So I've installed WfW 3.1, and tried both TCP/IP packages:

Microsoft TCP/IP-32 for Windows for Workgroups 3.11
- no way to install, of course

Microsoft TCP/IP for Windows for Workgroups 3.11
- does install, but...
- no way to configure it, selecting "Settings..." brings "There are no advanced settings required for the selected protocol or network adapter."
- when booting DOS, errors when loading TCPTSR, TINYRFC, NMTSR
- when starting Windows, "Networking functionality will not be available because network protocols were not loaded..."

You'll probably have to borrow some dlls/sys/com files from 3.11
Look at the inf files.
Look at the files in common that are mentioned, but not part of the package.
Try replacing.

Random googling found references to Ms net client 3.

I don't doubt that it can be manually made to work.
I don't think there's much difference between the TCP/IP from DOS client, and the real mode one for WfW 3.11 - and we already know that the former can be transplanted into WfW 3.1.

But the point is:
It won't install work when installed using the normal procedure, so it can't be the same product as the one we're searching for.

It's unfortunate that the version number of the stack is 3.11, because I don't think it's only for WfW 3.11 (but I suspect it might work on that too), and it's probably going to cause confusion 😁

Did you install by running the included SETUP.EXE? It brings up what looks like the normal "Network Adapters" dialog box you can access from the Control Panel, so it might seem unnecessary, but I remember reading some knowledge base article for one of these stacks - quite possibly this one - which said you need to use SETUP.EXE to add the protocol so it can update the Control Panel itself.

I used SETUP.EXE and it seems to work for me:
- PING works from DOS (before starting Windows) and from a DOS prompt in Windows
- I can get Windows NT 4 to connect to a share on the WfW machine over NetBIOS over TCP/IP

I've had a lot of trouble with Windows hanging when I go to Control Panel -> Network though. It seems to happen if I try to do that right after starting Windows, but if I run File Manager and then exit right away it doesn't happen. I tried waiting for longer than it takes me to start and close File Manager but that didn't help. This is quite repeatable!

SETUP.EXE

I thought we were talking about this - https://ftp.zx.net.nz/pub/archive/ftp.microso … /WFW/WFWTCP.EXE - but there's no SETUP.EXE inside that SFX.

Where exactly is the version with SETUP.EXE ?

YES!
@doshea - you have found The Holy Grail!

During WfW 3.1 installation, I added TCP/IP as "Unlisted or Updated Protocol", and removed NetBEUI - but it wouldn't let me enter "Settings..." at this point.
After reboot, I ran SETUP.EXE - and then entered address/mask/gateway - there's no BOOTP nor DHCP, only static configuration!

Unfortunately, it crashes often - doesn't like my 3C509B card? Or my modern Linux/Samba server?
It would be a good idea to try with some other NIC, and/or period-correct server software - like another WfW 3.1 machine, or NT 3.x.

Edit:
Is there some problem with image attachments?
I've set is as INLINE, but can't see it in this post...

The chronology of WfW and TCP/IP, based on files time-stamps:

October 1992 - WfW 3.1
June 1993 - "TCP/IP for Windows for Workgroups" - version=3.11.001
November 1993 - WfW 3.11
January 1994 - "TCP/IP for Windows for Workgroups for WFW 3.11" - version=3.11.060
March 1994 - "Microsoft TCP/IP-32 for Windows for Workgroups 3.11 (March Beta)" - version=3.11.011
August 1994 - "Microsoft TCP/IP-32 for Windows for Workgroups 3.11" - version=3.11.131
November 1994 - "Microsoft TCP/IP-32 for Windows for Workgroups 3.11" (3.11a) - version=3.11.131
May 1995 - "Microsoft TCP/IP-32 for Windows for Workgroups 3.11" (3.11b) - version=3.11.158

I didn't look at that yet, but I certainly saw references in TechNet to using the TCP stacks from both LAN Manager 2.x (client) and MS Client 3 with Windows for Workgroups.

I think there was also an article comparing some of the different stacks. https://virtuallyfun.com/2024/03/18/so-i-used … the-same-thing/ says:

However, despite LAN Manager 2.2 providing a TCP/IP stack to connect to both OS/2 and NT servers, there is no winsock interoperability dll.

I think I saw that in TechNet too - some of these stacks provide alternate socket libraries that aren't winsock compatible. The "holy grail" one I found does support winsock. I assume it might be the only Microsoft stack for WfW 3.11 where you get to adjust settings from within Windows too?

I suppose that might be due to not having run SETUP.EXE yet.

I'll try some testing in emulation soon, against a Windows NT 4 VM. I was using an emulated NE2000. I feel like I should do some testing with winsock too. Perhaps WS_FTP?

I don't know, but yes, I had to click on it.

Thanks also for the summary of all the versions! I recall now that some knowledge base article might have mentioned which stacks have DHCP, etc. Seems like a big table of features is needed!

I assume we are talking about this?

Notice the version number - 3.1 not 3.11

Exactly - "version=3.11.001" in OEMSETUP.INF

If you can get winsock to function on an [emulated] 286, that would really be something. Otherwise I don't see what additional functionality this would offer over my method of grafting in the net client 3 files other than ease of setup. All the files on this disk are essentially just older versions of the same stuff.
