Ok, here is the situation. I have a plethora of these errors in my security
log. These are my school lab computers. They are on a different windows
2000 domain separate from the win2k3 Domain in the building. I have a file
server on my win2k3 domain that these computers connect to via a logon script
that maps a drive to the file server via some win2k3 domain account
credentials. The mapping occurs just fine, and i actually see the successful
login of that account throughout the logs.

However, and at writing time, I am not sure how far the errors below go
back. I am trying to figure out why the errors below are popping up. Why
would these computers be trying to talk to the filesserver using the NtLmSsp
process

I am not sure where to begin the troubleshooting process

Just what is it that you are asking?

The event log you show seems to simply record a failure
of that machine to log in with its machinename$ account,
which of course would not exist in the target W2k domain
unless you did mean to say that these "separate" domains
are either in the same forest of have trust(s) between them.
If they are in the same forest, then it is worth asking why
NTLM is being used, otherwise it is the remaining alternative
as W2k does not support Kerberos over an external trust.
