VMware Update Manager

[Sudarshan_Bhart]

I am trying to patch ESXi 5.5 4345813 with vCenter Server 5.5 3721164. But getting error during scan. Its working fine with another ESXi 5.5 2068190.

"The host returns esxupdate error code:99. An unhandled exception was encountered. Check the Update Manager log files and esxupdate log files for more details."

Can you attach the esxupdate.log from the faulty host? And the following three blog post may helps you:
