No Communication Occurs between Two Networks
142 Internetwork Packet Exchange
Cause 3 —System is declaring itself the owner of the LAN, even though it is
not the owner.
Reinitialize the system.
Cause 4 —LAN has become partitioned temporarily during normal NLSP
operation. This should occur only during an NLSP system's startup, and the
error should be corrected within a few minutes.
Verify that the condition does not persist. If it does, check for a hardware
problem or for NLSP software incompatibility with other systems.
Connectivity is lost because a router is missing required routes. This
router's table is not consistent with the routing tables of other routers.
The router has not converged because it is configured for multicast and
the driver does not support multicast, even though the driver's
documentation claims that it does. Set the MAC Channel option to
Broadcast (parameter path: Select Bindings > a specific binding > Expert
Bind Options > NLSP Bind Options).
A workstation cannot communicate with a server on a different
connecting LAN, but other systems on the LAN can communicate.
Cause 1 —Physical problem on the workstation (for example, a broken
LAN card).
Replace the malfunctioning hardware.
Cause 2 —Packet filter that is discarding the system's packets has been
implemented somewhere in the network.
Check each intervening router and correct the filter configurations.
A server cannot communicate with another server on a different
connecting LAN, but other systems on the LAN can communicate.
Cause 1 —Server is misconfigured.
Correct the server's configuration and make sure that it has connectivity
by verifying that it has the routes and services typical for your network.
Cause 2 —Connectivity exists, but it is so poor that the transports above
IPX cannot maintain connectivity.
Set up an IPXPING test between the two systems. If the rate of dropped
packets is high, the connectivity problem is probably caused by a
