Hi all,
we have got 4 Samba Servers. All BDCs for "MYDOMAIN", except by SERVER3 that is
a PDC.
All of them have 3 physical Network interfaces, from which 2 are used by samba.
Each of them has a several ip aliases, except by SERVER1 which has only primary
ip numbers on its interfaces.
When I try to join a new Windows client (XP SP3) to the domain. It asks our
wins server for MYDOMAIN<1c> and gets a correct reply with all primary ip
numbers of all SERVERs.
The Windows client picks one in its network and does a SAM LOGON request.
Then there are two possibilities:
1) Either it picks a SERVER2-4 with ip aliases on its interfaces. Then the
SERVER responds with a different ip number than the client sent its request to.
So the client does not recognize the SAM Response "user unknown" and does not
pop up the requester for a valid domain admin username and password. After a
while it displays an error message instead. And the join procedure cannot go on.
2) Or it picks SERVER1 whithout ip aliases on its interfaces. The SERVER
responds with the only ip number on its interface in the client's network. So
the client does recognize the SAM Response "user unknown" and pops up the
domain admin logon requester and the join procedure can continue.
?????
So, why does SAMBA not reply on the same ip number ist was queried?
How can I get SAMBA to reply on the same ip number ist was queried?
