I keep getting the following errors when trying to scan for updates for one of my Hosts:
VmwareUpdate manager had a failure.
Except for this one host, all other ESX servers respond fine. Firewall port for Update Manager opened in all ESX Servers.
I tried to search but nothing came up for the error message. Has anyone seen this before?
I had this problem. Had just installed ESX 3.5, added the server to VC but couldn't scan the server for updates - kept failing. Noticed that the time was way off (more than 3 years). Reset the clock, re-tried the scan and it worked.
