Shell Does Not Start After Logon

• Microsoft Windows NT Server version 4.0
• Microsoft Windows NT Workstation version 4.0

SYMPTOMS

After a clean installation of Windows NT, you may be able to log on, but the shell may not start.

NOTE: Typically it will be a user, not the administrator, who sees this behavior.

CAUSE

Security was inherited from the root, which does not allow a user access to %systemroot% because security has not been set on %systemroot%.

RESOLUTION

Using File Manager's or Windows NT Explorer's security dialogue box, set security on the %systemroot% directory such that "Everyone" has RX permissions, and clear the "Replace Permissions on Existing Files" check box. Also, clear the "Replace permissions on Subdirectories" check box.

Alternately, "Everyone" can be replaced with the users you want to be able to log on.

If the shell does not start for any account, you must use one of the following methods:

• Reformat the drive and reinstall.
• Boot from another installation of Windows NT that does not exhibit this behavior and change the security on the volume as indicated for %systemroot%.
• Install onto another volume that does not have such security.

MORE INFORMATION

This problem does not occur after an upgrade from a previous version or if the volume installed upon is formatted during the install process.

Typically, this problem is seen when the permissions on the volume on which the system was installed grant access to Administrators and System, but "Everyone" has been removed.
