samba - Sep 2005 - problems logging in as guest from a windows2k system

Hi,
 
    I had been using samba 3.0.14 and the DC is a Windows2K3 server. I
have setup guest printing.(please see the smb.conf) and am able to view
the printer shares from another Windows2k3 server in another domain.
However, I am not able to access the same shares from Windows 2000
server in another domain. Please let me know if I am doing anything
wrong.

[print$]
path = /state/samba/printers
guest ok = yes
browseable = yes
read only = yes
write list = @printeradmin
force user = root
force group = root
 

[printers]
comment = All Printers
path = /local/local1/spool/samba
browseable = no
guest ok = yes
writable = no
printable = yes

I think it is because of this error. Not sure. Also, Should I be setting
any other parameter in smb.conf to make it work.
