Upgrade VMware ESX 3.0.1 to ESX 3.0.2

Pretty easy & smooth process to upgrade from VMware Infrastructure ESX 3.0.1 to VMware ESX 3.0.2. Since I'm running my systems off a SAN and using VMWare vmotion all I needed to do was put my first ESX server in maintenance mode and shut it down. This automatically moved all my running VM's via vmotion over to the other ESX server. I then put in the 3.0.2 install / upgrade CD and booted from it. CD Upgrade went pretty quickly, approx 10 minutes and then rebooted the system. After reboot my Virtual Center picked the system with no problems and I turned on a test machine to make sure it was working ok. I then moved over a couple production VM's without problems.

Since the upgrade appeared to work just fine I repeated the process on my second ESX server.

There are multiple accounts with name cifs/ of type DS_SERVICE_PRINCIPAL_NAME

I've been having the following error logging on my domain controllers about every hour for quite some time now and finally got around to drilling down to figure it out.

Type: Error
Event: 11
Date Time: 8/29/2007 7:46:33 AM
Source: KDC
ComputerName: DC2
Category: None
User: N/A
Description: There are multiple accounts with name cifs/ of type DS_SERVICE_PRINCIPAL_NAME.

After a little research and lots of luck... I decided to use ldp.exe to do a quick search of the (serivce
principal=* What do you know... it came up with 2 accounts sharing that name. I quickly found the one that was a problem and deleted it. It turns out somebody put an image on a few machines without first pulling the source from the domain... not a good idea.
