Migrating from WINS to DNS.. help please

[Kendal L. Montgomery]

Hello,

My company is trying to migrate away from using WINS and LMHOSTS files, so
we planned on going to DNS internally.  We have our DNS servers up and
running (ns1.mycompany.com and ns2.mycomany.com).  We are running bind 8.2.1
on RedHat Linux 6.1, kernel 2.2.5-15.  Everything seems to run great here at
the corporate office within this subnet, or even at our other plant
locations on a different subnet (corp = 192.168.11.0, other for example =
192.168.5.0).  We are running NT servers for filesharing and Exchange for
email.  With WINS we used to be able to logon to another plant's NT domain
by just typing the name of the other domain on the Microsoft Logon screen in
Win95/98.  When we disable WINS and delete LMHOSTS on the clients and run
pure DNS (network setup is assumed to be correct, with DHCP setting the
correct addresses to the name servers) we can't login from one NT domain
(say, 11) to one of our other NT domains across the WAN (say, 05).  I'm not
sure why we run in to this problem, but I assume it has something to do with
the subnet's being different.  For instance if my computer's ip address is
192.168.11.166 and I want to log in to the NT Domain where the NT Server's
ip address is 192.168.5.2, it doesn't seem to work.  You get an error saying
that "there is no domain server available to validate your login," or some
such message.

I know that for WINS the LHMOSTS file specifies what IP address is the NT
Server for each domain, for instance:
192.168.11.2    NT11    #PRE    #DOM:11
192.168.5.2      NT05    #PRE    #DOM:05

I'm not sure, if my assumptions are correct, that bind provides for your
client to realize that when you want to log in to NT Domain 05 from the 11
domain that you want to authenicate against NT05 or 192.168.5.2.

Just for more background information, we do have the clients set up in
TCP/IP Properties under DNS with hostname: MYNAME and domain: mycompany.com.

If anyone has had this type of problem, or know how to solve it, please,
please email me at: klmontgo at findlayindustries.com

Thank you in advance...
