Hello,
Documentation states that one should set up only one Samba server as WINS
server.
While NT's TCP/IP setup has two entrys, one for a primary and one for a
secondary WINS server I wonder why there
should be only one Samba WINS server.
Has anyone tried this with two Samba WINS servers? Did you suffer from any
interferences.
I did and the machines are running perfectly smooth. Did I miss something?
What is the background behind the restriction in the docs?
Regards,
Robert

As Microsoft plan to retire wins in favour of DNS in the very near future, I'd recommend using it cautiously, and making sure you don't depend on anything peculiar to WINS.

In my environment there is no MS WINS server, only Samba WINS servers. From trying I know that MS clients can resolve NETBIOS names by broadcasting a WINS request and Samba will answer to these requests as long as it is configured with "wins proxy = yes". The lookup in my environment depends on /etc/hosts only and this one should be in sync nearly all the time because it is fed by NIS. This is really convenient because now all clients can use anything in /etc/hosts without having to configure something special on them. Is this situation a legal exception from the rule not to setup two Samba WINS servers? Its just for the case that one machine in a net with two or more Samba servers goes down. If this were the machine with the only WINS server on it no more name resolving would be possible ...> As Microsoft plan to retire wins in favour of DNS in the very >near future, I'd recommend using it cautiously, and making sure >you don't depend on anything peculiar to WINS. > > If you do You Will Hate Yourself Later (:-)):-) I already learned that its wise to configure "wins support = no" and to point to a "wins server" when there is one and you have to insert a Samba machine in this net. But in this situation all the clients already know about some MS WINS server and I only have to care that Samba registers with it.
