Disable NAS Notification Forwarding
Updated: February 29, 2012
Applies To: Windows Server 2008, Windows Server 2008 R2, Windows Server 2012
You can use this procedure to disable the forwarding of start and stop messages from network access servers (NASs) to members of a remote RADIUS server group configured in NPS.
When you have remote RADIUS server groups configured and, in NPS Connection Request Policies, you clear the Forward accounting requests to this remote RADIUS server group check box, these groups are still sent NAS start and stop notification messages.
This creates unnecessary network traffic. To eliminate this traffic, disable NAS notification forwarding for individual servers in each remote RADIUS server group.
To complete this procedure, you must be a member of the Administrators group.
Click Start, click Administrative Tools, and then click Network Policy Server. The NPS console opens.
In the NPS console, double-click RADIUS Clients and Servers, click Remote RADIUS Server Groups, and then double-click the remote RADIUS server group that you want to configure. The remote RADIUS server group Properties dialog box opens.
Double-click the group member that you want to configure, and then click the Authentication/Accounting tab.
In Accounting, clear the Forward network access server start and stop notifications to this server check box, and then click OK.
Repeat steps 3 and 4 for all group members that you want to configure.
