The information in this article applies to:

- Microsoft Windows NT Workstation versions 3.5, 3.51 
- Microsoft Windows NT Server versions 3.5, 3.51 
- Microsoft Windows for Workgroups version 3.11 
- Microsoft Windows 95

SYMPTOMS
========

When Remote Access Service (RAS) is installed on a Windows NT Server running
NWLink (IPX/SPX) protocol, client/server applications that depend on SAP and RIP
protocols may not be able to connect to their servers.

Btrieve is one such application. Btrieve clients may appear to hang when they are
unable to access the Btrieve database engine running on the NT server.

CAUSE
=====

When RAS is installed on the NT Server, also installed is an IPX router. This
router considers zero to be an invalid network number. If, under the
configuration option for NWLink, autodetect is chosen for frame type and no
routers or a Novell server is present on the local network, then zero may be
chosen as the network number. If IPX/SPX protocol frame types are configured
manually, then the network numbers associated with these frame types default to
zero.

You can find out (http://support.microsoft.com/download/support/mslfiles/out) the
network numbers associated with a given frame type by executing the IPXROUTE
CONFIG command at a command prompt.


WORKAROUND
==========

To solve this problem, enter a valid network number for each frame type
specified in the registry on the Windows NT Server. (A valid network number is
an eight-digit hexadecimal number whose value is greater than zero; for example,
AABBCCDD.)

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. Open the Registry Editor (Regedt32.exe).

2. Go to the following location:

  HKEY_LOCAL_MACHINE\SYSTEM\CurrentcontrolSet\Services
  \NWLnkIPX\Netconfig\<adapter name>

3. Look for the value entries for the NetworkNumber and PktType parameters.

4. Each value in the PktType parameter specifies a frame type, and and each
  frame type must have a corresponding value entry in the NetworkNumber
  parameter. For details on these settings, see:

  "Services for NetWare Networks: Microsoft Windows NT Server," version 3.5,
  Appendix A, Pages, 114-115.

5. Restart the computer.
