TL;DR
How do I tell, on the server, which documents are protected by AD-RMS
I inherited a small environment where Active Directory Rights Management Services is in use. The server is near end of life, and we don't want to replace it, and no longer need RMS. The issue, is that there are hundreds of documents with RMS protection on them, and I don't know how to check which documents, without opening every single one.
My fear is that the server will die, and I will find out which documents were protected, because no one will be able to open them anymore. Is there a way to quickly/easily determine which files query AD-RMS when they open, from the server?
