-Thanks for the MATLAB tech support plug.
-Gregory consulting was able to solve it.
i.) Uninstall MATLAB
i.ii.) Manually deleting the left over files in [MATLAB]\matlab2010a.
i.iii.) Manually delete any log files if exist relating to the distributive process.
ii.) Fresh install.
NOTE: The reason I performed the above also is because I changed the 'hostname' on Ubuntu head node and for some reason the old name is remembered on slaves and '-clean' didn't help.
NOTE: The mdce service seems finicky. Meaning, make sure all PC's can ping each other through the firewall, even if they can talk to each other but not ping.
Such as the command:
netsh firewall set icmpsetting 8 enable
-If the above does not work for ping. Turn off firewall, try ping, it should work. Turn firewall back on. Ping now works.
-Take away message: if a mdce service starts becoming confused. My solution here is to perform a complete reinstall.
