no graphics Ubuntu 10.04 server?

  - by taazaa

  Hi, I have a Dell server at a remote data center with Ubuntu 10.04 as the host. It is a minimal install with the necessary virtulization packages. There is no X and the machine is headless. I have the win2008 DVD in the machine and want to remotely install it. I tried: virt-install --connect qemu:///system -n vmwin2k8 -r 1024 --disk path=server2k8.qcow2,size=50 --cdrom /dev/sr0 --vnc --noautoconsole --os-type windows --os-variant win2k8 The qcow2 image get created However I don't understand how to connect to see the install via VNC. This is my first time doing it so it may be trivial or may not be possible. Remotely I have a Win 7 machine with Putty and RealVNC viewer. Where is the graphic output of VNC going? Do I have to have VNC server running on the host or some other machine and then connect to it from my VNC client? Please let me know or point me to the right direction. I have been searching the web for several days to figure out how this is suppose to work. Thanks!

• "SignTool error: Access is denied" in TFS 2010 build process

  - by user351352

  I'm getting "SignTool Error: Access is Denied" when I attempt to sign a file. When I use an administrator cmd, all works fine. However, this process is going to be used in a TFS 2010 build process and using the InvokeProcess task with signtool gives the same access denied message as a non-administrator command prompt. More info: On a Win2008 R2 enterprise machine. User is machine admin and on the domain. The TFS Build service is also set to run as this user. Using a self signed certificate created using these instructions: How do I create a self-signed certificate for code signing on Windows? After following these instructions I have the following files: MyCA.cer MyCA.pvk MySPC.cer MySPC.pvk MySPC.pfx MyCA is in my Trusted Root Certification Authorities I imported MySPC.pfx into personal certificates, following the advice here: SignTool error: Access is denied To do the signing I'm using the thumbprint of the MySPC.pfx that was imported into the Personal section so my signtool command looks like: sign /sha1 1e9d7b5ad98552d9c58944e3f3903e6b929f4819 /t http://timestamp.verisign.com/scripts/timestamp.dll "FileName" Once again this works in Admin mode. This also works when running cmd as administrator: sign /f "C:\Code Signing Non-Release\MySPC.pfx" /t http://timestamp.verisign.com/scripts/timestamp.dll "FileName" New to code signing in general, so any help is welcome.

• Printer Redirection from 2003 Terminal Server to 2008 Terminal Server

  - by xmaveric

  Our environment is a terminal server cluster (Win2003 servers) that everyone connects to do do their work. I have set up a new Win2008 R2 machine with the intention of using it to publish our main application to the TS farm. The idea was to keep this server dedicated to one application to avoid driver/dll conflicts with other software. I created a RemoteApp on the new server and made an .rdp file and placed it on the desktop of our TS farm servers. The problem I am running into is that when I connect to the RemoteApp, it doesn't show the printers that are installed on the TS server I am connecting from. We have over 20 printers installed on our TS servers, each with different drivers and permissions. I really do not want to reinstall all of these on the RemoteApp server so I was hoping Printer Redirection would handle this. It would appear that because the RDP client for Server 2003 x64 is 6.0, that version doesn't support the Easy Print feature (requires 6.1). I can't find any newer version on the MS site to download for Win2003 x64. How can I get the printers on the TS farm machine to redirect so they are viewed by the RemoteApp machine?

• Internet Explorer 8 timeout too quick on page POSTs

  - by cdm9002

  We have an asp.net site running, which has been working fine for some time, but recently I have been experiencing some issues with IE8. On posting some pages - mainly on our development server, although on staging too - we get an occasional "Internet Explore cannot display the webpage" error along with the button asking to diagnose connection problems. IE only seems to wait 10 seconds before timing out. I know that the page itself may take longer to load the first time (on dev and staging). So press F5 and everything then works fine. Is there anything that should be done in the aspx page to tell IE to wait a bit longer? I thought I had read that the default timeout supposed to be 90 seconds or something for browsers. A bit more info: It mostly happens on a POSTing a signup page, but that is just because I test that page and it starts the IIS App, makes the first connection to SQL and pre-caches some information. That first time the page can take 10-15 seconds to come back. IE8 times out after 10 seconds as it has had nothing back. This happens on a dev W7x64 machine with 8GB RAM, as well as on a staging server WIN2008. Having googled around a bit, some people are seeing the same problem, but no conclusive pointers to the problem or a solution. It isn't a connection problem; everything works fine in Firefox, Chrome and even IE7; I have tried with add-ons disabled and resetting IE settings, still happens. Ideas welcome.

• Creating a dynamic lacp trunk from HP Procurve 2412zl to Proliant DL380 G7

  - by Maalobs

  I'm configuring an IEEE 802.3ad (LACP) dynamic trunk from a HP Procurve 2412zl (firmware version K.15.07) switch to a HP Proliant DL380 G7 server. The DL380 has 4 NICs and is running Win2008 R2, so I'm teaming the NICs together and leaving everything on the recommended "automatic" setting in the HP NIC configuration tool. The server is one of two, they'll be connected on interfaces F17-F20 and F21-F24 respectively on the switch. I need the servers in a separate VLAN, here is the configuration for the VLAN: vlan 10 name "Lab_Mgmt" untagged B2,F17-F24 ip address 172.22.71.3 255.255.255.0 tagged B21 exit There is a DHCP-relay into the VLAN 10 from another device beyond interface B21. The Advanced Traffic Management Guide says that in order to run a dynamic LACP trunk on another VLAN besides the DEFAULT_VLAN, you need to first enable GVRP and then use "forbid" to stop the interfaces from automatically joining DEFAULT_VLAN when the dynamic trunk is created. GVRP brings some other stuff with it that I don't want or need, so I disable it with "unknown-vlans disable" on all other interfaces. Here is how I do it: procurve-5412zl-1(config)# gvrp procurve-5412zl-1(config)# interface A1-A24,B1-B24,C1-C24,D1-D10,D13-D24,E1-E24, F1-F16,K1,K2 unknown-vlans disable procurve-5412zl-1(config)# vlan 1 forbid F17-F24 procurve-5412zl-1(config)# interface F17-F20 lacp active The result afterwards looks all successful: procurve-5412zl-1(config)# show trunks Load Balancing Method: L3-based (Default), L2-based if non-IP traffic Port | Name Type | Group Type ---- + -------------------------------- --------- + ------ -------- F17 | XYZTEAM3_NIC1 100/1000T | Dyn2 LACP F18 | XYZTEAM3_NIC2 100/1000T | Dyn2 LACP F19 | XYZTEAM3_NIC3 100/1000T | Dyn2 LACP F20 | XYZTEAM3_NIC4 100/1000T | Dyn2 LACP procurve-5412zl-1(config)# vlan 10 procurve-5412zl-1(vlan-10)# show lacp LACP LACP Trunk Port LACP Admin Oper Port Enabled Group Status Partner Status Key Key ---- ------- ------- ------- ------- ------- ------ ------ F17 Active Dyn2 Up Yes Success 0 0 F18 Active Dyn2 Up Yes Success 0 0 F19 Active Dyn2 Up Yes Success 0 0 F20 Active Dyn2 Up Yes Success 0 0 On the Proliant server, the NIC configuration Tool is also indicating that a 802.3ad dynamic trunk has been established. Everything should be good, but it isn't. The server is not getting an IP-address from the DHCP, which it does if I'm not enabling LACP. If I configure the server to a static IP-address on the VLAN 10 subnet, it can't even ping the switch IP-address, much less anything outside of the VLAN. The switch can't ping the server either. I did another attempt with F17-F20 tagged, and checking the box "Default Native Tag (VLAN 10)" in the NIC configuration tool on the server, but there was no difference. Does anyone have any idea what I might have missed?

• Certain clients (IP range) can not ping server

  - by Logman

  I just virtualized a Windows 2003 Server SP2 x32. The server contained our help desk server (Spiceworks) and our anti virus management server (ESET RAC). The host computer actually contained the virtualized server originally; I created the vhd and then I wiped this system clean and installed Windows 2008 R2 x64 Datacenter and added the virtualized 2003 onto the Hyper-V 2008 R2 Server. I got the server running fine except for... certain ip ranges. Local clients can get updates from the AV server from my 192.168.180.xxx & 192.168.181.xxx BUT NOT from any 192.168.182.xxx, 192.168.183.xxx, 192.168.184.xxx etc... I can not ping the server from any clients except for the 180. & 181. ranges. Now I created 2 other virtualized servers (win2008 & a win7 pro) and they exist on the same virtual host as the 2003 server. And at first I could not ping those until I went to the "\Network and Sharing Center\Advanced sharing settings" and Turned On File and Print Sharing. Then I could ping and access those virtualized guests. Win2003 server isn't quite the same. But I am sure I have it on. But now when I ping from a client on one of those ranges that would not work I get this: As you can see the ping leaves our network. We have 2 ad/dns servers (one 180. & the other in the 181. range). Is it DNS? Both AD/DNS servers are Windows 2003. And we plan on upgrading both to 2008 R2 within a month or two but I need to fix this issue pronto (esp the AV end). btw, I did rename that 2003 Server (Spiceworks/AV) hostname. And I tried a CNAME. But I do not think that is the problem. EDIT: OR because this server existed on this hardware/computer before becoming virtualized?

• recommendations for efficient offsite remote backup solution of vm's

  - by senorsmile

  I am looking for recommendations for backing up my current 6 vm's(and soon to grow to up to 20). Currently I am running a two node proxmox cluster(which is a debian base using kvm for virtualization with a custom web front end to administer). I have two nearly identical boxes with amd phenom II x4's and asus motherboards. Each has 4 500 GB sata2 hdd's, 1 for the os and other data for the proxmox install, and 3 using mdadm+drbd+lvm to share the 1.5 TB's of storage between the two machines. I mount lvm images to kvm for all of the virtual machines. I currently have the ability to do live transfer from one machine to the other, typically within seconds(it takes about 2 minutes on the largest vm running win2008 with m$ sql server). I am using proxmox's built-in vzdump utility to take snapshots of the vm's and store those on an external harddrive on the network. I then have jungledisk service (using rackspace) to sync the vzdump folder for remote offsite backup. This is all fine and dandy, but it's not very scalable. For one, the backups themselves can take up to a few hours every night. With jungledisk's block level incremental transfers, the sync only transfers a small portion of the data offsite, but that still takes at least a half an hour. The much better solution would of course be something that allows me to instantly take the difference of two time points (say what was written from 6am to 7am), zip it, then send that difference file to the backup server which would instantly transfer to the remote storage on rackspace. I have looked a little into zfs and it's ability to do send/receive. That coupled with a pipe of the data in bzip or something would seem perfect. However, it seems that implementing a nexenta server with zfs would essentially require at least one or two more dedicated storage servers to serve iSCSI block volumes (via zvol's???) to the proxmox servers. I would prefer to keep the setup as minimal as possible (i.e. NOT having separate storage servers) if at all possible. I have also briefly read about zumastor. It looks like it could also do what I want, but it appears to have halted development in 2008. So, zfs, zumastor or other?

• Figuring out the IIS Version for a given OS in .NET Code

  - by Rick Strahl

  Here's an odd requirement: I need to figure out what version of IIS is available on a given machine in order to take specific configuration actions when installing an IIS based application. I build several configuration tools for application configuration and installation and depending on which version of IIS is available on IIS different configuration paths are taken. For example, when dealing with XP machine you can't set up an Application Pool for an application because XP (IIS 5.1) didn't support Application pools. Configuring 32 and 64 bit settings are easy in IIS 7 but this didn't work in prior versions and so on. Along the same lines I saw a question on the AspInsiders list today, regarding a similar issue where somebody needed to know the IIS version as part of an ASP.NET application prior to when the Request object is available. So it's useful to know which version of IIS you can possibly expect. This should be easy right? But it turns there's no real easy way to detect IIS on a machine. There's no registry key that gives you the full version number - you can detect installation but not which version is installed. The easiest way: Request.ServerVariables["SERVER_SOFTWARE"] The easiest way to determine IIS version number is if you are already running inside of ASP.NET and you are inside of an ASP.NET request. You can look at Request.ServerVariables["SERVER_SOFTWARE"] to get a string like Microsoft-IIS/7.5 returned to you. It's a cinch to parse this to retrieve the version number. This works in the limited scenario where you need to know the version number inside of a running ASP.NET application. Unfortunately this is not a likely use case, since most times when you need to know a specific version of IIS when you are configuring or installing your application. The messy way: Match Windows OS Versions to IIS Versions Since Version 5.x of IIS versions of IIS have always been tied very closely to the Operating System. Meaning the only way to get a specific version of IIS was through the OS - you couldn't install another version of IIS on the given OS. Microsoft has a page that describes the OS version to IIS version relationship here: http://support.microsoft.com/kb/224609 In .NET you can then sniff the OS version and based on that return the IIS version. The following is a small utility function that accomplishes the task of returning an IIS version number for a given OS: /// <summary> /// Returns the IIS version for the given Operating System. /// Note this routine doesn't check to see if IIS is installed /// it just returns the version of IIS that should run on the OS. /// /// Returns the value from Request.ServerVariables["Server_Software"] /// if available. Otherwise uses OS sniffing to determine OS version /// and returns IIS version instead. /// </summary> /// <returns>version number or -1 </returns> public static decimal GetIisVersion() { // if running inside of IIS parse the SERVER_SOFTWARE key // This would be most reliable if (HttpContext.Current != null && HttpContext.Current.Request != null) { string os = HttpContext.Current.Request.ServerVariables["SERVER_SOFTWARE"]; if (!string.IsNullOrEmpty(os)) { //Microsoft-IIS/7.5 int dash = os.LastIndexOf("/"); if (dash > 0) { decimal iisVer = 0M; if (Decimal.TryParse(os.Substring(dash + 1), out iisVer)) return iisVer; } } } decimal osVer = (decimal) Environment.OSVersion.Version.Major + ((decimal) Environment.OSVersion.Version.MajorRevision / 10); // Windows 7 and Win2008 R2 if (osVer == 6.1M) return 7.5M; // Windows Vista and Windows 2008 else if (osVer == 6.0M) return 7.0M; // Windows 2003 and XP 64 bit else if (osVer == 5.2M) return 6.0M; // Windows XP else if (osVer == 5.1M) return 5.1M; // Windows 2000 else if (osVer == 5.0M) return 5.0M; // error result return -1M; } } Talk about a brute force apporach, but it works. This code goes only back to IIS 5 - anything before that is not something you possibly would want to have running. :-) Note that this is updated through Windows 7/Windows Server 2008 R2. Later versions will need to be added as needed.

• Deploying MVC2 application to IIS7.5 - Ninject asked to provide controllers for content files

  - by Rune Jacobsen

  I have an application that started life as an MVC (1.0) app in Visual Studio 2008 Sp1 with a bunch of Silverlight 3 projects as part of the site. Nothing fancy at all. Using Ninject for dependency injection (first version 2 beta, now the released version 2 with the MVC extensions). With the release of .Net 4.0, VS2010, MVC2 etc., we decided to move the application to the newest platform. The conversion wizard in VS2010 apparently took care of everything, with one exception - it didn't change references to mvc1 to now point to mvc2, so I had to do that manually. Of course, this makes me think about other MVC2 things that could be missing from my app, that would be there if I did File - New Project... But that is not the focus of this question. When I deploy this application to the IIS 7.5 server (running on Win2008 R2 x64), the application as such works. However, images, scripts and other static content doesn't seem to exist. Of course they are there on disk on the server, but they don't show up in the client web browser. I am fairly new to IIS, so the only trick I knew is to try to open the web page in a browser on the server, as that could give me more information. And here, finally, we meet our enemy. If I try to go directly to the URL of one of the images (http://server/Content/someimage.jpg for instance), I get the following error in the browser: The IControllerFactory 'Ninject.Web.Mvc.NinjectControllerFactory' did not return a controller for a controller named 'Content'. Aha. The web server tries to feed this request to MVC, who with its' default routing setup assumes Content to be a controller, and fails. How can I get it to treat Content/ and Scripts/ (among others) as non-controllers and just pass through the static content? This of course works with Cassini on my developer machine, but as soon as I deploy, this problem hits. I am using the last version of Ninject MVC 2 where the IoC tool should pass missing controllers to the base controller factory, but this has apparently not helped. I have also tried to add ignore routes for Content etc., but this apparently has no effect either. I am not even sure I am addressing the problem on the right level. Does anyone know where to look to get this app going? I have full control of the web server so I can more or less do whatever I want to it, as long as it starts working. Thanks!

• NetApp erroring with: STATUS_NOLOGON_WORKSTATION_TRUST_ACCOUNT

  - by Sobrique

  Since a sitewide upgrade to Windows 7 on desktop, I've started having a problem with virus checking. Specifically - when doing a rename operation on a (filer hosted) CIFS share. The virus checker seems to be triggering a set of messages on the filer: [filerB: auth.trace.authenticateUser.loginTraceIP:info]: AUTH: Login attempt by user server-wk8-r2$ of domain MYDOMAIN from client machine 10.1.1.20 (server-wk8-r2). [filerB: auth.dc.trace.DCConnection.statusMsg:info]: AUTH: TraceDC- attempting authentication with domain controller \\MYDC. [filerB: auth.trace.authenticateUser.loginRejected:info]: AUTH: Login attempt by user rejected by the domain controller with error 0xc0000199: STATUS_NOLOGON_WORKSTATION_TRUST_ACCOUNT. [filerB: auth.trace.authenticateUser.loginTraceMsg:info]: AUTH: Delaying the response by 5 seconds due to continuous failed login attempts by user server-wk8-r2$ of domain MYDOMAIN from client machine 10.1.1.20. This seems to specifically trigger on a rename so what we think is going on is the virus checker is seeing a 'new' file, and trying to do an on-access scan. The virus checker - previously running as LocalSystem and thus sending null as it's authentication request is now looking rather like a DOS attack, and causing the filer to temporarily black list. This 5s lock out each 'access attempt' is a minor nuisance most of the time, and really quite significant for some operations - e.g. large file transfers, where every file takes 5s Having done some digging, this seems to be related to NLTM authentication: Symptoms Error message: System error 1808 has occurred. The account used is a computer account. Use your global user account or local user account to access this server. A packet trace of the failure will show the error as: STATUS_NOLOGON_WORKSTATION_TRUST_ACCOUNT (0xC0000199) Cause Microsoft has changed the functionality of how a Local System account identifies itself during NTLM authentication. This only impacts NTLM authentication. It does not impact Kerberos Authentication. Solution On the host, please set the following group policy entry and reboot the host. Network Security: Allow Local System to use computer identity for NTLM: Disabled Defining this group policy makes Windows Server 2008 R2 and Windows 7 function like Windows Server 2008 SP1. So we've now got a couple of workaround which aren't particularly nice - one is to change this security option. One is to disable virus checking, or otherwise exempt part of the infrastructure. And here's where I come to my request for assistance from ServerFault - what is the best way forwards? I lack Windows experience to be sure of what I'm seeing. I'm not entirely sure why NTLM is part of this picture in the first place - I thought we were using Kerberos authentication. I'm not sure how to start diagnosing or troubleshooting this. (We are going cross domain - workstation machine accounts are in a separate AD and DNS domain to my filer. Normal user authentication works fine however.) And failing that, can anyone suggest other lines of enquiry? I'd like to avoid a site wide security option change, or if I do go that way I'll need to be able to supply detailed reasoning. Likewise - disabling virus checking works as a short term workaround, and applying exclusions may help... but I'd rather not, and don't think that solves the underlying problem. EDIT: Filers in AD ldap have SPNs for: nfs/host.fully.qualified.domain nfs/host HOST/host.fully.qualified.domain HOST/host (Sorry, have to obfuscate those). Could it be that without a 'cifs/host.fully.qualified.domain' it's not going to work? (or some other SPN? ) Edit: As part of the searching I've been doing I've found: http://itwanderer.wordpress.com/2011/04/14/tread-lightly-kerberos-encryption-types/ Which suggests that several encryption types were disabled by default in Win7/2008R2. This might be pertinent, as we've definitely had a similar problem with Keberized NFSv4. There is a hidden option which may help some future Keberos users: options nfs.rpcsec.trace on (This hasn't given me anything yet though, so may just be NFS specific). Edit: Further digging has me tracking it back to cross domain authentication. It looks like my Windows 7 workstation (in one domain) is not getting Kerberos tickets for the other domain, in which my NetApp filer is CIFS joined. I've done this separately against a standalone server (Win2003 and Win2008) and didn't get Kerberos tickets for those either. Which means I think Kerberos might be broken, but I've no idea how to troubleshoot further. Edit: A further update: It looks like this may be down Kerberos tickets not being issued cross domain. This then triggers NTLM fallback, which then runs into this problem (since Windows 7). First port of call will be to investigate the Kerberos side of things, but in neither case do we have anything pointing at the Filer being the root cause. As such - as the storage engineer - it's out of my hands. However, if anyone can point me in the direction of troubleshooting Kerberos spanning two Windows AD domains (Kerberos Realms) then that would be appreciated. Options we're going to be considering for resolution: Amend policy option on all workstations via GPO (as above). Talking to AV vendor about the rename triggering scanning. Talking to AV vendor regarding running AV as service account. investigating Kerberos authentication (why it's not working, whether it should be).

• BugZilla XML RPC Interface

  - by Damo

  I am attempting to setup BugZilla to receive but reports from another system using the XML-RPC interface. BugZilla works fine on its own with its own interface. When I attempt to test the XML-RPC functionality by accessing "xmlrpc.cgi" in my browser I get the error: The XML-RPC Interface feature is not available in this Bugzilla at C:\BugZilla\xmlrpc.cgi line 27 main::BEGIN(...) called at C:\BugZilla\xmlrpc.cgi line 29 eval {...} called at C:\BugZilla\xmlrpc.cgi line 29 Following this I install test-taint package from the default perl repository, this installs version 1.04. Re-running "xmlrpc.cgi" gives me an IIS error: 502 - Web server received an invalid response while acting as a gateway or proxy server. There is a problem with the page you are looking for, and it cannot be displayed. When the Web server (while acting as a gateway or proxy) contacted the upstream content server, it received an invalid response from the content server. So I run the checksetup.pl which inform me that: Use of uninitialized value in open at C:/Perl/site/lib/Test/Taint.pm line 334, <DATA> line 558. Installing Test-Taint from CPAN is the same. I assume XML-RPC is relent on Test-Taint, but Test-Taint doesn't seem to run correctly. If I ignore this error and attempt to invoke "bz_webservice_demo.pl" to add an entry the script times out.
