I have a question regarding creating shares on a peer to peer
network.  I recently encountered a network that was setup with a peer
to peer configuration even though there was a Windows 2003 server on
the network.
The network was setup by someone else and he created unique usernames
and passwords for each node on the network.  My question is, what is
the easiest way to allow shares on a machine without adding every user
on the network to the machine that needs to share?
They don't want to go to a domain setup for some reason.

Thanks in advance!
