HI 

I suspect a problem since changes have been made on our IP plan,
I know that both eth1: cards MUST be on same network, but not the same as
eth0:

Can you confirm that ?

If yes, is this configuration good, or not ?

                            eth0:0    

  LAN  <-- -----eth0: SVR1  : eth1: -------cross cable -------- eth1: SVR2 :
eth0 -----------> LAN

And last but not least, what about gateway configuration ?

I suspect problem beacause nmblookup answer 3 ip for my domain master, it
have to be one IP 
nmblookup -U 10.64.1.23 -R "DEP64#1b"
querying DEP64 on 10.64.1.23
10.64.1.21 DEP64<1b>
10.64.1.23 DEP64<1b>
10.64.100.120 DEP64<1b


Thanks a lot for your response
