Will do.  Further research shows that the client was not a domain 
member, though most of our clients haven't been migrated yet and aren't 
having this problem.  It'll take some time to capture the diagnostic 
information since it doesn't happen more than a couple of times/week.  
In order to reduce the number of packets captured, will a trace to ports 
139 and 445 be adequate?

Thanks for your support.
