IP Addressing problems

[Gepeto]

Hi there...

Here is my situation:

We have a network of about 100 nodes in our main office. It is using
IP addresses 128.0.0.0/8 (go figure). It is also still using an NT4
domain, with no PDC.

I have to setup another office soon, and I don't want to put them on
the old NT4 domain, so I was thinking of setting up two DCs at the
main office, and one at the remote office. Now my problem is, my IP
addressing obviously needs to be changed at the main office.

Would it be better to buy a router, set my new A.D. with proper IP
addresses, and then set the new office up and eventually move the main
office to the new A.D domain?

Oh, another note.. this NT4 domain doesn't run either DHCP, DNS or
WINS, so I'll have to do that as I switch...

Gepeto,

How can you have a WINNT 4.0 domain without a Primary Domain Controller?
This is impossible. I am sure that it is simply a 'poor choice of words'.

Also, here is my confusion: is the main office WINNT 4.0 ( as you state ) or
is it WIN2000 Active Directory?

If it is WINNT 4.0 then I might suggest that you consider upgrading to
WIN2000 AD ( if that makes sense for you to do ). I would then add a second
Domain Controller ( under the assumption that you currently have only one in
the main office ). Furthermore, I would set up Sites in Active Directory
Sites and Services so that you can maintain one domain when you add the
remote office [ you would simply have two Sites - Site1 ( the main office )
and Site2 ( the remote office ) ]. You would probably want to consider
having a Site-to-Site VPN ( aka Firewall to Firewall VPN ) between the two
offices as well.

As to your initial question, changing the IP Addressing schematics should
not be that complicated. I would go with either 192.168.x.x or even
possibly 172.16.x.x - 172.31.x.x in your shoes. Not sure why you would have
a public IP Addressing scheme ( you did not mention what type of company you
are. I know that a lot of government-type companies use public IP Addressing
schemes ).

This is just my thought based on what I read. It seems like you currently
have a WINNT 4.0 environment at the main office, though.

HTH,

Cary
