Hello

Does these error only come from the one machine that is named server?
Are there any secure channel type of errors on that machine? If so
resetting the machine account may eliminate these errors.

Is this an NT4 machine in a Win2K domain?

sorry...it is a W2K server

Thanks for the article...I had already read through that.
I have also learned that ntlmssp.exe is used with exchange
and some proxy services.

Yes "server" is a domain controller and the machine the
log event is referring to.

I interpret the log as the domain controller "server"
machine account can't log into the network because of a
bad password.

This doesn't make sense to me.

All of the services are running smoothly, from email to
the firewall to backups.

Any other ideas would be helpful.
