We have had several PC's in the last few months experience this problem. For no good reason the user will log into their machine and be running under a temporary profile. Normally, just shutting the machine down for a minute fixes the issue, but this doesn't always work for us. The machines are part of an Active Directory, Server 2003 domain. Just lately we've started to have a whole bunch of machine have this problem. We aren't sure if an update released by Microsoft has caused this or not. Anyone have an idea what could be causing this? Their normal profile is not corrupt. We normally just log in as the local admin and delete the temp profile(s) - there can be several sometimes. It doesn't matter if its a laptop or desktop.
