Error 18456

I am repeatedly receiving the following error:
Login failed for user 'NT AUTHORITY\ANONYMOUS LOGON'.
This has been occuring since a network wide password
change ( for an employee leaving the company ) and I do
realize that there is some process trying to connect, but
I do not know how to find out what the process is, or
what it is trying to connect as. Is there a way to trace
this information?You may be able to catch this with SQL Profiler and/or a network trace.
The network trace will only work if the connection is coming from a remote
machine.
Thanks,

to track. Haven't tried a network trace, I will try, but
I don't think it is a remote connection. Thanks for your
help.
