2003 SP1 Can not Connect after 24 hours

[Guest]

After upgrading from 2003 to 2003 SP1 my VPN server will allow connections
for about 24 hours then stop. Anyone who is currently connected does not
loose connections but no one else can connect. Stoping and restarting the
VPN service fixes the problem for another 24 hours. This was not an issue
prior to SP1 install.

Any assistance would be greatly appreciated.

Robert thanks for this. I did see this sugestion before and by the advice of
that post changed the MTU value to 1272 (the highest value that woudn't
fragment) and still had the problem. I will see if I drop this down to 1000
(as this one suggested) or lower will help.

Will keep you posted either way.
