Hi,

I have set up  Samba-3.0.11 to retrive account information from W2k 
server via winbind, and it works.
But is takes about 10 sec. to retrive the information.

I have dumped some traffic from the request, and it looks like this:

A lot of these:
21:21:55.133423 172.20.3.131.1077 > 172.20.3.130.137: NBT UDP

And at the end this.

Seem like some sort of name-resolution problem, but i have no idea about 
what is missing.
I also have no clue about the DNS lookup of MAIL comes from, there is 
none and never has been  ?

Anyone a hint ?
