IPX/SPX could not be initialized for Winmenu!!! 
Below are some common reasons and suggestions:

1) Check your SYSTEM/INI and be sure you are loading
VIPX.386 driver.  

2) Check you are loading IPXODI at boot time.

3) Check 'Installing Winmenu' in the online documentation 
(admin.hlp) and verify you have the latest Novell drivers. 

4) IPX tried to increase the amount of local memory and couldn't.
 Increase the available memory in your workstation.

5) IPX sockets are in direct conflict with some other application.
Try changing the Winmenu sockets value. These are like 
communication channels which might be conflicting with 
another application using the same sockets. See 'Changing sockets' 
in the online documentation (admin.hlp). NOTE: See C:\NETCOM.log

6) When everything else fails, you may permanently disable the IPX 
functionality in Winmenu.  The IPX function is a trivial one for the
system and not necessary for the intended purpose of Winmenu.  Rename
or erase the file NETCOM.DLL in your Winmenu's directory.
