If you are unable to PING a router on a remote network from a RAS client, using TCP/IP, after you receive an IP address from the RAS server:
1. The most frequent cause is that you installed a network component and failed to reapply your latest service pack.
2. The router's ARP cache contains this IP address with a different MAC address.
To resolve the problem:
1. Apply your lattest Service Pack.
2. Clear the IP address from the router's ARP cache. Check with the manufacturer for how.
