You nailed it. I suspected .net updages, since one hosed my digital audio production software a year ago, but didn't see anything on that page when i was there a couple days ago and nothing in Google that i could find. Good eye.
This SOLUTION worked perfect for me as I couldn't find an update to my build of Vsphere client since I have XP.
"I got the above error today after running Windows Update on my XP VM a
few days ago. A quick search showed that the error is caused by a
Microsoft update to the .NET framework. To resolve it, remove update
KB980773 (Add/Remove programs, make sure “Show Updates” is checked;
KB980773 is under “Microsoft .NET Framework 2.0 Service Pack 2″). I
removed it and was able to log in without problems. "
It seems the solution is as crankinrankin to remove the KB980773, or the other option will be to download the latest vSphere client as VMware has already resolved that in the latest client. You can found more details on this at my post:
vSphere Client Error parsing the server “SERVER IP” “clients.xml” file. Login will continue, contact your system administrator.
I hope this help some one, if it does please reward points.
