Hello,
we have a setup with a main samba server an an emergency server which synchronizes its data via rsync. Recently, I got the idea to run the emergency server under a different server name parallel to the main server so that users can easily recover deleted files etc. This lead to massive problems; the reason was that the clients randomly connected to the main or the backup server ! The setup is essentialy this :
Main server : DNS : mainserver.local.domain IP : 192.168.2.1 NETBIOS name : MAINSERVER - master browser - domain master
Backup Server : DNS : backupserver.local.domain IP : 192.168.2.2 NETBIOS name : BACKUPSERVER - no master browser - no domain master
What happened is that I run the backup server as main server for one evening while repairing the latter. I ran it under the ip and NETBIOS anme of the name server. Then I switched back. The following day, clients would randomly connect to the backup or main server like mad, causing a lot of confusion. I was under the impression that the windows clients follow the results of the WINS resolution for their connection requests. But now I suspect they cache the MAC address an use this for connecting. It cant't be the ARP cacghe itself because other services (e.g. mail) have no problems connecting to the right server; it must be specific to the Windows networking protocols.
Any idea what is happening or how this could be avoied ??
Yours, Jakob Curdes
