• Can a Windows Domain play along with a Hosted Exchange service?

  - by benzado

  I'm setting up a computer network for a small (10-20 people) company. They are currently using a Hosted Exchange service they are totally happy with. Other than that, they are starting from scratch (office doesn't even have furniture yet). They will need some kind of file sharing server set up in their office. If I set up a machine as a file server and nothing more, users will have three passwords to deal with: local machine, file server, and email. If I set up a Domain Controller, identities for local machine and file server will be the same. But what about the Hosted Exchange server? Must the users have a separate email password, or is it possible to combine the two? (I realize it might depend on the specific hosting provider, but is it possible?) If not, it seems like I have these options: Deal with it: users have a separate email password. Host Exchange on the local server: more than they want to manage in-house? Purchase a hosted VPS, make it part of the domain, and host Exchange there. (Or can/should a VPS be a domain controller?) I realize I have a lot of questions in there. The main one: is there any reason to use a Hosted Exchange service if I'm setting up other Windows services?

• IP tables blocking access to most hosts but some accesses being logged

  - by epo

  What am I getting wrong? A while back I locked down my web hosting service while hardening it or at least trying to. Apache listens on port 80 only and I set up iptables using the following: IPS="list of IPs" iptables --new-chain webtest # Accept all established connections iptables -A INPUT --protocol tcp --dport 80 --jump webtest iptables -A INPUT --match state --state ESTABLISHED,RELATED --jump ACCEPT iptables -A webtest --match state --state ESTABLISHED,RELATED --jump ACCEPT for ip in $IPS; do iptables -A webtest --match state --state NEW --source $ip --jump ACCEPT done iptables -A webtest --jump DROP However looking at my apache logs I notice various log entries in access_log, e.g. 221.192.199.35 - - [16/May/2010:13:04:31 +0100] "GET http://www.wantsfly.com/prx2.php?hash=926DE27C156B40E55E4CFC8F005053E2D81E6D688AF0 HTTP/1.0" 404 206 "-" "Mozilla/ 4.0 (compatible; MSIE 6.0; Windows NT 5.0)" 201.228.144.124 - - [16/May/2010:11:54:16 +0100] "GET /w00tw00t.at.ISC.SANS.DFind:) HTTP/1.1" 400 226 "-" "-" 207.46.195.224 - - [16/May/2010:04:06:48 +0100] "GET /robots.txt HTTP/1.1" 200 311 "-" "msnbot/2.0b (+http://search.msn.com/msnbot.htm)" How are these slipping through? I don't mind the indexing bots (though I am a little surprised to see them get through). I suppose they must be getting through using the ESTABLISHED,RELATED rules. And no, I can't for the life of me remember why the first match state rule is there So 2 questions: is there a better way to set up iptables to restrict access to specified hosts? How exactly are these 3 examples slipping through?

• How to diagnose storage system scaling problems?

  - by Unknown

  We are currently testing the maximum sequential read throughput of a storage system (48 disks total behind two HP P2000 arrays) connected to HP DL580 G7 running RHEL 5 with 128 GB of memory. Initial testing has been mainly done by running DD-commands like this: dd if=/dev/mapper/mpath1 of=/dev/null bs=1M count=3000 In parallel for each disk. However, we have been unable to scale the results from one array (maximum throughput of 1.3 GB/s) to two (almost the same throughput). Each array is connected to a dedicated host bust adapter, so they should not be the bottleneck. The disks are currently in JBOD configuration, so each disk can be addressed directly. I have two questions: Is running multiple DD commands in parallel really a good way to test maximum read throughput? We have noticed very high SWAPIN-% numbers in iotop, which I find hard to explain because the target is /dev/null How shoud we proceed in trying to find the reason for the scaling problem? Do you thing the server itself is the bottleneck here, or could there be some linux parameters that we have overlooked?

• vSphere - datastore falling off a host

  - by Chadddada

  Recently we have been running the vCheck powershell script daily in order to help in monitoring our vSphere ESX 4.0 environment. One of the oddities that we have been seeing is that some of the datastores on the SAN don't always show up on every host. Our hosts are connected redundantly, via FC, to some brocade FC switches, which then connect via fiber to our EMC Ax4 SAN. While all the datastores are presented to each host we have, and they see them initially, they sometimes seem to fall off and are no longer visible. It easy enough to rescan for datastores and add them back to the hosts the hosts but this seems to be an error. Has anyone else seen this or know why it may be happening? Responses to questions: 1. Is it always the same ESX servers that lose their connection? – Scott Warren No this happens randomly on random hosts. If a VM is running on a particular host, of which the VM's disks are on a SAN datastore, then that datastore won't disappear. It seems to happen if a host doesn't touch a datastore for a bit and it just forgets about it.

• Custom Domain for Google App Engine and Google Apps

  - by Kevin

  I have set up and configured Google App Engine and Google Apps to use my custom domain with a cname 'www'. I have configured my DNS (via fasthosts.co.uk) with the cname and pointed it to ghs.google.com. I can access the website using the google app engine domain at capel-y-crwys.appspot.com but I can't access it via my custom domain www.capelycrwys.org.uk. I have allowed several days for propagation of the DNS etc. The really strange this is I can access the app via my custom domain when I use the web browser on my Android mobile phone. I can't access the app via my custom domain from my home internet connection, my work internet connection or a friends internet connection. I tried a few online web proxies and I can access the app via the custom domain. I posted this question on the google forums code.google.com/appengine/forum/?place=topic%2Fgoogle-appengine%2FfUP-G_0FKE4%2Fdiscussion and a commentor has said he could access the app via the custom domain. So why can't I access it direct via my home internet connection etc? I've tried loads of google searching and even found a similar sounding post here on serverfault serverfault.com/questions/208461/custom-domain-name-server-not-found-google-app-engine-and-google-apps but it doesn't have an answer that helps me.

• Sun Power Button Won't Shut Down System

  - by user36680

  Background: We are running NIS and have NFS mounts from a Solaris 10 workstation to a Solaris 8 server. If the workstation loses its network connection for some reason, when I look at the workstation's console I see repeated messages of the form: <date> <time> <hostname> ypbind[<pid>]: NIS server not responding for domain "<domain>"; still trying. If I try to login at the console as a user, it won't work because it can't authenticate my account through NIS. Also, it won't return to a login prompt again, so I can't log in as root. If I press the power button (don't hold it in) on the workstation, I see: <date> <time> <hostname> power: WARNING: Power off requested from power button or SC, powering down the system! Shutdown started. <date> <time> Changing to init state 5 - please wait. <date> <time+2 minutes> <hostname> power: WARNING: Failed to shut down the system! And continue to see messages of the form: <date> <time> <hostname> ypbind[<pid>]: NIS server not responding for domain "<domain>"; still trying. So, the questions are How do I make NIS stop trying (because I know it will fail)? Why won't it shut down?

• Things to check for an internet-facing email server.

  - by Shtééf

  I'm faced with the task of setting up a public-internet-facing email server, that will be relaying mail for all of our other servers in the network. While the software in itself is set up in few keystrokes, what little experience I have with managing an email server has thought me that there are tons of awkward filtering techniques employed by other email systems. Systems that my own server will inevitably interact with a some point. Hence, my questions: What things should be kept in mind and double checked when setting up an email server? What resources are available for checking if my email server is set-up correctly? I'm specifically NOT looking for instructions for any given mail server, such as Exchange or Postfix. But it's okay to say: “you should have X and Y in your set-up, because when talking to server software Z, it typically tries to weed out open relays by checking for these.” Some things I've discovered myself: Make sure forward and reverse DNS are set up. Mail servers tend to do a reverse lookup for the peer IP-address when receiving. Matching a reverse look up with a follow-up forward lookup is probably employed to weed out open relays run through malware on home networks. Make sure the user in the From-address exists. The From-address is easily spoofed. A receiving mail server may try to contact the mail server in the From-domain, and see if the From-user actually exists.

• Ubuntu 12.10, Unity, AMD 12.11 beta drivers, AMD APP SDK 2.7 and OpenCL detection of multiple gpus

  - by junkie

  I'm using Ubuntu 12.10, AMD 12.11 beta drivers, AMD APP SDK 2.7 and OpenCL. I have three amd radeon 7990s plugged in each of which are a dual 7970 so I have six gpus altogether. I plan to go up to eight in a few days. Windows couldn't use even 4 but linux works fine with 6 so far. The strange thing is that the six gpus are only detected by OpenCL in unity (the ubuntu default window manager). If I switch to e17, blackbox or fluxbox or anything else for that matter OpenCL only detects one. I'm using a simple OpenCL program to list all devices to check. I've also checked the output of aticonfig --list-adapters, fglxinfo and clinfo. The first two always show six in all window managers wheras clinfo shows 6 in unity but 1 gpu in all other WMs. I'm also using an X config generated by aticonfig --initial -f --adapter=all. I'm also only using one monitor. I've also checked using lsmod that the fglrx module is loaded in all WMs. So I have two questions. Why does OpenCL see six gpus only in unity? How can I enable six gpus on other lightweight WMs? Basically I'm getting at what determines how many gpus the OpenCL runtime sees? Thanks.

• How to handle files that don't need version control in mercurial

  - by richardh

  I am new to mercurial, and for the most part do LaTeX reports and statistical calculations in R using .csv and/or .sqlite files. Re LaTeX, all I really care is the .tex file. Re R, I don't need version control on the .csv or .sqlite files because they are static. When I do 'hg add' for a repo with a .csv and/or .sqlite file, I get a warning like: rev2.sqlite: up to 3070 MB of RAM may be required to manage this file (use 'hg revert rev2.sqlite' to cancel pending addition) So I revert and subsequently use adds like hg add -X *.sqlite. I guess I really have two questions: (1) Should I ignore these warnings? Because these large files are static, can I just add to the repo knowing that the diff files will always be empty and not worry about wasted resources? (2) If I should keep excluding these files from the repo, is there away that I can fix this option? I.E., add to my .hgrc file something that always appends an option like -I *.tex -I *.R to my 'hg add' commands? Thanks!

• External HDD incorrectly detected as internal - how change to enable hot swap/eject?

  - by Sam

  Hi All, I have win 7 x64 Home Prem. The HDD is a seagate barracuda, 7200.7 ST3120827AS. 3.5", Serial: 3ms006n6, Firmware: 3.42 (no further updates) NexStar CX External case (drivers installed). I have three drives: WD320 with OS installed WD750 data storage (internal) seagate 120 (external) - connected via esata board connected to sata on motherboard (MSI p43 neo) Tried uninstalling HDD in device manager to no effect. Also the internal WD750 is detected as an external drive and win taskbar icon allows for it to be ejected (unlike the seagate). All drives are configured - Online, Simple, Basic, NTFS, Active, Primary Partition (except c drive). The seagate was previously used as a primary disk with XP operating system so I deleted the volume and created/reformatted (not quick). HDD is no longer "Active". But did not fix problem. Background Originally, I installed win 7 with the bios set to IDE and forgot to install the chipset drivers. Then I changed win 7 to install the AHCI drivers, changed the bios to AHCI and rebooted. Win 7 loaded drivers but WD HDD gave problems/crashed. I installed chipset drivers and latest intell storage matrix software thingie (in safe mode). Everything worked fine after that except for the problem of not corrrectly detecting the external drive] I have noticed that under the driver properties (and similarly in the registry) the two drives are configured differently (e.g. in driver details property capabilities for the WD the value is set to 0000006, CM_DEVCAP_REMOVABLE & EJECTSUPPORTED - whereas the seagate shows 0000080 & CM_DEVCAP_SURPRISEREMOVALOK). Any easy way to configure things? I tried physically swapping the sata connections on the mainboard without success So far I have found that a solution to my problem might be to perform some reg changes: http://superuser.com/questions/12955/how-do-i-remove-the-option-to-eject-sata-drives-from-the-windows-7-tray-icon

• Removing Paths/ Landing Pages From SharePoint Search Results

  - by j.strugnell

  Hi there, We've been asked by a client to remove a number of pages from being shown up in their public website search results page. I've been into the SSP and created Crawl Rules to remove these pages. All seemed to have worked ok but we have an issue in that landing pages are still showing up in their "www.domain.com/sitearea/" form but not in their "www.domain.com/sitearea/pages/default.aspx". For each of this type of page we have created one rule to "Exclude" the "aspx" path and another rule to include the "/" path but to "Follow links on the URL without crawling the URL itself". We tried adding rules to exclude the "/" format but that only resulted in all results underneath that being excluded. Does anybody know how to remove the "area/pages/default.aspx" and the "area/" pats from Search Results? I'm not sure if it's the "done thing" to ask 2 questions in one but this is in a similar vein so it should be ok. I was wondering if anyone knew of a tool (or if it is possible) to allow site admins to exclude pages from search results (not via SSP/Crawl Rules). I know they can do it at the site level but I was wondering if anything out there enabled this to be done at the page level through either Page or Site Settings?

• NAT and P2P router crash

  - by returnFromException

  So..i had this argument with my networks teacher. He said that some people complains about router crashes due to many entrys on NAT tables on a router. I didnt understand and i asked: "If the application uses the same port, why does the router crash?. It should have only one entry (pc-ip,pcport;public-ip,public-port)". And he said: "it doesnt matter its using the same port". I got the idea that NAT creates an entry for every packet that passes trought it. Iam assuming NAT with overloading as you might have guessed. So the questions are: 1-How does nat entrys are created? On a packet basis or connection basis? I mean: suppose i send a udp packet..does the router create an entry? 2-When i start a TCP connection, does the router create a persistant nat entry until the connection closes? 3-Was my teacher right? The NAT table can overload assuming an aplication on the same port sending packets? Thanks in advance.

• Windows 7 access denied to executables.. by what?

  - by stijn

  Ever since I started using Windows 7 this problem has been bothering me. From time to time I see similar questions popping up on misc forums, but never did I see an answer. Here are two scenarios that nearly always reproduce it: the explorer way with explorer, navigate to a directory containing at least one exe file go one directory up immediately delete the directory just navigated to yields Folder Acces Denied dialog stating You need permission to perform this action You require permission from Administrators to make changes to this folder, with the buttons try Again and Cancel hitting Try Again never works immediately. Waiting a minute or so and then clickig it again does work note: if in step 2 and waiting a minute or more before going up one directory, the problem does not occur and the folder can be deleted the visual studio way build a project producing an exe file run the executable then close it immediately build the project again (by changing a single character in a source file for example) yields fatal error LNK1168: cannot open /path/to/the.exe for writing note: if in step 2 and waiting a minute or more before building again, the problem does not occur some specs happens both on Windows 7 32 and 64 bit, with VS2008/2010/2011 happens on 3 different machines I do not have a virusscanner of any kind I do have a bunch of services disabled, but nothing that prevents Windows from running normally, UAC is disabled as well happens on any type of disc I always use a user account that is in the Administrators group Obviously both scenarios are very similar and extremely reproducable. So I figured some process must have the file open for some reason, and release it again later. However, using systinternal's handle -a the exe file in question never shows up. (that is the correct way to use handle, right?) So while explorer/VS are reporting they cannot access the file, handle.exe says it's not in use anywhere. This leaves me rather clueless, so I'm wondering if someone can come up with a solution: why does this happen, and how to solve it?

• Connections to SSH and Samba suffer from heavy delay

  - by Till Helge Helwig

  There are a lot of questions about SSH connections being delayed, which usually can be fixed by disabling the DNS lookups. Unfortunately this doesn't seem to be my problem. Our development server is accessed via SSH and Samba. When opening a connection to the server (either SSH or Samba) it takes a very long time. Accessing a Samba share via Windows is basically impossible because there is a timeout. Using smbclient works, but takes ages. When opening a SSH connection I get immediately prompted for the password and after hitting Enter the terminal instantly shows the MOTD. Afterwards it takes about a minute for the prompt to appear. I watched the load of the server while connecting via SSH and Samba and could not find anything out of order. There is nothing out of the ordinary running and hogging up memory and CPU or something. I have no clue where this delay might come from. I already tried UseDNS no in sshd_config and proxy_dns = no in smb.conf, but to no avail. Any idea about what might cause this would be greatly appreciated!

• Windows 8 using as a webserver

  - by Jason

  I have a few hobby websites that I currently host on CentOS 6. Apache, mail serving, PHP, MySQL nothing special. In the past I used Windows XP to do this same task, for years, and I was OK. I switched to Linux and for the last few years it has been such a pain. updates break, certain apps only support certain distros without compiling from source. It prevents me from working on my hobby sites more because I am always fixing something. With Windows I locked it down, I run a hardware firewall and packet analyser, kept up on updates and A/V and never had a problem. I dont allow RDC from outside the local LAN, no FTP open, run OpenSSH on an obscure port.. I am considering switching to Windows 8 (since it is a cheaper license now that Windows 7) and running apache, HMailServer, PHP, MySQL, just like my CentOS install. My questions: I am not familiar with Windows 8, can the above be done like XP? No new security restrictions or the OS preventing this from happening? The machine is a Athlon 64-bit X2 with 32GB of RAM. Will Windows 8 see all of the RAM? Technically the machine came with Windows 7, and there is a serial number on it but I am sure I wiped away the Windows 7 recovery partition when I switched to Linux....

• Corrupted NTFS Drive showing multiple unallocated partitions

  - by volting

  My external hdd with a single NTFS partition was accidentaly plugged out (kids!)... and is now corrupted. Iv tried running ntfsfix - with no luck - output below.. When I look at the disk under disk management in Windows 7 it shows up as having 5 partitions 2 of which are unallocated - none have drive letters and it is not possible to set any (that option and most others are greyed out) - so I can't run chkdsk /f Iv tried using Minitool partition wizard which was mentioned as a solution to another similar question here. It showed the whole drive as one partition, but as unallocated, and the option -- "Check File System" was greyout. Is there anything else I could try ?

• How to transform a csv to combine matching rows?

  - by Christian Wolf

  I have a CSV file with some transaction data. Let's say date, volume, price and direction (sell/buy). Additionally there is a ID for each transaction and on each closing transaction (the newer one) there is a reference to the corresponding transaction. Classical database referencing. Now I want to do some statistics and draw some plots. This could be done via Octave, LaTeX/TikZ, Gnuplot or whatever. To do this I need both buy and sell price in one row. My thought was to preprocess the CSV to get another CSV containing the needed information and then to do the statistics. In the end I'd like to have a solution based on scripts and not on a spreadsheet as data might change often (exported from online DB). My actual solution (see http://paste.ubuntu.com/6262822/ ) is a bash script that parses the CSV line by line and checks if there exists a corresponding transaction. If found, a new row is written to the destination CSV. If not a warning is printed. The bad news: For each row in the source file I have to read the whole file a few times. This causes long running times of 10sec for 300 lines. As the line number might rise soon (10k lines), this is not perfect. I am aware, that there are many shells to be opened in the script which might cause the performance problems. Now my questions: Is bash/awk/sed/.... a good way to do things? Should I first import all data into a "real" local database to use SQL? Is there an easy way to achieve the desired results?

• Distributed storage and computing

  - by Tim van Elteren

  Dear Serverfault community, After researching a number of distributed file systems for deployment in a production environment with the main purpose of performing both batch and real-time distributed computing I've identified the following list as potential candidates, mainly on maturity, license and support: Ceph Lustre GlusterFS HDFS FhGFS MooseFS XtreemFS The key properties that our system should exhibit: an open source, liberally licensed, yet production ready, e.g. a mature, reliable, community and commercially supported solution; ability to run on commodity hardware, preferably be designed for it; provide high availability of the data with the most focus on reads; high scalability, so operation over multiple data centres, possibly on a global scale; removal of single points of failure with the use of replication and distribution of (meta-)data, e.g. provide fault-tolerance. The sensitivity points that were identified, and resulted in the following questions, are: transparency to the processing layer / application with respect to data locality, e.g. know where data is physically located on a server level, mainly for resource allocation and fast processing, high performance, how can this be accomplished? Do you from experience know what solutions provide this transparency and to what extent? posix compliance, or conformance, is mentioned on the wiki pages of most of the above listed solutions. The question here mainly is, how relevant is support for the posix standard? Hadoop for example isn't posix compliant by design, what are the pro's and con's? what about the difference between synchronous and asynchronous opeartion of a distributed file system. Though a synchronous distributed file system has the preference because of reliability it also imposes certain limitations with respect to scalability. What would be, from your expertise, the way to go on this? I'm looking forward to your replies. Thanks in advance! :) With kind regards, Tim van Elteren

• Which revision control system for single user

  - by G. Bach

  I'm looking to set up a revision control system with me as a single user. I'd like to have access (read and write) protected using SSL, little overhead, and preferrably a simple setup. I'm looking to do this on my own server, so I don't want to use the option of registering with some professional provider of such a service (I like having direct control over my data; also, I'd like to know how to set up something like that). As far as I'm aware, what kind of project I want to subject to revision control doesn't really matter, but just for completeness' sake, I'm planning on using this for Java project, some html/css/php stuff, and in the future possibly as a synchronizing tool for small data bases (ignore that later one if it doesn't fit in with the paradigm of revision control). My questions primarily arise from the fact that I only ever used Subversion from Eclipse, so I don't have thorough knowledge of what's out there, what fits better for which needs, etc. So far I've heard of Subversion, Git, Mercurial, but I'm open to any system that's widely used and well supported. My server is running Ubuntu 11.10. Which system should I choose, what are the advantages of the respective systems, and if you know of any particularly useful ones, are there tutorials regarding the setup of the system I should choose that you could recommend?

• Why is my hg workbench & Adobe Reader toolbar icon a blank white page?

  - by Zasurus

  On my work's PC (windows 7 32bit) all Adobe Reader and hg Workbench icons on the toolbar (and general shortcuts for hg workbench) are just white pages (with the top left corner folded over). If you right click on the toolbar icon then right click on "TortoiseHg Workbench"(for hg workbench) then "Properties" then the "Change Icon..." button is greyed out (same for "Adobe Reader X"). Also the "Target:" is "TortoiseHg 2.4.0 (x86)" and is greyed out also the "Open File Location" is greyed out. This is the same for both Hg Workbench and Adobe Reader and seems to be the only thing that connects them. I have tried reinstalling to no avail. I also have local admin rights on the PC. I finally I have tried the following following questions without any luck (they aren't quite relevant to my issue but close): Adobe Reader program icon and pdf icons don't appear in Windows 7 Adobe PDF icon disappeared? Encase my description isn't enough to understand the issue here is a screenshot. As you can see the Hg Workbench icon (far left) and a pdf open in Adobe Reader X (second icon to from the left) are both blank and the shortcut is mainly greyed out.

• Create a PDF that defaults to flip on short edge when printed double-sided

  - by user568458

  We're creating a 2-page PDF brochure with a target audience who will print it on their regular office or home printers. If it is printed on a double-sided printer (common in offices), it'll come out correctly if set manually by the user to "Flip on short edge", but will come out with the second page upside down if default settings are used (flip on long edge). Our target audience aren't very tech-literate, and we've found that even within our own office network there is variation in the location of the 'Flip on short edge' setting - so it isn't realistic to give everyone who downloads the PDF instructions on how to change this setting or to expect everyone to find out how to change the setting off their own backs. So, when creating a PDF (ideally using Adobe InDesign or Acrobat, but if other software or hacking is needed that's fine...), is there a way to configure the PDF file itself so that when printed double-sided with default settings, it flips on the short edge? If possible, it'll be useful supplementary info to know how reliable any such methods are across different PDF readers (e.g. Adobe Reader, Acrobat, Mac Preview, inbuilt browser readers (e.g. chrome), FoxIt, etc). If questions about content creation like this aren't a great fit here, feel free to migrate it to the graphic design stackexchange site - this question seems to fall half way between the two sites

• Give Access to a Subdirectory Without Giving Access to Parent Directories

  - by allquixotic

  I have a scenario involving a Windows file server where the "owner" wants to dole out permissions to a group of users of the following sort: \\server\dir1\dir2\dir3: Read & Execute and Write \\server\dir1\dir2: No permissions. \\server\dir1: No permissions. \\server: Read & Execute To my understanding, it is not possible to do this because Read & Execute permission must be granted to all the parent directories in a directory chain in order for the operating system to be able to "see" the child directories and get to them. Without this permission, you can't even obtain the security context token when trying to access the nested directory, even if you have full access to the subdirectory. We are looking for ways to get around this, without moving the data from \\server\dir1\dir2\dir3 to \\server\dir4. One workaround I thought of, but which I am not sure if it will work, is creating some sort of link or junction \\server\dir4 which is a reference to \\server\dir1\dir2\dir3. I am not sure which of the available options (if any) would work for this purpose if the user does not have Read & Execute permission on \\server\dir1\dir2 or \\server\dir1, but as far as I know, the options are these: NTFS Symbolic Link, Junction, Hard Link. So the questions: Are any of these methods suitable to accomplish my goal? Are there any other methods of linking or indirectly referencing a directory, which I haven't listed above, which might be suitable? Are there any direct solutions that don't involve granting Read & Execute to \\server\dir1 or \\server\dir2 but still allowing access to \\server\dir1\dir2\dir3?

• which vista services can be disabled with impunity?

  - by GwenKillerby

  I use Vista on a HP pavilion DV2 laptop. When I look through all the services my laptop starts, it really seems there's way too much of it. I multi boot with XP and 7. Both startup in 40 seconds. Vista takes four minutes. Is there some software that can determine which services I don't need? On 7, there's no propietary HP stuff at all, yet it seems to run fine. Because all these service, there's a LOT of them and some just sit there doing nothing, monitoring for updates I don't really need or want or need to know about the second they're available. my laptop is the only computer i use at home, there's no home network, aside from the modem-router, which is cabled, not wifi. Take for instance Parental controls, and stuff for people with bad eyesight, Tablet PC. I really never use any of that stuff. Hope this question is specific enough. I've looked at the other questions but they didn't answer me. thanks, Gwen.

• Developing high-performance and scalable zend framework website [on hold]

  - by Daniel

  We are going to develop an ads website like http://www.gumtree.com/ (it will not be like this one but just to give you an ideea) and we are having some issues regarding performance and scalability. We are planning on using Zend Framework for this project but this is all that I'm sure off at this point. I don't think a classic approch like Zend Framework (PHP) + MySQL + Memcache + jQuery (and I would throw Doctrine 2 in there to) will fix result in a high-performance application. I was thinking on making this a RESTful application (with Zend Framework) + NGINX (or maybe MongoDB) + Memcache (or eAccelerator -- I understand this will create problems with scalability on multiple servers) + jQuery or maybe throw Backbone.js in there, a CDN for static content, a server for images and a scalable server for the requests and the rest. My questions are: - What do you think about my approch? - What solutions would you recommand for developing an high performance, scalable application expected to have a lot of traffic using PHP(Zend Framework 2)...I would be interested in your approch. I should note that I'm a Zend developer, I'm working with Zend for over 3 years, this is why I'm choosing it.

• Windows Server Connected to Domain Without Being Domain Controller

  - by saluce

  Can a Windows Server be connected to an Active Directory domain without being a domain controller? Here's the scenario: I want to use Windows Server 2012 to run several virtual machines for testing our web application in a variety of environments. We have a corporate domain, and I'd like to use the corporate login (or at least a common login) on each of the virtual machines without necessarily having to get IT to set up each virtual machine on the corporate domain. Also, I need the server itself to be able to authenticate domain logins (the app uses domain login information for users to login). However, I absolutely do NOT want it to be a DC on the corporate network. Thus, my questions: Can a Windows Server be connected to an Active Directory domain without being a DC? Can a Windows Server authenticate users on another domain without being a part of that domain? Can a Windows Server be a domain controller in a small network (comprised of just the server and itself) and use the corporate domain's Active Directory for authenticating user logins to the server, the web app, and the virtual machines?
