I had to move my RedHat 5 box acting as a PDC to a new IP address. It is
running samba 3.5.10. After the move, none of my windows or linux samba
clients worked anymore. I tried rejoining some to the domain, but would
get error
Unable to find a suitable server
Join to domain 'MRIRESEARCH' is not valid
The old PDC IP address is 132.183.202.95 and nothing is at that IP anymore
(for 4 days now). The new IP is 172.21.21.35
I ran 'net -d 10 join' and would see it was still trying to connect to
the old IP address. I tried 'net cache flush' to no avail. I shut
down samba, removed every file in /var/cache/samba and still no change.
It tries to go to the old IP address.
On the PDC box, I increase 'os level' from 60 to 70, stopped the nmbd and smbd
processes, did a 'net flush cache' and restarted nmbd and smbd. Still it
fails and the nmbd log as the following.

=============================================
Where is it still getting the old IP address?
The the clients are all set with
remote announce = 172.27.88.81
wins server = 172.27.88.81
security = domain
password server = pdc.nmr.mgh.harvard.edu
workgroup = MRIRESEARCH
The WINS server is run by central IT group of the hospital and I have
no control over it.
DNS is properly changed:
# host pdc.nmr.mgh.harvard.edu
pdc.nmr.mgh.harvard.edu is an alias for raidsrv01.nmr.mgh.harvard.edu.
raidsrv01.nmr.mgh.harvard.edu has address 172.21.21.35
