hello
I've been reading the thread
(http://marc.theaimsgroup.com/?t=113286376900001&r=1&w=2) and I have
the same limitation with WINS in a PDC/BDC.
That's why I have the following (experimental) setup:
PDC ==> wins support = yes, passdb backend: master ldap
BDC ==> wins support = yes, passdb backend: slave ldap
I configured some of my XP clients to use both WINS servers and it
seems to work.
but in the manual of smb.conf I read:
wins support (G)
Note that you should NEVER set this to yes on
more than one machine in your network.
What could happen if you use more than one WINS server on your network?
thanks

I will setup a few XP clients with two WINS servers configured and see what happens. but I need this kind of backup because else I can't see the point of setting up a BDC if the WINS server remains the single point of failure. I'm looking forward to Samba4 where "WINS replication support is nearly finished" as I've read on the website (http://us4.samba.org/samba/ftp/slides/tridge_sambaxp05.pdf) kind regards werner Disclaimer: http://www.kuleuven.be/cwis/email_disclaimer.htm

you misunderstood my recommendation: the BDCs should not be WINS server. if you have multiple subnets, each subnet should get its own BDCs for logins to avoid login problems if the PDC and WINS server is down! greez werner maes wrote:> At 10:32 19/12/2005, you wrote: > >> werner maes wrote: >> >>> no, because all our client are not located on the same subnet! >> >> ok, you?re right. that?s another story. >> >> i thought all clients/servers are in the same subnet, because your BDC >> is on the same subnet as the PDC. >> >> why don?t you setup BDCs for each subnet that your clients are at >> least able to login? >> >> greetz > > > problem remains that the single point of failure is your WINS server > (the PDC in my case). it's not recommend that you set each BDC to act as > a WINS server. > > werner > > > Disclaimer: http://www.kuleuven.be/cwis/email_disclaimer.htm > >-- Michael Gasch Max Planck Institute for Evolutionary Anthropology Department of Human Evolution (IT) Deutscher Platz 6 D-04103 Leipzig Germany Phone: 49 (0)341 - 3550 137
