Re: TCP connections suddenly failing.

The clusteipaddr was fine on both instances on both all servers within
the cluster.

I want a root cause, but we took the cluster group offline and brought
it back online and that resolved the TCP connect issue.

I am running a large mission critical application on a cluster. This
is a 2003 server latest SP with SQL 2000 Enterprise latest SP also.

This app has run for years with little change. Today at around 3:00
all connections stopped coming in.

After some debugging, we found that we could connect with named
pipes., but not TCP. TCP has been the default protocol for years.

We have the server monitored and no changes occurred recently. The
server has not been rebooted in months, and the last time the instance
was restarted was two months ago.

What can cause a server that has run reliably using TCP for years to
stop accepting TCP connectionsl suddenly?

The errors I am getting is a handshake error trying to connect locally
using TCP, and I get a connection failed error remotely.

Connections are instant and lovely using named pipes.

Thanks for any help.- Hide quoted text -
