Peer 2 Peer network (3 machines) 1 new machine with W7 Pro running in XP VM environment (machine A) 2 machines XP (machines B & C) Testing only A and C at moment - will apply settings to B when A and C are working Set up an administrator user account with password on A for the C machine C sees A and a login screen for A Login fails due to A not accessible or permissions error. Turned off user account protection A and no change. Any ideas greatly appreciated. Wish I had bought downgraded OS to XP, would have been simpler, but wasn't aware of that option at the time of purchase. So here I am.
