After about the 2nd or 3rd reboot of a newly imaged optiplex 390 the 11.2 zen agent service fails to start. It takes about 5 to 10 minutes for the desktop to load after logging in. Then if I try to double click the zen agent icon I just see a white screen and a green progress bar in the bottom right hand corner.
When I try to close this window I see the error

"The Zenworks service does not appear to be running. Please restart the service and try your request again. System.Threading.ThreadExceptionEventargs."

Restarting the various zen services in windows doesn't help. Upgraded the bios of the desktop. All the drivers seem to be up to date. All windows updates are applied.

I also reimaged the desktop and it did the same thing.

I have an SR open but haven't heard anything yet, just thought I'd see if anyone else had any of these issues.
