My Folders access issue

[cognosun]

We are using cognos 8.4

There is a user group in which every one can access the 'My folders'  except one user.

Even that user can able to access 'My folders' in another workstation.

Is there any link between 'My Folders' tab, Users 'Web browser' and other Workstation specific things ?

Below is the warning message the user is getting while accessing My Folders :

"The page cannot be displayed. The loaction may have been deleted or you may not have sufficient privileges to see it"

make sure site is in Local Intranet zone; make sure credentials are getting passed in IE/FF

PC is in the domain, or outside?  User has logged into domain? 

Sounds like credentials getting stripped away, either by IE settings, or by a firewall, switch, router
