[dba-SQLServer] Reporting Servers error (SQL 2005)

Arthur, I used Express yesterday for the first time in a few months and I
had a similar problem -- couldn't connect, but it had nothing to do with
Reporting Services. It took me a while to find the problem, but it was as
simple as enabling a protocol that had been disabled (don't know how or when
that happened). Even though the service was running, it still wouldn't
connect and enabling the protocol did the trick. I don't think my exact
solution will help you, just suggesting that it might be a simple property
that's not enabled. I'm not familiar enough with Reporting Services to even
suggest what.
