I am asking this because before the introduction of SEP in my environment, we had never seen the following error "The trust relationship between this workstation and the primary domain failed" I was working with a machine and tried to push SEP RU3 Client onto it, and I was unable to get to it. When I attempted to access it via the root share I got There are currently no logon servers available to service the logon request. The client was on an older version and I chose to add it to a group that had RU3 ready to go and push it out remotely. The machine had been on the domain for a long time and there were no other changes to the PC outside of an attempted SEP upgrade.
Never seen this before. Disable the firewall, see what happens.
I already removed and re added to the domain. The next time it happens, I will get more specifics about it.
I found a thread with the same error message

Doesn't look to apply to you though?
Interesting, we never had this happen on ANY XP machine ever. The UAC is turned off and the local admin is enabled. So this narrows it down to pretty much Windows7 for me. This also never happened with any SAV client or instalation.
The "Administrator" is disabled, but that is becasue we use another account and disable to built in one.
