Permissions on Temp Folder Are Set Incorrectly When FlatTemp Is Enabled

PSS ID Number: 255523

Article Last Modified on 10/3/2003

The information in this article applies to:

  • Microsoft Windows NT Server 4.0 Terminal Server Edition SP4
  • Microsoft Windows NT Server 4.0 Terminal Server Edition SP5

After you run the flattemp /enable command on a Terminal Server with either Service Pack 4 or Service Pack 5 installed, the Temp folder permissions are changed when a user logs on to the Terminal Server console. The existing permissions are replaced with:

Username [FC]
Administrators [FC]
System [FC]

The correct permissions for the Temp folder should be:

Creator Owner [FC]
Everyone [Change]
Administrators [FC]
System [FC]

Attempting to access the Temp folder in a Terminal Server session results in an "Access denied" error message.


The local console logon process ignores the FlatTemp registry setting and sets the permissions on the Temporary folder to allow access only to the logged-on user.
