seems like the problem ...I have been experiencing also. Virtual Center just decided to die(stop working)///service would not work.
When I try to manually start it. I get this error: windows could not start the vmware vitualCenter server on Local computer. For more information, review the system event log. If this is a non-microsoft service, contact the service vendor, and refer to service-specific error code 2.
Most of my messages appear on this thread:

I also tried changing the the odbc connection to named pipes / window authentication and every combination their of.....hmmmm very discouraging.
I will attempt to download this upgrade....but I hear from VMWARE that this version has a bug(2.5 U2) in it and the patch may or may not be released as of 2008-08-14.
Thanks,

OK-UPDATE and fixed at 7:16pm on 8/14/2008
VMWARE VIRTUAL CENTER UPDATE 2 (2.5 Update 2 - 7/25/2008) build 104263 seemed to fix the problem. This version also upgraded the database(in other words I choose not to overwrite the old database) and it seemed to work just fine. So after 3 hours of research and trying to use the reinstall using the current version I had previously downloaded. This new update did the trick.

OK-UPDATE 2008-08-15 at 9:00am in Louisiana
To NOTE: Virtual Center (Virtual Infrastructure) does not have a bug in the latest version on the downloads page(version 2.5 U2) the bug is in the ESX hosts. The bug was reported in the ESX version 3.5-U2-103908. And Yes I have this version which I will be patching over the weekend....whether the problem I recieved in the Virtual Center is related, I do not know....but it was quite a coincidence. Any how, the direct problem that I was experiencing with virtual center is now corrected(to note: make sure you choose to upgrade the Virtual Center Database(not overwrite) and the whole process takes 15 minutes. I am not going to try and VMOTION or anything else until the faulty ESX box (which has 3.5-U2-103908 installed) has the patches applied.
