Split Domain into two

[Lukey]

Hi, I currently have one Domain. One of the floors on our office has been bought by another company and there is now a requirement to have two separate domains. They are going to be on two separate IP Ranges but will both need access to some shared resources. I have two questions.

1) To enable me to have two DC's existing on the same LAN, will I have to put a router between then so that the clients know where to get DHCP addresses etc. or is there something else that I can use. VLAN perhaps ?

2) Is there any way that I can migrate user accounts from one DC to another as I have about 60 users to move and I guess that I will have to setup all of the PC Domain profiles again.

Any help much appreciated

Thanks

Lukey to answer your first question. You can setup a new domain as a seperate tree in the Active Directory Forest. While seperating then with the VLAN or router would be a good idea it is not a necessity.

What you would need to do when setting up your DHCP scopes is to create different class distinctions for each domain. Then when you join a computer to either domain use the ipconfig command with the /setclassid option to bind that computer's NIC to the desired domains class. By doing this you will ensure that the GPO's for each domain will pull down correctly to each client.

Here's an example of how to set the class id for a domain named blah with the default name of Local Area Connection for the NIC.

ipconfig /setclassid "Local Area Connection" blah

Note that you will have to use the quotes so that the entire name is read. If the quotes are not used it will try to bind a NIC named Local to the Area domain and you would received an error.

For your second question read up on the movetree, netdom and the ADMT utilities.
