I am trying to implement RMS server with sharepoint in my office environment.

Environment:

Domain A: 1 RMS server
               1 Sharepoint Server

Domain B: No RMS server
               No Sharepoint Server

Trust relation has been established between two domains.

When a document is uploaded based on the rights the user has on the
sharepoint portal document is rights protected. When Domain B user tries to
download an unprotected file the rights protection is falling in place but
when a Domain A person tries to download the file I am getting an error which
I have attached.

The error is showing :  "could not open
'http://sharepoint.a.com/sites/test/Shared Documents/Unprotected.doc'."
