• How to setup certificate authentication for MS SQL server 2008 R2 ?

  - by Stephane

  Hello, I have to connect an (ADO) application running on a standalone Windows 2003 R2 server to a SQL 2008 R2 database that is a member of the domain. I have setup an SQL authentication account for this and hard-coded the password into the connection string but I wonder if it wouldn't be possible to use certificate-based authentication for this instead. I haven't been able to find any documentation regarding this apparently new functionality of SQL 2008 R2 anywhere. Could someone kindly point me at some good documentation ? Or at least a description of the functionality and whether it could be used in my case or not ? Thank you in advance

• Reset user passwd when you don't know it

  - by warren

  I have a small problem. I have shared keys setup on my domain, so I never type my password to login anymore. I've forgotten my password now. This is a problem because only my user can sudo. Password authentication for root has been disabled, so without my password, I cannot do maintenance on my web server. Is there a way to reset my password as my [now only] key-authenticated user? Specifically, can this be done on CentOS 4?

• CPU load, USB connection vs. NIC

  - by T.J. Crowder

  In general, and understanding the answer may vary by manufacturer and model (and driver, and...), in consumer-grade workstations with integrated NICs, does the NIC rely on the CPU for a lot of help (as is typically the case with a USB controller, for instance), or is it fairly intelligent and capable on its own (like, say, the typical Firewire controller)? Or is the question too general to answer? (If it matters, you can assume Linux.) Background: I'm looking at connecting a device (digital television capture) that will be delivering ~20-50 Mbit/sec of data to a somewhat under-powered workstation. I can get a USB 2 High-speed device, or a network-attached device, and am interested in avoiding impacting the CPU where possible. Obviously, if it's a 100Mbit NIC, that's roughly half its theoretical inbound bandwidth, whereas it's only roughly a tenth of the 480 Mbit/second the USB 2 "High Speed" interface. But if the latter requires a lot of CPU support and the former doesn't...

• Can I grant permissions on files in windows 7 using a security identifier from another machine

  - by Thomas

  I have an external hard drive, and I wish to grant permissions on some files to users from 2 different computers without having to hook it up to the 2 different computers. I know the SID of the user on the other computer, I'd like to know if and how I can grant permissions to files using the SID. I'm running Windows 7 Professional 64 bits, and "The Other" computer Win 7 Home Premium 64 bits, they are not in a domain, but separate computers on a home network (not even same homegroup). Note: Duplicated question with: Is there a way to give NTFS file permissions to users from other Windows installations?

• redirect all youtube video requests to a specific one

  - by iTayb

  I'm on an IT team in my company and I would like to block youtube to users. I don't want to just deny access to the whole youtube domain, but only to replace the .flv/.mp4 request with the one that I want. That way, if someone tries to watch youtube videos on the network, He'll get a video of why using our expensive bandwidth for pleasure is a no-no. I thought about using a packet manipulation program and just replace the video ID with something that I want, but I didn't manage to do it right.

• Windows/Samba connection error

  - by Gomibushi

  I have a Linux fileserver serving up /home for linux and windows users. I was able to connect from my windows client, but not from a DC. Then suddenly I could connect from the DC too. The linux servers run Centrify clients, and as such are part of the domain. All on same subnet. This is what the the log.smbd says, repeatedly: [2010/02/11 11:25:57, 0] lib/util_sock.c:read_data(534) read_data: read failure for 4 bytes to client 192.168.200.3. Error = Connection reset by peer On Windows it appeared as an "unknown error". EDIT: the error code is "0x80004005". We are developing a system depended on the samba share, and are worried this will appear again. It would be nice to pin point the root of this. Any ideas what this might be? Places to look?

• Use dns suffixes only on certain wireless networks?

  - by eidylon

  Hello all, quick question. I'm a software guy and networking is all black magic to me! I have a laptop which I use at home and at the office. In order to be able to more easily reference our servers at work, I have our domain name in the DNS suffixes on my TCP/IP settings on my wireless connection. This all works beautifully and I can reference our servers simply by name only. Now the problem... When I go home, it still has those suffixes in there, and I cannot access other servers because it appends the DNS suffixes to the server names. Is there a way I can set up DNS suffixes so that they are only applied when connected to a certain wireless network (I'm thinking by SSID).

• vhost.conf with plesk makes infinite loop

  - by user134598

  So I'm trying to make rewrite rules for my just migrated site and now we're using PLESK (unfortunately in my opinion). So, in order to make those rewrites I'm using the vhost.conf file in mydomain/conf folderm and I execute: /usr/local/psa/admin/sbin/websrvmng -u --vhost-name=mydomain.org so that includes my file into the httpd configuration. However, no matter what I write in my vhost.conf file, it will make my site go in an infinite loop whenever I try to load an URL that's not just the domain. Example: mydomain.org Works just fine. mydomain.org/event/nameofevent Will try endlessly to load and eventually my browser will detect that infinite loop. I though I was writing something incorrectly in my vhost.conf file but I even tried it with the file empty (not a single line). It will still try to load endlessly. Anybody can hint me if I'm skipping a step before (like any activation that should be done beorehand or something). Thanks in advance.

  Im running nginx and in the config file I need to always have the domain example.com redirect to example.com/test. I tried various methods for achieving this but I always got a redirect error. What is the correct way to do this? nginx.conf snippet: server { server_name example.com www.example.com; location / { rewrite ^.+ /test permanent; } } server { listen 80; server_name www.example.com example.com; location / { root /var/www/apps/example/current/public; passenger_enabled on; rails_env production; } } Thanks!

• Micro sound breaks/interrupts on Windows 7

  - by cand

  Hello all, I've been experiencing strange behavior recently. When listening to mp3 or watching movie or whatever that uses sound, I get micro breaks in sound. It's like it hangs or cuts a fragment for about 0.5s. When I start OS, it's ok, but as time passes it gets worse, to the extent that music is unlistenable being interrupted every 2 seconds. I haven't found any relevance between this behavior and hardware usage, I don't think it's directly related to HDD (or it might be but with significant delay). I have updated soundcard drivers and it didn't help a lot. My system is Windows 7, computer is simple HP laptop, nx7300-Ru374ES with WD Caviar Scorpio Blue hard drive inside and integrated soundcard on it (I can check the model later if it's important). Did anybody encounter such problem ? Maybe it's a common thing on Windows 7 or someone knows how to solve it? Thanks in advance.

• Moving MS Exchange 2007 to another machine

  - by Mustafa Ismail Mustafa

  We have a machine that has been chugging along with the burden of both Exchange and DC and DNS all with SBS 2008. We have a better machine now and I'd like to move Exchange 2007 to that machine and take it off of this machine. In fact, I'm planning on formatting the old machine and get rid of SBS all together because it is making the machine SLOW. How would I go about making the move? I've read on previous versions of Exchange (2000), that all you do is install Exchange on the new machine and then start moving mailboxes one after the other. Well, what about all the different rules we have in place? How do those get moved? How do we de-commission the old exchange and set up the new exchange as the primary one? Come to think of it, how do we have both exchanges recognize each other on the same domain? TIA

• Sudden restart when Ubuntu almost loaded from disc.

  - by Wesley

  Hi all, Here are the specs beforehand: ECS K7SEM motherboard AMD Duron 900MHz 2x 256MB PC133 SDRAM The Best Power MT-500P 500W PSU Integrated graphics No hard drive DVD-ROM - will update with brand & model Now, I was starting up this machine after it was left outside for 3 months in winter weather. (I got this from a friend.) I was able to get it started and tried to load Ubuntu from the DVD-ROM. It was fairly successful and got up to the point when the Ubuntu logo is glowing. However, when Ubuntu was about to go to the main screen, the computer crashed and automatically rebooted. Is there any reason why this is happening? Also, I should mention that when I try to hit Delete on the BIOS screen to go to Setup, it only shows a screen with four lines saying something Novell something... I will edit with exact lines. Should I be resetting the BIOS or something? Thanks in advance.

• Changing SPF (Sender Policy Framework) record for Google Apps

  - by bobo

  My boss asked me to set up Google Apps for a client and basically I have done everything including setting up MX records in DirectAdmin and re-creating the email accounts in Google Apps. I also sent a few test emails to ensure that it actually works and it seems fine. But then I discovered this article talking about changing the SPF record for the domain. http://www.google.com/support/a/bin/answer.py?answer=178723 After reading the introduction I think it would be better for me to change the SPF record according to this article. So I logged in to the DirectAdmin and navigated to the DNS management, and then I found that there's already a TXT SPF record there: v=spf1 a mx a:spf.cabin.com.hk include:gmail.com -all And it looks like it's already including gmail.com, but according to the article it should be: _spf.google.com rather than: gmail.com I dare not to change it before I understand what this record actually means. What would you do with this record if you were me?

• Deployment Workbench no longer available after PXE boot

  - by Patrick

  Our build process revolves around windows Deployment Workbench. Unfortunately this was setup by someone who is no longer with the company, and no-one has ever dared/needed to make any changes. The other day it stopped working. It turns out that one of our build guys started thinking about changing some stuff in it, clicked something and now it no longer works (He is saying now that he right clicked on the 'LAB' entry in 'Deployment points' and hit 'Update', which took some time to run through apparently). The job has fallen on me to resolve and frankly I'm not sure what I'm doing. I was wondering if someone with more experience than me can provide some pointers as to troubleshooting cos I'm feeling quite a lot in the dark here. On the server I have Deployment Workbench up and running (MMC snapin) version 3.0. There is a WDS service that appears to be running ok, as does the tFTPd service. Nothing specific to this in event logs. From the client side; PXE boot works and gets you to the Win PE launch, and it has the correct company logo as the background (proving to me that its loading win PE from the network). WPEINIT runs, and asks for domain credentials, here the team simply put User/Pass/Domain in the boxes and click ok. Normally the build would kick off. Instead they get an error message saying that the \NATBLU01\Distribution$ share isn't available. Checking \NATBLU01\Distribution$ shows that its there and accessible over the network. Security/permissions seem ok, even 'ANONYMOUS LOGON' has read access to that share so I don't see that being a problem. Digging the trace files from C:\MININT\SMSOSD\OSDLOGS\ after an attempt to run the build I can see an error saying much the same - <![LOG[Validating connection to \\NATBLU01\Distribution$]LOG]!><time="16:42:14.000+000" date="03-15-2012" component="LiteTouch" context="" type="1" thread="" file="LiteTouch"> <![LOG[FindFile: The file OSDConnectToUNC.exe could not be found in any standard locations.]LOG]!><time="16:42:14.000+000" date="03-15-2012" component="LiteTouch" context="" type="1" thread="" file="LiteTouch"> <![LOG[The network location cannot be reached. For information about network troubleshooting, see Windows Help.]LOG]!><time="16:42:24.000+000" date="03-15-2012" component="LiteTouch" context="" type="3" thread="" file="LiteTouch"> <![LOG[ERROR - Unable to map a network drive to \\NATBLU01\Distribution$.]LOG]!><time="16:42:24.000+000" date="03-15-2012" component="LiteTouch" context="" type="3" thread="" file="LiteTouch"> BDD.LOG shows much the same. Full copies of the .LOG files can both files be found here : BDD.LOG LITETOUCH.LOG I can get to a command prompt from the Win PE that boots from PXE, however there isn't any network stuff there. IPCONFIG returns nothing so none of the tests I would usually run resolve anything. I'm at a loss frankly. I did wonder if I could perhaps start a new build process but if the change to the DeploymentWorkbench has knocked it offline I don't think I'm going to be able to create a new deployment. Failing that; we do have a deployment point labeled type 'Media' which appears to be a DVD ISO image of one of the builds, but its dated 2008, is it possible to export the network build to .ISO and build from DVD? We are looking at new hardware to run this from anyway (for the impending Windows 7 roll out) so a temporary work round isn't going to be too much of a problem. All assistance is appreciated! EDIT : OK. Got it working again. Solution was close to Newmanth's idea. The problem was that our PE image didn't appear to be connecting the network. I had an older copy of the PE boot.WIM on a stick that I had been using for other purposes. I booted that and correctly got a network connection. Showed a correct internal IP and could ping out etc etc. However I was still getting the same errors in all the logs and in when wpeinit was running. What I did seperately was to update the PE image that DeploymentWorkbench was pushing out to display a different back ground. I wanted to prove that I was working in the correct place. Turns out that I wasn't. I went and looked at the other deployment stuff we had on this machine, Windows Deployment Services was installed and although all the install images are off line the boot image was online, so I uploaded the copy from my stick to that. Booted straight off. And fixed. Working. Yay! For anyone stumbling across this in the future you may find that although your deployment images are located in the DeploymentWorkbench, the Win PE boot image you are launching from is located in the associated Windows Deployment Services images.

• When browsing a specific network share remotely, Windows Explorer continuously jumps back to the parent folder

  - by Evil Pigeon

  I am accessing a specific network path on another domain. It looks something like this: \\CoputerName.OtherDomain.in\c$\Inetpub\Testing\Website\ In under 30 seconds, I am automatically jumped back to \\CoputerName.OtherDomain.in\c$\Inetpub\Testing\ In less time it then jumps back to \\CoputerName.OtherDomain.in\c$\Inetpub\ Then it jumps back to c$ for its final resting place. \\CoputerName.OtherDomain.in\c$\ At first I thought this had to with a faulty keyboard, but this behaviour also occurs when the window does not have focus. It's as if windows thinks that the folder no longer exists (as in someone else has deleted or moved it). This behaviour is not specific to my PC either, it occurs from other machines in the office. Edit: It looks like this issue only occurs from other Windows 7 machines. There are no issues accessing the path from XP.

• SQL Server 2008 lincensing question relating to web servers

  - by Matty Brown

  We purchased SQL Server 2008 Standard licences last year under the server + device CAL licencing model. Since our server has 2 physical CPUs and only 46 clients, this option was by far the cheapest. Now we'd like to be able to query a small number of stored procedures from our Windows Server 2003 Web Edition server, which is in a seperate zone on our firewall. I think SQL Server 2008 Web Edition could be an option to us, but is it possible to replicate/mirror stored procedures and tables to such a server and would we be breaking any rules by doing so? Is this a form of multiplexing? Also, would replication/mirroring work both ways, if we were to want to write back data from the web server?

• Where can I get a metal mug to fit my USB mug warmer?

  - by tjrobinson

  I got one of these for Christmas (this exact model): But it doesn't work very well with normal ceramic mugs as they're too thick and insulated. What I really want is a mug like this that fits well and transmits the heat from the warmer to my drink (so no air gaps or thick bases): Where can I get a mug like the one pictured above from? I like in the UK but don't mind ordering from overseas. Update: I've tried camping mugs but they all seem to be too wide. I will measure the base later and post exact dimensions. I am really after the exact mug shown in the picture, it must exist somewhere?

• switch's mgmt-ip is not remotely reachable.

  - by RainDoctor

  Switch model: Netgear FSM7352PS mgmt-ip: 192.168.1.100/24 Vlan id: 1 (default) There are couple of hosts in this Vlan: 192.168.1.2 (esxi console), for instance. 192.168.1.1 is the firewall/router interface. I can ping 192.168.1.1 and 192.168.1.2 from other vlans, say, 172.31.0.0/24 I can ssh to 192.168.1.2 from 172.31.0.0/24 I can't ping 192.168.1.100 from 172.31.0.0/24 However, I can ping 192.168.1.100 from 192.168.1.2 or from my laptop connected to that vlan (192.168.1.11). I can connect to the web GUI from my laptop when I am in that Vlan. Can anyone shed some light on why I am not able to connect from other vlans?

• Google SMTP settings not sending email

  - by Baboon

  I am having a hard time making the email sending in GitLab to work (changing email in profile settings). My server has exim4, I can tell its working because if I do simple mail() in PHP, it thus sends the email to the recipient. Now, in GitLab seems that it wasn't. So I modified productions.rb to have SMTP settings, and use Google SMTP: config.action_mailer.delivery_method = :smtp config.action_mailer.smtp_settings = { address: "smtp.gmail.com", port: 465, user_name: "[email protected]", password: "hashpassword", domain: "gmail.com", authentication: :plain, enable_starttls_auto: true } I even tried changing the port to 587 and 467 but still it doesn't work. Why is that? Can you please lead me to where I am missing?

• How to Pre-Configure Shared Laptops' Microsoft Outlook 2010 Accounts to Connect to Exchange Server 2007 SP3?

  - by schultkl

  Our IT environment provides 10 shared, Microsoft Windows 7 laptops for an office staff of several hundred people. After checking-out and logging into a laptop with an Active Directory domain account, office staff frequently run Microsoft Outlook 2010. However, the first time office staff do this, Microsoft Outlook 2010 prompts the user to create and configure their local account. This takes just several clicks, as Microsoft Outlook 2010 auto-detects the office staff member's Microsoft Exchange Server 2007 (SP3) account. The problem is: all office staff have to do this on each new laptop they use. Until they do so, some functionality does not work (for example, Microsoft Word 2010 Save & Send fails with error "There was a problem creating the message"). How might our IT department "pre-configure" the shared laptops so office staff can simply log-in and use Microsoft Outlook 2010 functionality without the need to configure a local account?

• Slave/secondary DNS nameserver

  - by user114671

  I'm learning about DNS and have a very basic, generic question about DNS but I can't find an answer anywhere. I have DNS for a few domains set up as follows: - master records with DNS company A - slave records with DNS company B Company A's nameservers are: ns1.companyA.com. ns2.companyA.com. ns3.companyA.com. ns4.companyA.com. ns5.companyA.com. and company B has three slaves: ns6.companyB.com. ns7.companyB.com. ns8.companyB.com. Everything works fine transferring the records between the nameservers and keeping them in sync. But my question is: The registrar of my domain example.com allows me to choose 4 nameservers only. Do I just pick the first 4 for company A, or do I need to include 1 or more of company B's slave nameservers too?

• tracd multiple projects+nginx reverse proxy

  - by Xeross

  I am trying to setup nginx with a reverse proxy to tracd, however I only want to use 1 tracd. Now first here's my config for this domain server { listen 80; server_name bugs.XXXXXXXX.com; access_log /var/log/nginx/XXXXXXXX-bugtracker.access.log proxy; location / { rewrite ^/bugtracker/(.*)$ /$1; rewrite ^/bugtracker$ /; proxy_pass http://127.0.0.1:81/bugtracker/; proxy_redirect default; proxy_set_header Host $host; } location ~ /\.ht { deny all; } } As you can see there's the rewrite rules, because for some reason all the urls that tracd spews out are like /bugtracker/something. Now this is indeed caused by tracd just sending urls like it normally should however trac is at bugs.XXXXXXXX.com/ and not at bugs.XXXXXXXX.com/bugtracker. So how can I make tracd/trac display the (In this case) correct urls ?

• High availability for Windows Service under Windows Server 2003

  - by empi

  Hi. I have a following situation: I need to deploy a windows service that listens for incoming request on tcp port (basically WCF service). I have a High Availability requirement - the service must be deployed on two servers and if the service stops (only the service, not the whole server) on one server, all the requests must be redirected to the second one. For me it looks like a basic failover scenario. How can I achieve this on Windows Server 2003? Should I use Microsoft Cluster Service or Network Load Balancing? The important part is that the process of swapping the servers should not concern the clients (the client must see only single address / single host or domain name). Thanks in advance for help.
