When you are using a multihomed Microsoft Windows NT Server 4.0-based computer as a router between subnets on a local area network (LAN) that is divided into multiple physical subnets, routing by using the NWLink Internetwork Packet Exchange/Sequenced Packet Exchange (IPX/SPX) compatible protocol on your network may not succeed.
However, Transmission Control Protocol/Internet Protocol (TCP/IP) routing works correctly.
This behavior can occur when each physical subnet does not have a unique external network number.
To resolve this issue, assign a unique external network number to each network adapter on the multihomed Windows NT Server 4.0 router. (The NWLink protocol uses these external network numbers to identify unique network segments.) On each computer in the subnet, configure NWLink to use the correct external number for its subnet.
