I struggled for this for a few hours, so in case anyone else has this
problem in the future:
I just switched over a network from public IP addresses to a private
subnet (10.100.X.X). After which and I started having problems with our
NT Workstations accessing the Backup Domain Controller.
So, I looked at the config for our BDC and everything looked fine,
except whenever I tried to use any net rpc commands I would always get
the "Unable to find a suitable server" error (couldn't rejoin the
domain, etc). Upon further investigation I also got those errors on the
Primary Domain Controller !?!
All the while, all of our Win2K and WinXP clients worked perfectly. So,
knowing that when working with a mixed winnt/win2k/winxp network that
the WINS Server had to be specified in a win2k server/clients for any
winnt clients to access them, I re-read the Network Browsing Chapter of
the Samba How-to Collection.
It turns out that the WINS Database on the PDC still had the old IP
Addresses of the PDC and BDC. So, I stopped the nmb service on the PDC
and deleted the wins database and restarted nmb - everything once again
started working as it should.
Hope this helps a future problem for someone,
