- Click Start, type regedit in the Start Search box, and then press ENTER.

The LocalAccountTokenFilterPolicy entry in the registry can have a value of 0 or 1. These values set the behavior of the entry as follows:
0 = build a filtered token
This is the default value. The administrator credentials are removed. These credentials are required for remote administration of the print drivers.
1 = build an elevated token
This value enables the remote administration of the print drivers on a server within a workgroup.
