I saw a few discussions about Terminalservices Policies with Zen 6.5.
The only think you will not find is de terminal services policies for
creating default printers, lpt, com port etc.

We upgraded our tree to Zen 6.5 (from 4.01) and use terminal services
policies on Windows 2003.

We use Grouppolicies from w2k3
We use roaming profiles.
We use dynamic local user
Is fast enough.
It works fine.

The documention from Novell is VERY VERY bad about this subject. They
have to update this. Maybe someone could ask.
