Setting up new domain, but keeping old simultaneously

[Trana]

Hi,

I am about to setup a completely new domain replacing the old server and domain with a new one handling everything for the company (DC, DHCP, DNS, file/print server, backup etc). The company is so small there is no need for separate servers for any of these roles. The disks have RAID1 which should be sufficient with backups to tape as well.

Now, my question and problem is, the company that I am doing this for is currently sharing their domain and server with a sister company, they are to be separated now when I install the new domain, but they are still on the same physical network. How can I separate the new domain from the old without causing problems for the sister company?

I mean, for instant I can’t have two DHCPs on the same physical network right?

Any input would be greatly appreciated.

I'm sure you can. Just don't overlap the scopes.
Or get a switch with vlan's

I forgot to mention that the new server is SBS 2003.

When running setup I get stopped at:

-----
Setup detected an existing DHCP server. To use the DHCP server provided by SBS, the existing DHCP server must be disabled.
-----

Now, again, I do want to run DHCP for my company on my server, but I also wish to leave the sister companies DHCP in place. Any thoughts?

Unplug it from the network to set it up, then plug it back in. Be sure your new network/domain is using a different subnet than the existing one and you'll be fine.

There are no more PDC's! There are DC's with FSMO roles!

Thanks for the quick reply Davetoo, but if I dont have a network connection the SBS setup wont let me start.

Did you mean, run setup up until the "setup has detected an existing DHCP server", then unplug it and continue with the installation?

Just plug it into an otherwise empty switch.
