If the privileges you have assigned a Windows NT User become inadequate for your needs, or if the user or group no longer requires access to certain services, you may wish to change or delete the Windows NT User account privileges.
To modify a Windows NT User account
From the Setup menu, choose Security. Click the NT Users tab.
In the User List box, select a Windows NT User.
Select or clear the services you wish to grant or deny. If you wish to deny access entirely, click Remove to remove the Windows NT User account.
Clicking Remove does not delete the Windows user or group from the your network's Windows security database. It only removes the user account from your list of Timbuktu Pro authorized users.
Click OK to save your changes and close the Security dialog box.
