It is doable -- could you post your /etc/samba/smb.conf?  As to whether 
or not it is advisable as a replacement for a Win2k environment there 
are a few things to take into consideration:

1. Samba3 cannot act as an Active Directory DC
2. If you want any failover you will need to have an LDAP backend
3. Fedora Core is not supported -- you might wish to consider moving to 
a supported OS (RHEL, SusE, Solaris etc.)
4. Staff needs to have the appropriate *nix/Samba skills to administer 
the environment
