I have a Windows NT 4.0 SP6a RAS Server that RAS and VPN clients can connect to but are unable to use TCP/IP services. The odd thing is, this worked up until a few weeks ago. The clients are receiving their IP,WINS and default gateway addresses froma DHCP server. The WINS server IP gets assigned and you can browse the network resources. As for IP, the default gateway on the client gets assigned the same address as the client itself. I can ping the loopback and the client IP but nothing else. Ihave double checked my DHCP server settings and reapplied service pack 6a and now am completely baffled. Any ideas?
