[Samba] Samba as a PDC

[C & K Rutland]

HELP.  I am running samba 2.2.7 on mandrake 9.0.  I have setup samba and configured my smb.conf file correctly as fair as i can tell but am still having trouble.  When i run testparm everything appears fine.  I can ping every machine on my network but can't get any of my four machines to logon to the domain.  I have three machines with 98 and one with xp.  I have downloaded the xp registry patch yet on every machine it still says it can't find the domain.  I have tried using swat and everything else i can think of.  Can any body offer any suggestions???

Thanks Josh
