Re: [Samba] Changed PDC IP, all hell broke lose
I think you can/should have them remove the PDC from their WINS entry on their end and then you can rejoin the network with the new IP Address. Outside of that, I can only suggest looking into how to send an update to a record on a WINS server from a Samba PDC. I'm unsure if that is possible as I have only run a fully Windows or a Linux/Samba with Windows Clients as a network. -- Regards, Robert Adkins -Original Message- From: samba-boun...@lists.samba.org [mailto:samba-boun...@lists.samba.org] On Behalf Of Paul Raines Sent: Tuesday, September 04, 2012 2:24 PM To: samba@lists.samba.org Subject: Re: [Samba] Changed PDC IP, all hell broke lose It is definitely an issue with the WINS server which returns the old IP address # nmblookup -U 172.27.88.81 -R 'MRIRESEARCH#1b' querying MRIRESEARCH on 172.27.88.81 132.183.202.95 MRIRESEARCH1b SO it is not automatically picking up the IP change which happened 4 days ago and I have restarted samba on my PDC several times.

I have no idea what the WINS server is except that I am sure it running on Windows since they are totally Windows-based organization. So the WINS server is definitely the problem?

Re: [Samba] Changed PDC IP, all hell broke lose
I'm in a similar situation, and have run into your issue once. I work at a hospital, have several freebsd boxes running samba and joined to the Windows-based domain. I am *not* using my samba servers for auth, rather just depending on Active Directory for that. However, there are two things to check when it's acting like you have the wrong IP. 1st one is easy - on the samba box, please check the hosts file, I've made that mistake a couple times - change the IP but not the hosts file. 2nd one is if you login to a windows domain, you need to remove your node out of the directory - or have them do it. See, the box will be registered in A/D and it will have some information associated with it in A/D. I don't know the entirety of it, but removing the machine totally out of A/D has solved a number of problems for me - allowing me to re-join and proceed with the day. Good Luck!

Re: [Samba] Changed PDC IP, all hell broke lose
Okay, someone else will need to answer on how WINS works, but something else might be going on here. On a windows machine, if you do a ping -a, you'll get ping to resolve your name. I'd check both old and new IPs. Granted, the old won't reply, but you'll see the DNS query go through anyway. What that means then is that the IT staff on the other side has manually loaded a DNS entry into Active Directory, and WINS is pulling from that because that's the information is has to work from. Perform some DNS querys against the A/D dns servers, see if they have the old IP or new one or just plain none at all for your server...
