SYMPTOMS
If multiple computers are configured as both RAS clients and RAS IPX servers on the same network, only one of them at a time can dial into a second network using IPX.



CAUSE
When a RAS client connected to Network A and configured as a RAS IPX server, dials through IPX into a RAS server on Network B, the server assigns the client a Network B number. The client (configured as an IPX router because it's a RAS IPX server) advertises the Network B number on Network A. Other RAS IPX servers pick up the Network B number in their routing tables, and when they try to dial into Network B with IPX, they receive the RASPHONE.EXE message:

  IPX CP reported error 744: Cannot use the IPX network number assigned by remote server. Check the eventlog.

The eventlog shows RemoteAccess Error # 20078:

The IPX network number XXXXXXXX configured for the WAN interface is already in use on the LAN. Possible solutions: 1) Disconnect this computer from the LAN and wait 3 minutes before dialing again; 2) Configure this computer for dialout only."



WORKAROUND
Make the other IPX clients dialout-only,

-or-

Configure the RAS server to assign different network numbers to IPX clients. Here is the procedure:

(Control Panel->Network->Configure RAS->Network-> Server Settings: IPX->Configure..-> un-check the checkbox: "Assign same network number to all IPX clients.
