SYMPTOMS
An ACC Nile router (with no filtering) is running IPX over a token-ring network (a non-NetWare network). Both a Systems Management Server and a Windows for Workgroups computer are using the IPX/SPX compatible transport protocol (NWLink) to communicate. However, if a Windows for Workgroups computer is not on the same ring as the Systems Management Server, remote control does not work. The Windows for Workgroups computer can properly connect to computers on the same, far side of the router, but cannot connect to computers across the router.

NOTE: Although this article mentions an ACC Nile router running IPX over token ring, this symptom also applies to other routers.



CAUSE
This problem occurs because the Windows for Workgroups computer is not responding to the NBIPX Find Name requests sent by the Systems Management Server across the router. The Systems Management Server is not able to remote control or connect to the Windows for Workgroups computer.



RESOLUTION
To correct this problem, use an ACC Nile router command that changes the IPX network functional address to FFFFFFFFFFFF from the default token-ring address of C00000800000. The default address that the router port uses to send IPX broadcast packets in an ethernet network is FFFFFFFFFFFF.



MORE INFORMATION
On the same side of the router, the Systems Management Server sends a request packet using the MAC destination address of FFFFFFFFFFFF to a Windows for Workgroups computer. However, the Systems Management Server across the router sends the MAC destination address of C00000800000, which the Windows for Workgroups computer on the other side of the router ignores. A Windows 95 computer accepts either one of addresses.
