I've imported the Windows GroupPoily directory into "Network Loacation
of existing Group Policies", but when I try to "Edit Policies" I get a
error message:

"The snap-in below, referenced in this document has been restricted by
policy. Contakt your administrator for details. Group Policy."

I know that in the policy files I have activated that option, but I'm
wondering if it is possible to Edit the policy files, without activating
them first.
