[Samba] Problems Winbindd/Squid ?

[Phibee Network operation Center]

Hi

i have a big quantity of problems with Winbindd/squid ... it's very 
unstable on my proxy server and don't know why ...

first problems:

1- I have restart my PDC and after restart, my winbindd denied all 
access and put a INVALID_COMPUTER_NAME ...
i restart winbind and that's work now ... winbindd can't contact another 
PDC ? he can't recontact automatiquely the PDC
without a manual restart ?

2- In the log, i have a big quantity of (into logh.nmbd):
[2005/06/06 12:27:18, 2] 
nmbd/nmbd_nameregister.c:wins_registration_timeout(184)
  wins_registration_timeout: WINS server 172.16.1.15 timed out 
registering IP 10.206.1.251

into squid, i have a lot of "TCP DENIED" and one line after a acceptation ..

i don't understand why this is very unstable ....
