Seems that the file is a ghost...
I did like you asked me to, started the CMD with and administrative permissions, and typed the command: C:\Users>dir /S vm_ssoreg.log, and suprise suprise...nothing, nada...
(as always i attached a screen shot).
I looked at the KB you sent me, and after doublechecking the my dns, i can assure you that everything is ok.
- i can ping the vcenter server with IP.
- i can ping the vcenter server with the hostname.
- i can ping the vcneter server with FQDN.
-i checked with nslookup the resolving, and indid it connects to my DC.
-the clocked is synchronized, no problems there.
And as always, the KB is asking me to look for the vm_ssoreg.log, but as we all know, there's no such log.
I thought i'll try to uninstall the vmaware single sign on from the add/remove programs, and reinstall it again....goo or bad idea?
