Hi LLXX, Barring the system and hidden attribs, I have narrowed it down to having a domain logon with admin rights on this computer, my XP Pro system. If I'm logged in with a domain login (with Admin rights and also Domain Admin rights) I cannot see the OLKxxx or Content.IE5 folders. If I'm logged in locally with the local Admin account I can see those folders in anyones profile folders. So it seems like this is something imposed by XP to secure those folder from a Domain Admin?!?! Very odd as Domain Admins should have full Admin rights. This XP Pro install is 2 weeks old, free of spyware/adware or viruses. Thoughts?
