Authentication prompt when UNC into XP Pro machine from Win2K mach

I have two cilent machines in a peer to peer network. One is a Win2K box
(Client1) and another is a XP Pro box(Client2). They are on the same subnet
mask and are able to ping each other. I have both firewalls turned off and
have ensured that file sharing is enabled on both machines. Both admin
accounts are named differently and currently have different passwords
assigned to them.

I can UNC into the Windows 2000 box from the XP Pro box without any
authentication popups and can view any shares to include printers. However,
when I attempt to UNC into the XP Pro box from the Win2K box, i get prompted
for Authentication. On both machines, I set Digitally Sign Server/Client
communications (when possible) to enabled and Digitall Sign Server/Client
communications (Always) to disabled. Also I set Secure Channel: Digitally
encrypt/sign secure channel data (when possible) to enabled and (Always) to
disabled. My NTLM settings are Send LM and NTLM-User NTLMv2 when possible.

My big question is do I have to set up like users with the same passwords on
both systems in order to avoid the authentication? I know this will work,
but am looking to avoid that if at all possible. Also if anyone could tell
me how I am able to UNC into the Win2K box without authentication while I get
hit with it UNCing into XP from Win2K, that would be excellent as well.

Thank You,

Went ahead and configured user accounts on XP that matched Win2K with same
passwords. Everything working great now.
