Hi Bob,

Reason I think the error is related to connection pooling is cos of
the article on MS support site
http://support.microsoft.com/default.aspx?scid=kb;en-us;328476

The web site I have servers 20,000+ users. Out of 100,000 hits to the
IIS server around 200 or at most 2000 fail with the "server not found"
error message. The above article clearly states that it is related to
Connection Pool (I have already completed the TCP/IP tasks without
success)

If connection pool is setup on the client, it is possible to monitor
the SQL server connections using perfmon - if the connections grow ;
it means that connection pooling is not working. And this is exactly
what is happening in my case. If you have some other way of proving
that connection pooling is fine ; I will gladly accept your point of
view.

Thanks for the reply Bob, appreciate it.

Kevin.
