Get out your TCPIP manual and see what the FTPSERV userid is doing. You
can trace its commands, see results, etc...

It can be stopped and started using an OBEYFILE command.

Thanks for the responses.

>Are all ports really open?  

I think so. I trust the network guy, and he showed me the firewall
settings (which didn't mean a lot to me).

>Can you open a connection going the other way?  

I can do a trace route which appears to work. Access to 10.200.70.35 is
difficult. See below.

Possibly. I don't know how to tell.

>Is the windows machine connecting to z/VM using command line or a GUI?

GUI. 

>Try the dos prompt command line ftp and see if it still fails.

I tried when I visited in December. No luck. One difficulty is that
10.200.70.35 is located at another facility in a high security area with
very restricted access, and visitors are subject to being booted out
immediately if 'something' happens. This includes my contact at the
other facility. That's why I want to try and work the problem from the
z/VM end.

The workstation 10.200.70.35 can successfully FTP out, and the server
10.199.8.15 accepts FTP connections to it, so I don't think that the
Windows firewall is the problem.
