To export the RMS private key from a software-based CSP
Log on to the RMS server that has the RMS private key installed.
Click Start, and then click Command Prompt.
Type cd %windir%\Microsoft.NET\Framework\v2.0.50727, and then press ENTER.
Type aspnet_regiis.exe –px “keycontainername” privatekey.xml –pri, where
keycontainername is the key container name that you retrieved from the procedure named “To retrieve the private key container name.”
Copy privatekey.xml to the server that will be joined to the RMS cluster.

1. Log on to the server hosting the AD RMS configuration database with a user account that 
is a member of the System Administrators database role. 
2. Click Start, point to All Programs, point to Microsoft SQL Server, and then click SQL 
Server Management Studio. 
3. When the Connect to Server windows appears, ensure that the server hosting the 
AD RMS configuration database is in the Server name box, and then click Connect. 
4. Expand Databases. 
5. Expand the AD RMS configuration database, and then expand Tables. 
6. Right-click the DRMS_LicensorPrivateKey table, and then click Open Table. 
The key container name is stored in the column named KeyContainerName.
