Hello mittim, thanks for your prompt answer.
on VC, I cannot see any entry in event viewer or in the events seen from the vsphere client. Moreover, if I look at the events related to the desktop I'm analyzing, I can see only the events related to a successful turn on (included the one I performed manually), but no events regarding any error.
Looks like the connection server doesn't contact VC at all...
is there any other place I can look into? logs somewhere?
