[K12OSN] samba 3.0.23a - cannot join domain

[mrok12osn at eastgranby.k12.ct.us]

I just did a yum update this morning and it installed samba
3.0.23a-1.fc5.1.  Now, I can no longer join new XP Pro PC's to the domain.
 After bringing down the server and bringing up it's backup which still
had 3.0.22-1.fc5, I had no problems adding a lab full of PC's.  I am still
using smbpasswd support for this server and this is the PDC.  I migrated
the passwd, shadow and smbpasswd files from the backup server to the
primary server and now am able to use the new PC's.

I just reported this to the samba list.

So how do I find the install package for samba 3.0.22-1.fc5 and reinstall
it on our primary server using yum?
