I have an odd situation here.  One of my PDM users; not using SolidWorks, will get kicked out of PDM after exactly 8 hours.  This isn't 8 hours of inactivity, he could be in the middle of checking in documents and he will get the login box.  If he initially logs into PDM at 7:32AM, at 3:32PM he will get prompted to login again.  

Any ideas??
