Program Will Not Run from FPNW Volume

ID: Q199208

The information in this article applies to:
  • Microsoft Windows NT Server versions 3.51, 4.0
  • Microsoft Windows NT Server, Enterprise Edition version 4.0
  • Microsoft File and Print Services for NetWare version 3.51
  • Microsoft Windows versions 95, 98

IMPORTANT: This article contains information about editing the registry. Before you edit the registry, make sure you understand how to restore it if a problem occurs. For information about how to do this, view the "Restoring the Registry" Help topic in Regedit.exe or the "Restoring a Registry Key" Help topic in Regedt32.exe.

SYMPTOMS

Windows 95 clients will not be able to run a file that is on a File and Print Services for NetWare (FPNW) volume if they are using the Client for NetWare Networks. These same files can be run when using the Client for Microsoft Networks. Windows NT Workstation and Windows for Workgroups clients do not have any problems running these programs.


CAUSE

The Client for NetWare Networks under Windows 95 does not negotiate a correct IPX packet size with the server. If the maximum packet size (MaxPktSize) on the server is set to a specific value, and not the default of 0, this error may occur.


RESOLUTION

WARNING: Using Registry Editor incorrectly can cause serious problems that may require you to reinstall your operating system. 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" Help topic in Registry Editor (Regedit.exe) or the "Add and Delete Information in the Registry" and "Edit Registry Data" Help topics in Regedt32.exe. Note that you should back up the registry before you edit it. If you are running Windows NT, you should also update your Emergency Repair Disk (ERD).

NOTE: Registry keys in the following procedure may appear on two or more lines, but are actually one path; they have been wrapped for readability.

If MaxPktSize is set to 240 change it to 0 via the Registry.

  1. Run Registry Editor (Regedt32.exe).
    NOTE: It is recommended that you first save each registry key before deleting it.


  2. The MaxPktSize information is located in the following registry key:

    HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\NWLnkIPX\NetConfig\<adapter_name>


  3. Double-click MaxPktSize and set to 0.
