This is actually now running on a Windows 2003 server. 
It still exhibits the same behavior.

I've seen it happen on the command line, but it is pretty
difficult to reproduce it that way.  I just tried it 
about 50 times by hand and couldn't get it to happen.

It seems to happen more often with my automated build.  It
is more pronounced when I'm building my automated build 
tool itself.  There are automated tests of the CVS part of 
the application that hit the server pretty hard.  This is 
all done from by exec'ing the CVSNT cvs command from Java.
Note, however, that it doesn't try to do any CVS operations 
concurrently.  I figured that would be asking for trouble.
I'd guess the "ls" problem happens once every 30 runs.

Even during the automated tests, it still only does "cvs ls"
maybe once or twice, so I'm guessing that it might be the
fact that it is doing other operations in rapid succession
before and after this.

I'd tried writing my tool using a couple of the Java CVS
libraries but they failed miserably when subjected to
automated tests.  CVSNT seems to be much more reliable
as a client.
