Do not disable IPv6 on Windows SBS 2008

emb — Wed, 05 Aug 2009 03:32:56 +0000

I had a nasty scare today after rebooting a Small Business Server 2008 Premium box for a client of mine. At some point during the migration I was annoyed with seeing the IPv6 addresses in a number of the logs I was looking at so I just went ahead and removed IPv6 from the networking properties. After rebooting the server a few days later to finish the cleanup of the old domain controller the server didn’t come back up correctly. It sat at “Applying computer settings..” for at least 30 minutes (I didn’t wait any longer) and didn’t start all of the services. I was able to get into the event log from a remote server and saw a lot of complaining about mad.exe not finding the right topology. I figured removing Exchange 2003 and demoting the original SBS 2003 server hosed me. After a quick google search (honestly, how did I work before google?) I found a bunch of articles that talk about the problems with just disabling IPv6:

Issues Adter Disabling IPv6 in SBS 2008 (technet)

After booing into safe mode and enabling IPv6 the server came right up and I was able to stop sweating and go to bed. I’m just going to leave that on for now.. :)

ODBC Connection With Virtual Center 4.0 on Windows 2008 x64

emb — Wed, 22 Jul 2009 18:50:22 +0000

There are a number of articles that say the 32-bit ODBC administration tool is found under c:\windows\system32\odbcad32.exe but this still only configures the 64-bit ODBC drivers. The ODBC administration tool to use is c:\windows\syswow64\odbcad32.exe and the “sql native client”. After this the Virtual Center installation will find the connection and proceed.

Adjusting SCSI Target ID in ESX Server 3 with iSCSI

emb — Wed, 26 Sep 2007 21:01:55 +0000

I had an issue with an iSCSI target LUN not being formatted as VMFS in ESX Server 3.0.X. The problem turned out to be on my side, but I ended up with a number of blank SCSI Targets under VI -> Configuration -> Storage Adapters. My SCSI Targets jumped from SCSI Target 2 to SCSI Target 9. This was not an ideal situation as I want all of the members of the DRS/HA cluster to have the same configuration. The way to fix up the SCSI Targets involves adjusting some of the configuration files on the ESX Server itself. First you need to move any and all running VMs off of the host you’re going to be working on and put it into Maintenance Mode.

Log into the service console as root.
cd /var/lib/iscsi and there are two control files there: vmkbindings, vmkdiscovery
temporarily disable iSCSI: esxcfg-swiscsi -d
kill the iSCSI software: esxcfg-swiscsi -k
edit both the vmkbindings and vmkdiscovery to remove the LUNs that are no longer valid. You can change the target ID as well if you want to move that around.
start iSCSI back up: esxcfg-swscsi -e
wait about 30 seconds and do a rescan from the command line: esxcfg-swscsi -s
once you do that you can go into the VI Client and rescan the Storage Adapters. If this looks right now you’re all set.
take the server out of maintenance mode and move a VM to the server to make sure it is working correct

That’s it! Good luck, this saved me a decent amount of time and I wasn’t able to find this information in the forums or on the interwebs.

As if you needed another reason to NOT watch the view..

They asked the new host of The View is she thought the world was flat. She honestly doesn’t KNOW if the world is flat or not. Watch her wiggle out of this one. Unbelievable. How can someone be this stupid?

Invalid Response

emb — Wed, 05 Sep 2007 17:07:51 +0000

This has really just been my luck so far this week. I turn on our new Avocent MergePoint 5300 to start the configuration. Go into the configuration via the console port:

1:Summary
2:Network config
3:Set date and time
4:Set admin password
5:Reboot
6:Power off
7:Roll back the version
8:Security config
9:Debug Log
10:Restore to Factory Defaults
0:Exit
Please select [0 - 10]:

Fair enough, right? All I need to do is set up the IP address so I can jump into the configuration website so I select “Network Config”.

Apparently there is no known valid response. How does a product leave QA in this state? I already hate this thing and I haven’t even set it up yet.

Set “no default route” for OSX Tiger VPN Client

This should be more obvious than it is: Launch “Internet Connect”, select “Options…” from the “Connect” menu and deselect “Send all traffic over VPN connection”.

Princess Bride is Twenty Years Old

One of my favorite movies (save your jabs for the comments section) Princess Bride is twenty years old. That makes me feel, well, old I guess. I saw this on Digg and the “Then and Now” pictures come via ABC News.
