Ever since I upgraded my machine from FC2 to FC3, I've been having 
network issues.  In the course of debugging problems with my samba 
shares, I discovered that named.conf had been swapped out.  Switching 
the file names back seems to have resolved the samba shares problem.  
I'm not sure that issues related to it operating as a PDC have been 
resolved.

After my FC3 machine is up for 15 to 30 minutes, all the connected Win2k 
resources start failing.  The various PC's no longer can access each 
other's shares, including shared printers.  If a user attempts to log 
into one of the machines, if the user hasn't already logged in on that 
particular machine, she will get a message saying that the domain is not 
available.  If you try to access one of the shares, it will present you 
with an authentication dialog box, but you will fail every time.
    

Sounds like your linux system is fighting with another domain
controller.  If you want samba to win the election to become browser
master you need to set the os level parameter to 32 or higher.  I
believe it defaults to 20. 

  
I've currently got my Linux box set to 60, which was sufficient with FC2.  I've also got it set to be the "preferred master" and "domain master".  My smb.conf is attached.
