P2P error

[asakura797]

Basically at work we are connecting 4 computers on a basic P2P network for testing. It's all working fine, two computers can see the other computers on the network and they can access each other's network drive's no problem. However they can't access the other two hard drives without it requesting credentials. Is there anyway in which anyone knows how to turn this function off? Or shed some light as to why the two computers can access one another's HDD without credentials but not the other computers. (The situation is the same for the other 2 computers, they too access one another's HDD no prob but won't access the other two computers without credentials.)

Thanks in advance guys!

set up equivalent accounts with the same passwords on all pcs and it should work if you add the user rights to the shared folders
