I don't remember any particular resolution or fix. From a command line
you can run the SETUP.CMD command file that's located in \MPTN\BIN\ --
that's how your CONFIG.SYS gets your machine started.

I've been getting a lot of TCP/IP hangs the past couple of weeks since I
switched to a different POP email host provider. Near as I can figure
my 4.02y stack isn't timing out when a request doesn't receive a
response. The 4.0 stack only allows for 2000 sockets so a lot of
"hanging sockets" will eventually fill the table and cause a freeze.
(Closing the apps or command line windows which these hanging sockets
are assigned to seems to free them.)

To troubleshoot:
===============

First ping yourself:

ping localhost
or
pint 127.0.0.1

to make sure your stack is working. (If your \MPTN\ETC\HOSTS text file
doesn't have a "127.0.0.1 localhost" entry then skip this step.)

Then ping your Domain Name Server to make sure it's available, for
example:

ping 4.2.2.1

(4.2.2.1 is Verizon's DNS - use your own ISP's DNS IP address instead.)

Then use NSLOOKUP on any known-good domain to verify that your Domain
Name Server (DNS) is working and can resolve URLs:

nslookup san.rr.com
-and in reverse-
nslookup 24.25.195.1

Maybe something in the above will help.
