Had it working with changes to NETTSR.  CT-DOS uses a different port than 
CT-Win.  Think I remember confirming the port numbers with network sniffer 
last year.
Dug back through the archived ct-user file and found the following from K1TTT:

Ok, it does seem to work. There are two things to watch out for.
First in starting ctwin the shortcut must look like this if you install
in the default location:
"G:\Program Files\K1EA Software\CtWin\ctwin.exe" -enet
note that -enet comes outside the quotes. This is a windows thing
because the path has spaces in it.
In starting nettsr use a command line like:
Nettsr 100 3030
The parameters are: = the ip address for the dos machine, this must be
different for each machine on the network of course.
100 = default sw interrupt to emulate comtsr4 = broadcast mask. Will actually be ignored in this setup
3030 = port used by ctwin with -enet for networking = broadcast address used by ctwin for networking

I believe CT DOS uses port 9870.  You can change the CT DOS port but not 
the CTWin port.
However if 3030 doesn't work try 5050 .... I thought I used port 5050 to 
make WinTelnetX talk to CTWin last year at CQ WW SSB ....

And, yes .... they should all be the same version.  And back under 9.87 or 
so CTWin would work just fine with Windows 95B .... with an update .... 
haven't tried any of the 9.90 versions with 95.


I used Partition Magic on my XP Pro laptop to make a 700 MB FAT partition 
for CT-DOS, NA and a couple of old programs that don't want to ever run out 
of Windows.  Then I boot from a CD (or a floppy), it goes right into DOS 
and to what it thinks is the C: drive (FAT partition).
