You cannot configure a Windows NT computer through the user interface to access two different IPX networks on two different network adapters, each with a different frame type. If you run Control Panel, choose Network, select each adapter, and assign a network number, the same network number is used for both network adapters. In order to provide the network number for each network card, you must modify the Windows NT Registry.

WARNING: Using Registry Editor incorrectly can cause serious, system-wide problems that may require you to reinstall Windows NT to correct them. Microsoft cannot guarantee that any problems resulting from the use of Registry Editor can be solved. Use this tool at your own risk.

 Start Registry Editor (REGEDT32.EXE). From the HKEY_LOCAL_MACHINE subtree, go to the following subkey:

SYSTEM\CurrentControlSet\Services\NwlnkIpx\NetConfig\

where is the network card you are configuring for a different IPX network. Remove the entry: NetworkNumber From the Edit menu, choose Add Value. Add the following:

Value Name: NetworkNumber

Data Type: REG_MULTI_SZ

Data: 

 If necessary, repeat steps 2 through 4 for each network adapter. Quit the Registry. Shutdown and restart Windows NT.</li></ol>
