I cant get the option, "UpgradeExchange Virtual Server"on one of my EVS servers. The other EVS upgraded successfully. We have a 3 node cluster Active/Active/Passive and 2 virtual servers EVS1 and EVS2. EVS 2 upgraded successfully, All nodes now have SP2 binaries, but system manger still shows SP1 for EVS1. can anyone help please?

Did you carefully follow this doc? http://support.microsoft.com/kb/328839

Yes. At step 11 I got Upgrade Exchange Virtual Server on EVS2 but nothing on EVS1, even whenI upgraded the last node in the cluster I still didn't get the option. No errors logged in event viewer.

Nothing in app or system log doesn't give me much to go on. Sorry.
