Can you first try if this works:

proof.conf:

node localhost

slave localhost
slave localhost


and:

gROOT->Proof("localhost")

This should create 3 proof processes on your local host.

root [0] gROOT->Proof("localhost")
**** Welcome to the PROOF server @ pcsalo.cern.ch ****
**** PROOF slave server @ pcsalo.cern.ch started ****
**** PROOF slave server @ pcsalo.cern.ch started ****
PROOF set to parallel mode (2 slaves)


Cheers, Fons.
