netbios-ns and wins server

[Jose Rafael Xavier dos Santos]

Hi

	When a I use wbinfo -u --domain=DOMAIN_NAME in my proxy server (squid 
+ winbind), it tries to resolve the PDC netbios name with the Wins
Server. OK!. 

Doubt:  For some domains wbinfo tries to resolve twice, on the WINS
Server and Domain PDC. Is it correct?

My problem was resolved with new firewall rules (udp/137 to domains
PDC's); but my doubt still exists...

PS.: Squid 2.5-5 + Samba 3.0.4 accessing NT PDC's
