remote execution on XP Home SP2

i need something that can be called from script i.e.:
thisprogram \\pconlan -user -pass -ex "ipconfig /renew"
so... there is psexec but it just can't work with Home...
maybe there is some solution with client/server thing, i can
use at last tight vnc but i have 100 comps an must manually
logon one by one to do any simple task....
