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.

Subject: [Samba] Changed PDC IP, all hell broke lose
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
