Migrate RADIUS config from Windows 2003 IAS to Windows 2008 R2 NPS

            

HI,

                 

             Recently we were into Migrating the windows Server 2003 based Radius - Internet Authentication Service (IAS) to Windows Server 2008 R2 based Network Policy Server (NPS) task, so I thought to provide the step we were followed.

To perform this migration, perform the following Easy steps:

Step 1:-

Copy IASmigreader.exe from the Windows Server 2008 R2 installation media at \sources\dlmanifests\microsoft-windows-iasserver-migplugin folder to the Windows 2003 server and run as shown below to export the IAS configurations. It will create the configuration file:

  

Step 2:-

Open the IAS.txt file and find the following text:

=================================================

SystemInfo

=================================================

0

16

515

Replace the text with:

=================================================

SystemInfo

=================================================

0000000009

16

515

Save and import the changed file. This is referenced in http://support.microsoft.com/kb/979599

Step 3:-

Copy the ias.txt file that is generated in the above command and updated as mentioned above to the Windows Server 2008 R2 and import the configuration like so:

At the 2008 R2 Server:

Open NPS console and verify the configurations have been successfully imported.

And now you should register NPS service in Active Directory from the NPS console.

Step 4:-

To register the NPS server in the default domain by using the NPS console:

Log on to the NPS server by using an account that has administrative credentials for the domain.

Open the NPS console.

Right-click NPS (Local) , and then click Register server in Active Directory . When the Register Network

Policy Server in Active Directory dialog box appears, click OK
