[mpich-discuss] Getting started in Win XP

OK, I read the section on Firewalls. Looks like having some ports as
exceptions would be the most convenient, but I don't know what are sensible
numbers for ports or how many ports it would make sense to list as
exceptions.

So, I took the program name route. I'm pretty sure I overdid it, but I did
achieve success. I have copies of mpiexec.exe, smpd.exe and fpi.exe on both
of my PC's (Issac & Gauss). In fact, I happen to have two copies of fpi.exe
on Gauss. My first shot was to list all of these as Firewall exceptions on
the PC they resided on. That didn't work. Since I am running with Issac as
the host, I guessed that the copy of fpi.exe on Issac is getting shipped to
Gauss so I should list fpi.exe with its path on Issac as a Firewall
exception on Gauss. That worked.
