After you install Internet Explorer version 6 or version 6 Service Pack 1 (SP1) on a Windows 2000-based computer that is running Terminal Services, if the "Important URLs & Favorites and Links" Windows 2000 Group Policy is enabled, Index.dat files may not be deleted on the server when a user logs off from a Windows 2000 Terminal Services client. This problem may occur even though the "Delete cached roaming profiles" group policy is enabled. This problem does not occur in Microsoft Internet Explorer versions 5.0 and 5.01 or if the "Important URLs & Favorites and Links" Windows 2000 Group Policy is not enabled.

Cached profile folders are created but not completely deleted because three Index.dat files cannot be deleted in three different subfolders. Therefore, every time a user logs on and off, new folders are created on the computer that is running Terminal Services in the user_name, user_name.000, user_name.001 format. A new folder is created for each user. These folders quickly fill the hard disk of the computer that is running Terminal Services.
