SYMPTOMS

NWLNKIPX sends the broadcast Routing Information Protocol over IPX (RIPX) packet over the network, even if a frame type and network number is selected manually.


RESOLUTION

To resolve this problem, obtain the latest service pack for Windows NT 4.0 or Windows NT Server 4.0, Terminal Server Edition. For additional information, please see the following article in the Microsoft Knowledge Base:

After applying this fix, use the steps below to create a new registry value.

WARNING: Using Registry Editor incorrectly can cause serious problems that may require you to reinstall Windows. Microsoft cannot guarantee that problems resulting from the incorrect use of Registry Editor can be solved. Use Registry Editor at your own risk.

For information about how to edit the registry, view the "Changing Keys And Values" online Help topic in Registry Editor (Regedit.exe) or the "Add and Delete Information in the Registry" and "Edit Registry Data" online Help topics in Regedt32.exe. Note that you should back up the registry before you edit it.

  1. Run Registry Editor (Regedt32.exe).


  2. Go to the following key in the registry:

    HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services
    \NwlnkIpx\Parameters

    NOTE: The above registry key is one path; it has been wrapped for readability.


  3. On the Edit menu, click Add Value and use the following entry:

    Value Name: NoBcastRipRequest
    Data Type: REG_Dword
    Value: 0 or 1
    Default: 0

    Description: This parameter determines if NWLNKIPX sends the Broadcast RIPX packet during initialization. Set this value to 1, if you do not want to send a Broadcast RIPX packet during initialization.


  4. Close Registry Editor.


  5. Restart the computer for the registry change to take effect.



STATUS

Microsoft has confirmed this to be a problem in Windows NT 4.0 and Windows NT Server 4.0, Terminal Server Edition. This problem was first corrected in Windows NT 4.0 Service Pack 4.0 and Windows NT Server 4.0, Terminal Server Edition Service Pack 4.


MORE INFORMATION

When NWLNKIPX starts, Routing Information Protocol over IPX (RIPX) broadcasts are sent to determine the frame type and network number. This RIPX packet is needed only if the auto-detect feature of NWLNKIPX is selected.
