We had been having a bunch of blue screens (stop 0xC4) on a perticular server and all of testing and debugging got us no where.<br /><br />So we ran verifier to check for all drivers on this server. As soon as we finished configuring verifier.exe and gave the server a reboot it blue screened with a STOP 0x000000D5, but this time the culprit came out. It was cdprobe.sys running on this windows 2003 server as part of Symantec's Centennial Discovery Client Agent. We disabled it and the server has been running fine since then.<br /><br />So how do you use Verifier.exe ???<br /><br />Here are the steps to enable Verifier.<br /><br />Start > Run, type <strong>Verifier </strong>and hit enter.<br /><br />Select the radio button for <strong>Create custom settings (for code developers)</strong>, click <strong>Next</strong><br /><strong></strong><br />on this screen click <strong>Select individual settings from a full list, </strong>click<strong> Next </strong><br /><strong></strong><br />Tick the first three check boxes of <strong>Special Pool, Pool Tracking, Force IRQL checking</strong>, click <strong>Next</strong><br /><strong></strong><br />Check the box for<strong> Select driver names for a list</strong> and click<strong> Next</strong><br /><strong></strong><br />In this screen, sort by Provider and then select all the Non-Microsoft drivers. Click <strong>Finish. </strong>It will ask you to reboot.<br /><br />If your server has a bad driver it will bluescreen and display the name of the problematic driver (see screenshot below).<br /><strong></strong><br /><br /><a href="http://picasaweb.google.com/lh/photo/-8L3inum6SB13wAF6M7YEA?authkey=Gv1sRgCO_O4rXi9J288wE&feat=embedwebsite"><img src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEjmMWvg6Ko6p5N9Qzq3hSgfi14PBKxfpgBDotUm0x8dfyDSRFgvKWCEvYNVNu4DK0qqfDaQIVxts0wr1_K6xLsZqczm4BqxyE6BTNSQ_W9uNJ7wHcJGJVcPeAcU-wmOHsQ5z3i05jHHiATr/s800/cdprobe.jpg" /></a>Ranjanhttp://www.blogger.com/profile/12712361513165044433noreply@blogger.com2tag:blogger.com,1999:blog-5479021421620906624.post-66982879445691771252009-05-13T16:01:00.000+10:002009-05-13T21:59:28.207+10:00DFS Replication with Windows 2003 R2 , eventid 6012<div>This morning got a new DFS built going and after getting all the config work on it, tried to get the Folder replication to start but got this rude error.<br /><br /><em><font size="2">Domain: The Active Directory schema on domain controller dc1 cannot be read.

<br /><div>Our Domain Controllers were running Windows 2003 while our file servers had moved up to Windows 2003 R2. So the solution was simple, backup your domain controller, get the CD 2 of the Windows 2003 R2 and run adprep.exe /forestprep from it. We did that and voila DFS replication working happily.</div>

You tried to SSH to it and login as root. What happened?</div><div>It didn’t work, did it?</div><div>The firewall allows it, right? (yes) You can login to the physical server console with the same username & password, right? (yes) But it still doesn’t work, does it?</div><div>Let’s find out how to fix it….</div><div>To allow the root user to login to a VMware ESX Server over the network using SSH, do the following:</div><div>1.<span class="Apple-tab-span" style="white-space:pre"> </span>Go to the service console on the physical server & login </div><div>2.<span class="Apple-tab-span" style="white-space:pre"> </span><span class="Apple-style-span" style="font-family: 'courier new';">vi /etc/ssh/sshd_config</span> </div><div>3.<span class="Apple-tab-span" style="white-space:pre"> </span>Change the line that says PermitRootLogin from “no” to “yes” </div><div>4.<span class="Apple-tab-span" style="white-space:pre"> </span>do service sshd restart </div><div>And your problem is solved…</div><div><br /></div><div>OR from console run this:</div><div> </div><div><span class="Apple-style-span" style="font-family:'courier new';">mv /etc/ssh/sshd_config /etc/ssh/sshd_config.orig</span></div><div><span class="Apple-style-span" style="font-family:'courier new';">cat /etc/ssh/sshd_config.orig | sed 's/PermitRootLogin no/PermitRootLogin yes/g' > /etc/ssh/sshd_config</span></div><div><span class="Apple-style-span" style="font-family:'courier new';">service sshd restart</span></div><div><br /></div><div>However, having said the above, it is not a good security practise to allow direct root level login over the network even if its using SSH. I prefer to add a regular users, SSH to the server using that account and then SU - to get to root.</div><div><br /></div><div>Another recommendation is to use one non-root group for VM admins and add operator/admin users there. To create that group, enter the following command: </div><div><span class="Apple-style-span" style="font-family:'courier new';">groupadd -g 7777 vmadmins </span></div><div><br /></div><div><div>To create an account for the new admins, enter the following commands: </div><div><br /></div><div><span class="Apple-style-span" style="font-family:'courier new';">useradd -c "ESX server operator" ESXOps</span> </div><div>Create a single userid, which will be able to operate all of the VMs. </div><div><br /></div><div><span class="Apple-style-span" style="font-family:'courier new';">useradd -g 7777 johndoe</span> </div><div>Create a userid, and make groupid 7777 (vmadmins) as its primary group. </div><div><br /></div><div><span class="Apple-style-span" style="font-family:'courier new';">useradd -g 7777 -c "Joe Blog" joeblog2</span> </div><div>Create a userid, and make groupid 7777 (vmadmins) as its primary group. </div><div><br /></div></div>Ranjanhttp://www.blogger.com/profile/12712361513165044433noreply@blogger.com0tag:blogger.com,1999:blog-5479021421620906624.post-24527640209526439662009-01-21T22:16:00.000+10:002009-01-21T22:42:42.365+10:00The curious case of missing DLLOne fine day the SAP system on our development server did not come back after an overnight offline backup. The guys tried a lot but it wouldn't start. Trying to start it from the command line told us that the <span class="Apple-style-span" style="font-weight: bold;">mfc71u.dll </span>was not present in C:\WINDOWS\system32. We restored the file from last nights backup and the SAP system started perfectly.<div><br /><div>Now on a regular PC generally nobody goes in C:\WINDOWS\system32 and deletes files on a fancy and this was a heavily restricted SAP server with only the SAP and the OPS team having access. System logs didn't not indicate any unwanted activity. The only activity was the installation of Symantec EndPoint Protection Manager client, but this was a week back. Also this deployment had been tested on 5 test server previously without any issue.</div><div><br /></div><div>The server's application event log indicated that Symantec EPM installed successfully. Still I got the boys to check the log created by Symantec EPM. This is what we found in the installation log. </div><div><br /></div><div><div><span class="Apple-style-span" style="font-size: small;"><span class="Apple-style-span" style="color: rgb(255, 0, 0);">Info 1603.The file C:\WINDOWS\system32\mfc71u.dll is being held in use by the following process: Name: sapstartsrv, ID: 10572, Window Title: (not determined yet).

Error 2020 indicates Paged Pool and 2019, NonPaged Pool. This doesn’t mean that the Server Service (srv.sys) is broken or the root cause of the problem, more often rather it is the first component to see the resource problem and report it to the Event Log.</p> <p>I installed <a href="http://support.microsoft.com/kb/177415">Poolmon</a> which told me that Thre is the largest consumer of memory</p> <p><a href="http://lh4.ggpht.com/_NKNJo40HtEA/SW3sWpv8RjI/AAAAAAAAABk/NFvcWJgkLUc/s1600-h/Poolmon%5B4%5D.jpg"><img title="Poolmon" style="border-top-width: 0px; display: inline; border-left-width: 0px; border-bottom-width: 0px; border-right-width: 0px" height="113" alt="Poolmon" src="http://lh4.ggpht.com/_NKNJo40HtEA/SW3sXaJVSPI/AAAAAAAAABo/cSPnnSl8Dnc/Poolmon_thumb%5B2%5D.jpg?imgmax=800" width="666" border="0" /></a> </p> <p>So what's "<strong>Thre"</strong> ?</p> <p>Thre - nt!ps - Thread objects</p> <p>Note, the nt before the ! means that this is NT or the kernel’s tag for Thread objects.

Even the page for getting the evaluation keys was hammered and I couldn't get keys.<br /><br />For a company that's pushing cloud computing and web services and trying so hard to prove that they're ready to move off the desktop and onto the web, today's Windows 7 mess proves Microsoft is still needs to work out about how to do stuff online to be taken seriously.<br />They could have looked at <span class="blsp-spelling-error" id="SPELLING_ERROR_0">Ubuntu</span> who are always seeding a torrent of their main <span class="blsp-spelling-error" id="SPELLING_ERROR_1">distro</span>.<br /><br />So even the biggest and the best do get it wrong sometimes.Ranjanhttp://www.blogger.com/profile/12712361513165044433noreply@blogger.com0tag:blogger.com,1999:blog-5479021421620906624.post-29160680695463435232009-01-09T13:24:00.000+10:002009-01-09T13:28:02.136+10:00Windows 7Windows 7 goes to public beta today.

Here is one that made me run in circles for days on end.<div><br /></div><div><b>Windows Server 2003 R2 SP2 stuck at "applying computer settings"</b><br /></div><div><span class="Apple-style-span" style="font-weight: bold;"><span class="Apple-style-span" style="font-weight: normal; ">We had patches applied to this server and rebooted. It hung at applying computer settings. Rebooting it in safe mode got stuck at loading drivers. Funny thing was if we let the server boot overnight, it eventually came up after about 10 hours but was <span class="blsp-spelling-corrected" id="SPELLING_ERROR_0">extremely</span> sluggish.</span><br /></span></div><div><br /></div><div>On the net there were some posts about <span class="blsp-spelling-error" id="SPELLING_ERROR_1">APC</span> software doing it, but we did not use <span class="blsp-spelling-error" id="SPELLING_ERROR_2">APC</span> here. Digging at past Change Requests (yes it does come in handy) it was mentioned that the OPS guys had requested the SAN team about 1.5 TB of extra disk space for this <span class="blsp-spelling-error" id="SPELLING_ERROR_3">DFS</span> server. Got the SAN guys to remove the newly presented <span class="blsp-spelling-error" id="SPELLING_ERROR_4">LUNs</span> as they had not been assigned to the <span class="blsp-spelling-error" id="SPELLING_ERROR_5">DFS</span> yet. </div><div><br /></div><div>Rebooted the server without the newly assigned <span class="blsp-spelling-error" id="SPELLING_ERROR_6">LUNs</span> and it came back fine. Got Hitachi involved and long story short, turns out that one of the <span class="blsp-spelling-error" id="SPELLING_ERROR_7">LUN's</span> was from a past <span class="blsp-spelling-corrected" id="SPELLING_ERROR_8">decommissioned</span> server and the locks from the <span class="blsp-spelling-error" id="SPELLING_ERROR_9">LUN</span> had not been cleared. (the disk had not been formatted before being deleted and the <span class="blsp-spelling-error" id="SPELLING_ERROR_10">LUN</span> removed). So when the <span class="blsp-spelling-error" id="SPELLING_ERROR_11">LUN</span> was presented to this server it confused <span class="blsp-spelling-corrected" id="SPELLING_ERROR_12">Window's</span> Disk Management and locked it up. </div>Ranjanhttp://www.blogger.com/profile/12712361513165044433noreply@blogger.com0
