We've had Reporting Services running SQL 2005 on Server 2003 for over a year with no real
trouble. Over the last few months, more and more frequently we'll get this error when
requesting a report through our application. The application is written in c# and is using
report viewer:
the underlying connection was closed:
a connection that was expected to be kept alive was closed by the server.
unable to read data from the transport connection:
an existing connection was forcibly closed by the remote host.
The reports run consistently successfully if we use terminal services to connect to
the server and run them there.
Reporting services and SQL are on the same server.
I've made all of the IIS and RS config changes that I can think of with no success at all.
Does anyone have any thoughts about what might be happening here?
All server and client systems have current updates installed.

Report requests randomly return an "the underlying connection was closed" message
