Windows 7 logs out immediately after log in

Hi all: I don't know what is causing this issue, but this is a good place to start. Our system in a HP workstation running 64-bit Windows 7, Novell Client 2 SP3, ZCM 11.2.3 and iprint 5.90. When I attempt to log in via the Novell client the log in proceeds normally but then logs me out. If I remove the Novell client the problem goes away, reinstall and it comes back. I can log in to the local machine, and then manually log in with the Novell client and ZCM client. I came across a Microsoft knowledgebase article concerning user environment settings, but checking these shows no problem.

So, I am sure someone has run into this before. Can you help me out? Thanks, Chris.
