I emailed the admins and they said they "removed the old IP address"
from the WINS server and that seemed to fix things.

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.

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 MRIRESEARCH<1b>
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. The old IP is definitely not in /etc/hosts
anymore or anywhere in smb.conf. It only shows up in
gencache.tdb in the files /var/lib/samba even though I keep
deleting that file when I restart.
WINS is a total mystery to me. How is this supposed to work?

So the WINS server is definitely the problem? When I talk
to them and
mention I am using Samba on Linux they may totally just say
"we don't support it" and hang up.
It seems a strange design that a WINS server can take
precedence over
my explicit "password server" setting in my smb.conf file.

What is the WINS server running OS wise? Can you work with the IT
Staff in charge of that WINS Server?

I am not running winbindd on the server. I am using the
WINS server
of my hospital which I have no control over.
I have already tried deleting browse.dat (I do not see
the other two
files anywhere) to no avail.
So my fear is that this is all happening because the WINS
server is
refusing to recognize the change since I cannot do anything about
it. Is that the issue? Is there anyway to force a WINS server to
change the IP it has a for domain master browser?

It's most likely that your server has the old IP Address
Cached in the
wins.dat, browse.dat, browse.tdb.
I recommend the following:
Shutdown the windbind, nmbd and smbd services.
Back up each of the above mentioned files.
Delete the original above named files.
Restart your services and then see if you can connect.
You may also need to edit your samba configuration file
to point to
the new server IP Address as the PDC Master Browser.
(Assuming you
didn't already do
that.)
The problem is that your server is telling clients to
attempt to find
it on a network that no longer exists.

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
