Thanks for the reply.
I have also noticed that my remote VPN clients don't have this problem.
Nor
do client that use a RAS dialer to get in--only those remote clients that
don't get a local address assigned to them when they connect have the
problem. Problem is I have lots of non VPN capable clients out there.
