This is a strange one. A few days ago, our users started having
difficulty connecting to SQL services using TCP/IP. Changing their DSN
to named pipes resolved the issue. Users today started having trouble
connecting to our Captaris Rightfax server over TCP/IP, again switching
to named pipes resolved the issue.

The relevance to this list comes in where we contacted Captaris support.
The frontline call answerer was aware of this problem, and said she had
received numerous calls today about this issue. She had been told by
second level support that this was a Microsoft issue, and that they were
investigating the cause. All clients who had called in had resolved the
issue by re-applying Windows 2000 service pack 2.

Anyone have any idea why TCP 1052 would suddenly start being used by
another service or application? We have not introduced any new apps into
production, yet a netstat -a shows that something is listening to port
1052 on the Rightfax server, even after stopping the Rightfax services.

I am preparing to install something akin to Anasil to check out the
traffic on port 1052. Anyone else out there experiencing anything along
these lines, and have any lead on what could be causing this?
