with xp/2003 you could turn on the userenv.log, but apparently this
does not work with windows 7
(http://social.technet.microsoft.com/Forums/en/winserverGP/thread/a9b36648-aa9f-4ff7-b23f-c1123b7984e9);
so check the event log of the client and/or use process monitor from
sysinternals to get a log of what is going on it. See this

for inspiration.

good luck!
