New XP SP1a install - works fine
install Novell client 4.90 sp2 - works fine
install ZEN agent - works fine
enable policies - works fine - wow this is really going to work this time
install NDPS printer - takes 90 sec to logoff or shutdown
remove printer - still take 90 s to shutdown
remove ZEN agent - takes 5 sec to shutdown
install ZEN agent - takes 90 sec to shutdown

note there is still no printer installed.

It seems the NDPS printer install has caused a problem with the ZEN

There is this IGMP V2 Membership Report stuff in the packet stream when
the ZEN agent is installed. Its not there without the agent and shutdown
is fast.
