[mpich-discuss] mpich2 1.0.8 on windows - domain required?

[Thomas Blom]

Yes, I've tried this.  To eliminate questions about the machine name etc...
I have

1.  go through network setup wizards again to establish that the machine
name is mb13 and the workgroup is LOGIC; disable  firewall.
(reboot)

1.5 Verify that I can share a folder on mb13, and from the other computer
can successfully map a drive to \\mb13\sharename -- this establishes that
mb13 is the recognized computer name.  And that other computers can reach it
at that name.

2.  uninstall mpich2 completely
3.  install mpich2
(reboot)

4. mpi -register, and provide username/password of an account on the machine
that is a "computer administrator" (thomas)

I still am unable to simply run mpiexec -n 2 hostname.... I get the same
"Credentials for thomas rejected connecting to mb13"

I am able to run 'smpd -status' and it tells me that smpd is running on
mb13.

Good grief... (my build from source & testing on two bsd-based macs took
about 15 minutes)
