Net-Library errors every 48 hours

At 2:00 AM every other morning we are getting errors that are causing us to
have to restart SQL Server 2000.
The event log registers the following:
Source: MSSQLSERVER
Event ID: 17052
Error: 17825, Severity: 18, State: 4
Could not close Net-Library ''.
We will also see the following error:
Source: MSSQLSERVER
Event ID: 17052
Error: 17059, Severity: 18, State: 0
Operating system error 10093: Either the application has not called
WSAStartup, or WSAStartup failed..
We would appreciate some help as we would like to sleep through the night
again.What application runs against the server at 2:00 am? Why do
you have to restart SQL Server? I'd create a server trace
to run and schedule it to capture the activity during that
time.

You have some issue with a program or app that is doing some
winsock calls. I'd still run some traces. One problem with
rescheduling and changing tasks is that you are only
changing the ones you know about. There can be others you
don't know about.
