It stops CVSNT doing reverse DNS to verify clients... it doesn't stop
other parts of the system doing so (eg. kerberos will do this as part
of its handshake).  I'm not aware of any way of completely removing

You'll probably find on the affected machine that switching to pserver
will fix the problem, as all the authentication is then internal to
CVS rather than relying on the system configuration.

>2) If it does, what else could be going wrong?

There can be many things that break on a system... CVSNT just
piggybacks on the existing system so assumes that's working.  If the
clock is wrong on the machine for example active directory
authentication will stop working.  If you have the machine name the
same as another machine it'll behave erratically and may break
completely... about a dozen other things I've come across over the

It may just be a straight hardware problem - have you tried a
