SYMPTOMS
========

When you use NWLink and dial in from a Windows NT Remote Access Service (RAS)
client to a Windows NT RAS server, the following system event may appear in the
Event Viewer:

  Event ID: 20087
  Source: RemoteAccess
  Type: Error
  Description: The IPX network number for the LAN adapter with the MAC
  address <MAC address> on the local machine has not been configured
  or could not be auto-detected. The IPX Router will not work on this LAN
  segment.

CAUSE
=====

This problem occurs when the network segment that the Windows NT RAS server is
on does not have an IPX network number.

RESOLUTION
==========

To correct this problem:

- Run Registry Editor to change NetworkNumber from 0 to a valid network
  number.

  -or-

- Install a NetWare server on the network segment that contains the RAS server,
  configure it with a unique network number, and then shutdown and restart the
  Windows NT RAS server.

To change NetworkNumber from 0 to a valid network number:

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.

1. Run Registry Editor (REGEDT32.EXE) on the RAS server.

2. From the HKEY_LOCAL_MACHINE subtree, go to the following subkey:

     \SYSTEM\CurrentControlSet\Services\NwLnkIpx
       \NetConfig\<Network or RAS adapter>

3. Highlight NetworkNumber.

4. From the Edit menu, choose Multi String.

5. Change the value from 0 to a valid network number.

6. Choose OK and quit the Registry Editor.

7. Shutdown and restart Windows NT.
