(Extract from README included with ftp://ftp.cdrom.com/16bit/network/
ndis/ndis.zip. This is probably some kind of update of an old PC/TCP
for OS/2. This is where I got the NETBIND.EXE from.)

10-17-89:
As Microsoft released netbind.exe into the public domain, it has been 
decided to distribute this as a service to users.  Using this, one may 
use any of the NDIS drivers with whatever protocol stacks they desire, through
the facilities of the Protocol Manager.  Pending the release of new 
documentation, I hope this readme file suffices to show you how to get it 
working.  First step is to create a config.sys to load the drivers:

[...]
Make sure that the two files, pro.msg and proh.msg are in the
same directory as netbind.  These are required.  If netbind succeeds, run
the Generic Ethernet kernel, ethdrv.exe.  At this point, the PC/TCP Software
is ready for use.  

Note that FTP Software Inc. supports the modules dispktpm.dos and ethdrv.exe,
as well as all of the PC/TCP Application programs.  The protocol manager and
netbind.exe and the NDIS drivers are not supported by FTP Software.
