• Sonicwall NSA 240, Configured for LAN and DMZ, X0 and X2 on same switch - ping issues

  - by Klaptrap

  Our Sonicwall vendor supplied and networked the NSA240 when we required a DMZ in our infrastructure. This was configured and appeared correct although VPN users periodically dropped DNS and Terminal Services. The vendor could not resolve and so the call was escalated to Sonicwall. The Sonicwall support engineer took a look and concluded that the X0 (LAN) and X2 (DMZ) intefaces were cabled to the same switch and so this is the issue. What he observed is a ping request to the LAN Domain Controller, from a connected VPN user, is forwarded (x0) from the VPN client IP to the DC IP but the ping response from the DC IP to the VPN client IP is on X2, a copy of the log is detailed below:- 02/02/2011 10:47:49.272 X1*(hc) X0 192.168.1.245 192.168.1.8 IP ICMP -- FORWARDED 02/02/2011 10:47:49.272 -- X0* 192.168.1.245 192.168.1.8 IP ICMP -- FORWARDED 02/02/2011 10:47:49.272 X2*(i) -- 192.168.1.8 192.168.1.245 IP ICMP -- Received X0 - LAN X1 - WAN X2 - DMZ The Sonicwall engineer concluded that we either need a seperate switch for X2 or we use a VLAN switch for both. I am the companies software engineer and we have yet to have heard back from the vendor, so I am lost at sea at the moment. Do we need to buy this additional equipment or is there another configuration on the NSA240 we can use?

• Migrate users from one Active Directory domain to another?

  - by Matt

  I work for a company that hosts desktops for a number of different companies. At the moment, all the clients access a single domain controller called HOSTING. Under that are groups for each company. Each of the hosting servers exist on the same network and so are therefore potentially browseable by other terminal servers. This has raised some security issues and I've found it a little tricky to manage the security. As well, it's possible to see who the other hosted companies are even though other users cannot see their data. What I'd like to do is isolate each clients terminal server/s into their own VLAN. In addition, I'm thinking that each TS would have it's own DC which could just run on the TS for that company. Overhead for a DC is fairly minimal. This would isolate users on that TS from seeing the other companies completely. Firstly, does this sound like a sensible plan? Second... if it is sensible, how would I go about pulling the accounts from the HOSTING domain to a new domain? ideally, without the need for users to change their passwords?

• Windows 7 - system error 5 problem

  - by ianhobson

  My wife has just had a new computer for Christmas (with an upgrade from VISTA to Windows 7), and has joined the home network. We are using a mix of WindowsXP and Ubuntu boxes linked via a switch. We are all in the same workgroup. (No domain). Internet access, DHCP, and DNS server is an SME server that thinks it is domain controller (although we are not using a domain). I need to run a script to back up my wife's machine (venus). In the past the script creates a share on a machine with lots of space (leda), and then executes the line. PSEXEC \\venus -u admin -p adminpassword -c -f d:\Progs\snapshot.exe C: \\leda\Venus\C-drive.SNA With the wife's old XP machine, this would run the sysinternals utility, copy shapshot,exe to her machine and run it, which would then back up her C: drive to the share on leda. I cannot get this to work with Windows 7, nor can I link through to the C$ share on her machine. This gives me a permissions error (system error 5). The admin account is a full admin account. And yes - I do know the password. The ordinary shares on her machine work fine! I guess I'm missing something that Microsoft have built into Windows 7 - but what? The machine is running Windows 7 business, with windows firewall, AVG anti virus, and all the crap-ware you get with a new PC removed. Thanks

• How to set up RAID-0 first time on new PC?

  - by jasondavis

  I have built basic PC's in the past but have never used a RAID array at all. SO now I am buying parts to build my new PC, it will be an intel i7 processor. My motherboard will have RAID support which I will use instead of an aftermarket raid controller for now. Also I plan to use 2 SSD drives in RAID-0 for my windows 7 OS. (Please note that I am aware of the issues with doing this, including lack of TRIM support when using RAID with SSD drives. I am OK with it not working as I can just re[place the drives in a year or so or wheneer they become more sluggish). SO here is my question part. If I assemble the motherboard, PSU, processor, RAM, vidm card, etc and then go to turn the PC on, it will have the 2 SSD drives hooked up. so I assume I will then soon the BIOS screen before I install windows? How to I go about making the 2 drives work in RAID-0 at this point? I do the raid part before installing my OS right? Please help with the steps involved from assembling the parts of the PC and then turning it on, to the part of getting the RAID-0 set up between the 2 drives and then installing my windows 7 OS from a Optical drive? Please help, all advice, instructions, tips appreciated as long as on topic. I do not need to be told that this is a bad idea as far as if 1 drive fails I losse it all, I plan on having a disk IMAGE to be able to restore my OS and software to a new set of drives at anytime needed in the event of drive failure. Same goes for lack of TRIM support. Thanks for reading and help =)

• SBD killing both cluster nodes when there are even small SAN network problems

  - by Wieslaw Herr

  I am having problems with stonith SBD in a openais-based cluster. Some background: The active/passive cluster has two nodes, node1 and node2. They are configured to provide an NFS service to users. To avoid problems with split-brain, they are both configured to use SBD. SBD is using two 1MB disks available to the hosts via an multipath fibre-channel network. The problems start if something happens with the SAN network. For example, today one of the brocade switches got rebooted and both nodes lost 2 out of 4 paths to each disks, which resulted in both nodes committing suicide and rebooting. This, of course, was highly undesirable because a) there were paths left b) even if the switch would be out for 10-20 seconds a reboot cycle of both nodes would take 5-10 minutes and all NFS-locks would be lost. I tried increasing the SBD timeout values (to 10sec+ values, dump attached at the end), however a "WARN: Latency: No liveness for 4 s exceeds threshold of 3 s" hints that something isn't working as I would it expect to. Here is what I would like to know: a) Is SBD working as it should killing nodes when 2 paths are available? b) If not, is the multipath.conf file attached correct? The storage controller we use is an IBM SVC (IBM 2145), should there be any specific configuration for it? (as in multipath.conf.defaults) c) How should I go about increasing the timeouts in SBD attachements: Multipath.conf and sbd dump (http://hpaste.org/69537)

• KVM error with device pass through

  - by javano

  I am running the following command booting a Debian live CD passing a host PCI device to the guest as a test and KVM errors out; kvm -m 512 -boot c -net none -hda /media/AA502592502565F3/debian.iso -device pci-assign,host=07:00.0 PCI region 1 at address 0xf7920000 has size 0x80, which is not a multiple of 4K. You might experience some performance hit due to that. No IOMMU found. Unable to assign device "(null)" kvm: -device pci-assign,host=07:00.0: Device 'pci-assign' could not be initialized lspci | grep 07 07:00.0 Ethernet controller: 3Com Corporation 3c905C-TX/TX-M [Tornado] (rev 74) I shoved an old spare NIC into my motherboard to test PCI pass through. I have searched the Internet with Goolge and found that errors relating to "No IOMMU found" often mean the PCI device is not supported by KVM. Does KVM have to support the device being "passed-through"? I though the point was to pass the device through and let the guest worry about it? Ultimately I want to pass-through a PCI random number generator, is this not going to be possible with KVM? Thank you.

• (manually configured) kernel update leaves wireless in a mess

  - by Mala

  I recently upgraded my kernel from 2.6.31-gentoo-r6 to 2.6.32-gentoo-r7. In both cases, I configured everything manually. However, since the upgrade, my wireless card appears to be on the fritz. It will connect to networks just fine, and remain connected, but can only access the internet (and other hosts on the network) for about 3 seconds after connecting. Reconnecting to the network appears to fix the problem... for another 3 seconds or so. The problem is "solved" by booting into the older kernel. The relevant lspci entry is 02:00.0 Network controller: Intel Corporation PRO/Wireless 5300 AGN [Shiloh] Network Connection I'm pretty sure I have the correct drivers enabled in the kernel Device Drivers ---> Network device support ---> Wireless LAN (IEEE 802.11) ---> <*> Intel Wireless Wifi [*] Enable LED support in iwlagn and iwl3945 drivers [*] Enable Spectrum Measurement in iwlagn driver [*] Enable full debugging output in iwlagn and iwl3945 drivers <*> Intel Wireless WiFi Next Gen AGN (iwlagn) [*] Intel Wireless WiFi 4965AGN [*] Intel Wireless WiFi 5000AGN; Intel WiFi Link 1000, 6000, and 6050 Series I tried with the other intel drivers enabled as well (iwl3945) and no difference. Is there something stupid I'm missing? Is there something I have to recompile after upgrading the kernel (a la nvidia)? Thanks Mala

• Windows authentication to SQL Server via IIS and PHP

  - by Jeff

  We're running a PHP 5.4 application on Server 2008 R2. We would like to connect to a SQL Server 2008 database, on a separate server, using Windows authentication (must be Windows authentication--the DB admins won't let us connect any other way). I have downloaded the SQL Server drivers for PHP and installed them. IIS is configured for Windows authentication, and anonymous authentication has been disabled. $_SERVER['AUTH_USER'] reports our currently logged on Windows account. In php.ini, we have set fastcgi.impersonate = 1. When we setup a connection using the following code from Microsoft: $serverName = "sqlserver\sqlserver"; $connectionInfo = array( "Database"=>"some_db"); /* Connect using Windows Authentication. */ $conn = sqlsrv_connect( $serverName, $connectionInfo); if( $conn === false ) { echo "Unable to connect.</br>"; die( print_r( sqlsrv_errors(), true)); } We are presented with the following error message: Unable to connect. Array ( [0] => Array ( [0] => 28000 [SQLSTATE] => 28000 [1] => 18456 [code] => 18456 [2] => [Microsoft][SQL Server Native Client 11.0][SQL Server]Login failed for user 'NT AUTHORITY\ANONYMOUS LOGON'. [message] => [Microsoft][SQL Server Native Client 11.0][SQL Server]Login failed for user 'NT AUTHORITY\ANONYMOUS LOGON'. ) Is it possible to connect to SQL Server 2008 via PHP using Windows authentication? Are there any additional required settings we need to make on IIS, SQL Server, or any other component (like a domain controller)?

• Virus cleanup + dying drive = XP Automatic Updates crashing in esent.dll

  - by quack quixote

  Background I'm doing system recovery on an old WinXP SP1 system brought to me on suspicion of virus infection. After taking preliminary backups, I used MalwareBytes to detect and clean the infection. I might've even gotten it all. In the process, I've discovered (a) the system drive is showing signs of impending failure, and (b) the owner has been using the system's old crusty IE-6 instead of the up-to-date Firefox I've provided for him. So naturally, thinking I had a relatively stable system, I tried to hit the Windows Update site to install IE-8, in case further training doesn't stick. The update site told me it needed to update the installer, and I started that process. Soon after, wuauclt.exe started crashing, reporting addresses in module esent.dll. There's a Microsoft KB (910437) on a problem with that DLL, so I downloaded the hotfix and installed. The crashing did not stop. I attempted to install SP3 from the offline installer, but that didn't fix the issue either. The system is reporting a few hard drive / IDE controller errors, but they don't correlate to the crashes, so they aren't the direct cause. I've also attempted to rollback to the time between the infection removal and the first crashes, but that doesn't help. Question The hotfix I tried to install dealt with problem in transaction logs of the Extensible Storage Engine (ESE) database. I suspect this issue is similar, but that the database itself (whatever the ESE database is) is corrupted. Is there a way to clean or clear this database so that system operation returns to normal? Can someone enlighten me as to what the ESE database actually is, and where it resides? Can I just locate some files and delete them to bring this under control?

• Application (was Firefox) crash on first load on Ubuntu Linux on older Dell Laptop

  - by Ira Baxter

  I've had a Dell Latitude laptop since about 2000 without managing to destroy it. A month ago the Windows 2000 system on it did something stupid to its file system and Windows was completely lost. No point in reinstalling Windows 2000, so I installed an Ubuntu Linux on the laptop. Everything seems normal (installed, rebooted, I can log in, run GnuChess, poke about). ... but ... when I attempt to launch Firefox from the top bar menu icon, I get a bunch of disk activity, the whirling cursor icon goes round a bit and then (WAS: everything stops: icon, mouse. Literally nothing happens for 5 minutes. Ubuntu is dead, as far as I can tell. EDIT : on further investigation, spinning icon, mouse operated by touchpad freeze. There's apparantly a little disk activity occuring about every 5 seconds. I wait 5-10 minutes, behavior doesn't change) A reboot, and I can repeat this reliably. So on the face of it, everything works but Firefox. That seems really strange. The only odd thing about this system when Firefox is booting is that while it has an Ethernet port (that worked fine under Windows), it isn't actually plugged into an Ethernet. As this is the first Firefox boot since the Ubuntu install, maybe Firefox mishandles Internet access? Why would that crash Ubuntu? (I need to go try the obvious experiment of plugging it in). EDIT: I tried to run the Disk manager tool, not that I cared what it was, just a menu-available application. It started up like Firefox, I get a little tag in the lower left saying Disk P*** something had started, and then the same behavior as Firefox. At this point, I don't think its the Ethernet. Is it possible that the Ubuntu disk driver can't handle the disk controller in this older laptop? The install seemed to go fine.

• linux keeps disconnecting from wireless network

  - by Matteo Ceccarello

  I'm running Arch Linux on an Acer laptop and my wirless connection doesn't stay up. After a while it disconnects, and when I try to reconnect I get stuck with a "Waiting for authorization" message. I have to retry several times before getting the connection stay up for few minutes. This happens with both networkmanager and wicd. The strange thing is that the iMac that sits next to the laptop connects fine, and when I use my laptop within the university wireless network it works normally. How can I solve this problem? EDIT: I've tried to connect manually following the steps iwlist wlan0 scan wpa_supplicant -i wlan0 -c /etc/wpa_supplicant.conf dhcpcd wlan0 and it works, I can ping google. However, looking to wpa supplicant output I see that it keeps connecting and disconnecting. I'm using WPA2, and this seems to be a problem in authentication. EDIT 2: as pointed out in the answers I forgot to mention my hardware/software specifications: kernel: Linux 3.0-ARCH wireless card: # lspci | grep -i net 07:00.0 Network controller: Intel Corporation WiFi Link 5100 module used # lsmod | grep -i 80211 mac80211 216021 1 iwlagn I use a Netgear DGN1000 modem/router My dmseg output is shown here http://pastebin.com/8Tf7iage

• How to extend a Linux PV partition online after virtual disk growth

  - by Yves Martin

  VMware allows to extend the size of a virtual disk online - when the VM is running. The next expected steps for Linux system are: extend the partition: delete and create a larger one with fdisk extend the PV size with pvresize use free extents for lvresize operations and then resize2fs for file system But I am stuck on the first step: fdisk and sfdisk still display the old size for the disk. My disk is a SCSI virtual disk connected thanks to the virtual LSI Logic controller. How to refresh the virtual disk size and partition table information available in Linux kernel without reboot ? As far as I know all that steps are possible for a running Windows, without reboot and even without any user actions thanks to VMWare tools. On Linux, I expects to do all steps online too and I already know steps 2, 3 and 4 work online. But the first one - change partition size declared in the partition table (still) seems to require a reboot. Update: My system is a Debian Lenny with kernel 2.6.26 and the disk I have extended is the main disk with a large PV containing the "root" LV for "/".

• 10 GigE interfaces limits single connection throughput to 1 Gb on a ProCurve 4208vl

  - by wazoox

  The setup is as follow : 3 Linux servers with Intel CX4 10 GigE controllers and an X-Serve with a Myricom 10 GigE CX4 controller are connected to a ProCurve 4208vl switch, with a myriad of other machines connected through good ol' 1000 base-T. The interfaces are actually set up as 10 Gig, according to both the switch monitoring interface and the servers (ethtool, etc). However a single connection between two 10 GigE equipped machines through the switch is limited to exactly 1Gb. If I connect two of the 10 GigE machines directly with a CX4 cable, netperf reports the link bandwidth as 9000 Mb/s. NFS achieves about 550 MB/s transfers. But when I'm using the switch, the connection tops at 950 Mb/s through netperf and 110 MB/s with NFS. When I open several connections from 3 of the machines to the 4th, I get 350 MB/s of NFS transfer speed. So each individual 10 GigE ports actually can reach much more than 1 Gb, but individual connections are strictly limited to 1 Gb. Conclusion : the 10 GigE connection through the switch behaves exactly like a trunk of 10 1 Gb connections. That doesn't make any sense to me, unless HP planned these ports only for cascading switches or strictly for many-clients-to-single-server connection. Unfortunately this is NOT the envisioned setup, we need big throughput from machine to machine. Is this a not-so-known (or carefully hidden...) limitation of this type of switch? Should I suggest seppuku to the HP representative? Does anyone have any idea on how to enable a proper behaviour ? I upgraded for an hefty price from bonded 1Gb links to 10 GigE and see exactly ZERO gain! That's absolutely unacceptable.

• SSD/HDD not exceeding 120 MB/s

  - by skiwi

  SO here is the situation: First this was my old PC, it had a 2x 1TB RAID 0 and a Corsair Force 3 SSD in it. This were the old speeds, measured by HDTune Pro. 2x 1TB RAID 0: Corsair Force 3 SSD Then my dad got my PC and we had several issues, in the end turned out both RAID and SSD controller were malfunctioning causing BlueScreens on 100% load. Removed the RAID 0, but leaving the HDD's intact and bought an Samsung 840 EVO 120GB, though the Corsair SSD is still in the system, just not as sytem disk anymore. 1TB HDD (one of them): Corsair SSD: Samsung SSD: We did not assemble the PC ourselves, so answering some technical questions might be more difficult, though we will do our best. First thing we noticed is that the Samsung 840 EVO is no where reaching it's advertised speed, even an Samsung 840 250GB (non-EVO) is reaching 350 MB/s in my own PC. Then we noticed that both SSD's are capped at 120 MB/s exactly, not sure if this is being caused by HDTune Pro, but very unlikely. And even worse, the Corsair Forza 3 was running faster before the system got reassembled. Does anyone have any clue what is going on?

• smartctl short test doesn't seem to complete

  - by Cédric COPY

  I am working on project which involve automated HDD testing through smartctl. The station is working fine on most product, but I have two specific products that fail the smartctl test. Those two product are both WD product (WD2500BUDT series) Smartctl behaviour is quite strange, in fact the test is launched without any problem, i wait about 2min (test length), and when i check the smartctl, i have got no result at all. It's like I hadn't launched any test (no fail, no success in smartctl result). No error return on command, nothing in syslog, .. As i said before, the test is working for other product, thousands products worked well with this test. The main smartctl command used are : smarctl -t shortest /dev/sdX #Launch test smartctl -l selftest /dev/sdX #Look at test result I have tried to use: smartctl -s on /dev/sdX or smartctl -o on /dev/sdX But doesn't change anything. The system is using Debian 6.0, smartctl v5.40 (rev 3124) x86_64, HDD are plug through SATA to PCI controller. I have 4 HDD connected at a time. Well if anyone has some hints to give with this problem, because I have no idea how can i fix this. Thanks in advance. PS: Not sure if it was a serverfault topic, sorry if i was wrong!

• Dell Driver Support for Latitude E6320 Windows 7 Enterprise

  - by IamPolaris

  I recently did a reinstall of Windows 7 Enterprise on a Dell Latitude E6320, which is a 64 bit system. After the install process, and doing typical Windows Update stuff, I looked at my Device Manager and found that I had devices which were missing drivers. My missing drivers: After going to the Dell Support site and looking at the files, and doing some sleuthing I found the following support document: http://downloads.dell.com/utility/Latitude%20E-Family%20%20Mobile%20Precision%20Re-Image%20How-To%20Guide%20-%20A03%20Rev%203%200.pdf This document hints in appendix C that the Broadcom USH is the Control Point Security and the Unknown device is Micro freefall sensor. The network controller is my wireless, as I cannot connect wirelessly, and the final missing driver I am not sure. Attempting to install the control point security exe on the support page will not work. After downloading, I am given the message that I am attempting to install a 32 bit driver on a 64 bit machine EVEN THOUGH I selected the win7 64 bit option from the support page. Beyond that, some of the drivers (Which are confusing to read and hard to understand what they do) and the system utilities which are supposedly supposed to make this process simpler will either a) not run because they are 32 bit exe's or b) the support page cannot find the file attempted to download. Is there anything I can do to get (at the very least) my wireless running, but idealistically all of my drivers. A solution which assumes Dell is completely incompetent would be ideal. :P Some forums have said that I should download the chipset driver, others say to get the system utility file (DSS_UTIL_WIN_R282536.EXE). I have had no luck as of yet...

• Password Authentication Fails - NTLMv2

  - by JMeterX

  Environment: Windows 2000 sp4 EDIT: Domain Controller with no trust setup with the Win2008 Server Windows XP machines Windows 2008 Server Netapp NAS Problem: We have a shared folder that resides on a NAS using a Windows 2008 AD for the authentication with the proper permissions setup. When the Windows 2000 machine tries to open the share residing on the Win2008 machine, it is prompted for a username and password. Upon entering the credentials it continuously re-asks for credentials. Important Details: The Windows 2000 machine can ping both the XP machines and the Windows 2008 Server The Windows 2008 machine is mandated to only use NTLMv2 The Windows 2000 machine was originally set to NTLM but was recently switched to NTLMv2 if negotiated for the purpose of trying to connect to the share. As I am sure it will come up, we are using Windows 2000 because of contractual obligations Questions: Why is password Authentication failing in this case? After setting a GPO for the Win2000 machine for it to use NTLMv2, do we need to reboot the machine for the changes to take affect? We used SECEDIT to update the GPOs without rebooting. UPDATE We checked both of the 2008 Domain Controllers to find an error code. We received: Microsoft_Auth_Package_V1_0 0xc000006a Event ID: 4776 I know this to be an authentication error via THIS article "The value provided as the current password is not correct" We know this password to be correct, but since these two domains (Win2000 & Win2008) do not have a trust setup what authentication account needs to be used? One that resides on the Win2000 hosted domain?

• Server 2003 PDC DNS not working..Failover server is...

  - by Seth

  In the midst of trying to utilize proc power, i create a fault tolerant DNS server a while ago. Since, Ive been trying to add another controller for exchange. So I thought I would revert back to a single primary DNS for the meantime and now Im balancing on a thread. The server i thought I uninstalled DNS, is still acting as DNS. And now the PDC does not resolve. Can anybody walk me through, Im overwhelmed and cant think straight... Im afraid if anyone restarts their machine they wont have internet. Update Ok so from the beginning. I was configuring Exchange on a new server 2008. How it happened I dont know, but it started to not resolve DNS. (exclamation mark on NIC) even though everything was static. So ultimately I decided to remove the server from the problem, because I noticed DNS was in disarray if I used the DNS IP of the first server. This is when I tested with nslookup on each DNS server. I had uninstalled DNS from the second server, but nslookup was still resolving with that IPaddress, which has me all wound up cause I dont understand. So, since the first DNS server isn't resolving, Im assuming if the second one isnt configured right I'll loose internet. Im just confused and dont know where to start troubleshooting...

• Windows 8 Pro Homegroup Not Allowing Access to Shared Files

  - by Jack Herr

  I have two pc's and a laptop. With all three running Windows 7, homegroup worked perfectly, with all computers able to access the files on the others exactly as one would expect. I installed Windows 8 Pro, which I downloaded recently from the MSDN website, on the laptop. From the info on the MSDN website, I believe the version downloaded is the official release version, not a release candidate. The install preserved all settings, apps, and files. I cannot connect to the homegroup from the laptop. Well, not exactly. I joined the homegroup during the install, and later left and rejoined, that was advertised as being offered by one of the pc's (not sure why that one was picked and not the other or both). This homegroup appears in my "computer" folder in the file explorer, offering files from that pc. But it excludes documents (only the music, pix, videos, and playlists folders on the one computer appear). I can actually access those files from the laptop. But the Homegroup folder, which actually shows all the computers by account and computer name and includes documents from both computers, does not open those folders when clicked. The computers listed by name in the Network folder give me a login that doesn't work. It asks for a username and password, no combinations of which work. Further, the following error message appears before the login is even attempted: "The system cannot contact a domain controller to service the authentication request. Please try again later." The two windows 7 pc's continue to share all files, including documents, seemlessly. I can also get to the laptop shared files, which I shared during setup, from either pc. Any ideas?

• DNS request times out then succeeds on my local network. Why?

  - by Dan

  I have a W2K3 Server that is the Domain Controller and also the DNS server. I wanted to make another DNS zone on my network called "something.local" and then make 'A' records to point requests like 'admin.something.local' and 'www.something.local' to machines on my network. I keep getting DNS timeouts but then after 2 tries it succeeds. Why would this happen? How can I troubleshoot? From my desktop I run: nslookup admin.something.local and get: Server: server.domain.com.au.local Address: 192.168.0.10 DNS request timed out. timeout was 2 seconds. DNS request timed out. timeout was 2 seconds. Name: admin.something.local Address: 192.168.0.191 If I go back the other way: nslookup 192.168.0.191 I get: Server: server.domain.com.au.local Address: 192.168.0.10 Name: admin.something.local Address: 192.168.0.191 My DNS server address is 192.168.0.10. The new DNS zone is not hooked up to active directory. I do not have much experience with DNS. Yesterday it was working fine. I have tried doing an 'ipconfig /flushdns' on both my desktop and the DNS server

• Virus cleanup; Windows Automatic Updates service crashes in esent.dll

  - by quack quixote

  Background I'm doing system recovery on an old WinXP SP1 system brought to me on suspicion of virus infection. After taking preliminary backups, I used MalwareBytes to detect and clean the infection. I might've even gotten it all. In the process, I've discovered (a) the system drive is showing signs of impending failure, and (b) the owner has been using the system's old crusty IE-6 instead of the up-to-date Firefox I've provided for him. So naturally, thinking I had a relatively stable system, I tried to hit the Windows Update site to install IE-8, in case further training doesn't stick. The update site told me it needed to update the installer, and I started that process. Soon after, wuauclt.exe started crashing, reporting addresses in module esent.dll. There's a Microsoft KB (910437) on a problem with that DLL, so I downloaded the hotfix and installed. The crashing did not stop. I attempted to install SP3 from the offline installer, but that didn't fix the issue either. The system is reporting a few hard drive / IDE controller errors, but they don't correlate to the crashes, so they aren't the direct cause. I've also attempted to rollback to the time between the infection removal and the first crashes, but that doesn't help. Question The hotfix I tried to install dealt with problem in transaction logs of the Extensible Storage Engine (ESE) database. I suspect this issue is similar, but that the database itself (whatever the ESE database is) is corrupted. Is there a way to clean or clear this database so that system operation returns to normal? Can someone enlighten me as to what the ESE database actually is, and where it resides? Can I just locate some files and delete them to bring this under control?

• Allowing non-admin users to unstick the print spooler

  - by Reafidy

  I currently have an issue where the print que is getting stuck on a central print server (windows server 2008). Using the "Clear all documents" function does not clear it and gets stuck too. I need non-admin users to be able to clear the print cue from there work stations. I have tried using the following winforms program which I created and allows a user to stop the print spooler, delete printer files in the "C:\Windows\System32\spool\PRINTERS folder" and then start the print spooler but this functionality requires the program to be runs as an administrator, how can I allow my normal users to execute this program without giving them admin privileges? Or is there another way I can allow normal user to clear the print que on the server? Imports System.ServiceProcess Public Class Form1 Private Sub Button1_Click(sender As System.Object, e As System.EventArgs) Handles Button1.Click ClearJammedPrinter() End Sub Public Sub ClearJammedPrinter() Dim tspTimeOut As TimeSpan = New TimeSpan(0, 0, 5) Dim controllerStatus As ServiceControllerStatus = ServiceController1.Status Try If ServiceController1.Status <> ServiceProcess.ServiceControllerStatus.Stopped Then ServiceController1.Stop() End If Try ServiceController1.WaitForStatus(ServiceProcess.ServiceControllerStatus.Stopped, tspTimeOut) Catch Throw New Exception("The controller could not be stopped") End Try Dim strSpoolerFolder As String = "C:\Windows\System32\spool\PRINTERS" Dim s As String For Each s In System.IO.Directory.GetFiles(strSpoolerFolder) System.IO.File.Delete(s) Next s Catch ex As Exception MsgBox(ex.Message) Finally Try Select Case controllerStatus Case ServiceControllerStatus.Running If ServiceController1.Status <> ServiceControllerStatus.Running Then ServiceController1.Start() Case ServiceControllerStatus.Stopped If ServiceController1.Status <> ServiceControllerStatus.Stopped Then ServiceController1.Stop() End Select ServiceController1.WaitForStatus(controllerStatus, tspTimeOut) Catch MsgBox(String.Format("{0}{1}", "The print spooler service could not be returned to its original setting and is currently: ", ServiceController1.Status)) End Try End Try End Sub End Class
