In my SharePoint 2010 installation when I go to
Central Administration -> Security -> Configure information rights management, select
Use the default RMS server specified in Active Directory and click OK I get the following error:
The required Windows Rights Management client is present but the server refused access. If you are switching from one RMS server to a different RMS server, be sure you have set up a trust relationship between the two. IRM will not work until the server grants permission.
I've set up the AD RMS role on my machine running Windows Server 2008 R2, and near as I can tell everything should be working properly. What's the problem here?
Edit: Wait, will AD RMS work if it's installed on the same machine as SharePoint?
