I have a strange issue with an Active Directory profile.

When the user logs onto a machine with his profile, the whole machine becomes incredibly slow and unresponsive, with programs hanging and taking an age to load everything.

If I log into the same machine with any other profile nothing happens.

I took a look at his original profile, any start up programs, login scripts, etc and could not see what could be causing this. The machine is not running out of memory or CPU. Nothing strange is appearing in the event log and I can see nothing running under his profile which may cause this.

So I created the user a new profile to test this on and exactly the same thing happens on the first login. The only thing which would of been carried across is the security groups the user is assigned to, yet I have other users with the same groups who do not experience these issues so I am now at a complete loss on where to go next!
