I used your method and I get the error- An internal error occurred on the
report server. See the error log for more details. (rsInternalError) Get
Online Help
The source of the report definition has not been specified.

My .Net command-

Process.Start("http://localhost/ReportServer?/Pages/Report.aspx?ItemPath=%2fLegReviewRS%2fReviewDetail&rs%3aCommand=Render&RevID=" & CurrentRevID)

It is a hidden parameter.

This has always worked with the following parameterized command-
Process.Start("http://localhost/Reports/Pages/Report.aspx?ItemPath=%2fLegReviewRS%2fReviewDetail&rs%3aCommand=Render&RevID=" & CurrentRevID)

The only problem is I get prompted on the reviewer which I would like to
eliminate.
