Managing NPS servers across your organization means providing NPS server availability, with approved and consistent network policies configured across your NPS deployment.
When you manage NPS servers, you ensure that RADIUS clients have access to the servers, that NPS servers have permission to access your user account databases, and that RADIUS traffic is sent and received on the same UDP ports.
In addition, you can synchronize server configurations in whole or in part by using Netsh commands for NPS.
The following tasks for managing NPS servers are described in this objective:
Configure NPS on a Multihomed Computer
Configure NPS UDP Port Information
Disable NAS Notification Forwarding
Export an NPS Server Configuration for Import on Another Server
Increase the Number of NPS Concurrent Authentications
Interpret NPS Database Format Log Files
Register an NPS Server in Another Domain
Register an NPS Server in its Default Domain
Unregister an NPS Server from its Default Domain
Verify Configuration After an NPS Server IP Address Change
Verify Configuration After Renaming an NPS Server
NPS provides three tools that you can use to administer NPS: the NPS console, the NPS Microsoft Management Console (MMC) snap-in, and the Netsh commands for NPS (netsh nps).
The following procedures show how to manage NPS using these tools:
Enter the Netsh NPS Context on an NPS Server
Manage an NPS Server by Using Remote Desktop Connection
Manage Multiple NPS Servers by Using the NPS MMC Snap-in
Configure the Local NPS Server by Using the NPS Console
You can use this procedure to enable the Remote administration exception in Windows Firewall with Advanced Security.
You can use the Network Policy Server (NPS) Microsoft Management Console (MMC) snap-in to manage both the local and remote NPS servers. To manage remote servers, however, you must first enable the ^ exception on the firewall of the NPS server that you want to manage.
To complete this procedure, you must be a member of the Administrators group.
You can use commands in the Netsh NPS context to show and set the configuration of the authentication, authorization, accounting, and auditing database used both by NPS and the Routing and Remote Access service. Use commands in the Netsh NPS context to:
Configure or reconfigure an NPS server, including all aspects of NPS that are also available for configuration by using the NPS console in the Windows interface.
Export the configuration of one NPS server (the source server), including registry keys and the NPS configuration store, as a Netsh script.
Import the configuration to another NPS server by using a Netsh script and the exported configuration file from the source NPS server.
You can run these commands from the Windows Server 2008 command prompt or from the command prompt for the Netsh NPS context. For these commands to work at the Windows Server 2008 command prompt, you must type netsh nps before typing additional commands and their parameters.
There are functional differences between Netsh context commands in the Windows Server 2003 family and Netsh commands in Windows Server 2008.
To perform this procedure, you must be a member of the Administrators group on the local computer.
