Remove a Server Running NPS or Change a Server Shared Secret for a Centrally Stored RD CAP
Applies To: Windows Server 2008 R2
If you are changing the shared secret for a server that is running Network Policy Server (NPS) on which a central Remote Desktop connection authorization policy (RD CAP) is stored, keep in mind that you must use the same case-sensitive shared secret that you specified when configuring the RD Gateway server as a RADIUS client on the central server running NPS.
We also recommend that you do the following:
Generate long shared secrets (more than 22 characters) comprised of a random sequence of letters, numbers, and punctuation.
Change the shared secret often.
Membership in the local Administrators group, or equivalent, on the RD Gateway server that you plan to configure, is the minimum required to complete this procedure. Review details about using the appropriate accounts and group memberships at http://go.microsoft.com/fwlink/?LinkId=83477.
