Re: NT Routing ?!?! Help Please !

Enable IP Forwarding in the TCP/IP Properties. (That is if it is not
already done). Just for everyones knowledge - we had a heck of a time
getting two NIC's to work in an NTserver. Come to find out, the Nic
talking to the outside world was required to load up first in the bindings
section. Who would have known......

Anyway IP forwarding is found under the routing tab. That will allow NT to
forward IP to the outside world (theoretically). Hope this helps.
I haven't been keeping up on prior postings to this, so I hope this is not
a repeat :)
