e found after doing a DB trace that this was actually the
second error message we were getting from the database. The
first, non-fatal one was "TCP Provider: The specified
network name is no longer available." For us, we think what
was happening was there was a network glitch losing a packet
or two between the SQL server and the client and it wasn't
then able to recover and MS SQL Server would time the
connection out.
We still haven't got to the bottom of where the glitch is
happening.
One thing we investigated which appears to solve the problem
for a number of people (but not for us) was the TCP Chimney
settings on the server hosting the database. Googling for
SQL Server TCP Chimney should throw up a few references from
the MS tech support guys.
Hope this helps. Good luck!
