[Samba] Samba PDC reliability?

[Beau Sapach]

Hello all,

I'm using Samba 2.2.5 compiled on Solaris 8 for my PDC, I've included my 
smb.conf below.  My client machines are all winnt4.0 service pack 6, but I 
can't get them to log in to the PDC reliably.  Very rarely will they log in 
properly, I usually get the "Domain controller could not be contacted" error 
message.  Does anyone have any advice?  Thanks!

Beau
