Adding windows 2003 small business server to existing network

I am adding a win 2003 SBS to an existing network of 20 seats which is currently running with a win 2000 server as domain controller.  That machine will remain on the network running some file sharing and a mssql application which is our most critical application.

So I understand that the new machine will have to become the primary domain controller.  I guess it will also take over dns.

Can anyone help me out with some ideas about how to approach this addition to the network.  I have found many resources on upgrading howeve this is a bit different I think.

Thank you very much.

You CAN'T do this! You can't add SBS to an already existing domain.

"So I understand that the new machine will have to become the primary domain controller"

Well you're sorta on the right track, but you have to understand that you can't add SBS to an existing domain. The SBS has to be the first domain controller in the domain. There isn't an "upgrade" path to upgrade from a standard server to an SBS....in fact, in a sense this is more of a downgrade.

Anyway, basically you need to start over. You'll need to setup the SBS as if your current domain didn't exist. I'm also not sure aboout transferring your user accounts since SBS doesn't support trusts...maybe someone else can offer you some more detailed advice about that.

Are you currently running exchange or sql?  What was the reason that you went with SBS instead of just buying 2003 standard edition?

Thanks for that information.

The reason that we are adding small business server is that we currently don't have exchange but also that we want to use the remote access functions that are part of it.

I can see that it is going to be a mostly manual process, which I agree is a bummer but it is a small network and I don't think it will be that bad.

Now I am not that experienced with networks that have more than one domain controller, so will I be able to eventually have the existing win 2000 server be some kind of secondary domain controller, or is that even necessary?

Thanks again for your help.

In an 2003 SBS network, you can have other domain controllers (they are not called primary or secondary as those are terms from the old NT days and in 2000/03 all domain controllers are considered equal). The limitation (one of them) with SBS is that the SBS must be the first domain controller then you can add others in, but not vice versa. You also can't have 2 SBS servers in one domain.

So you shouldn't have any issues with adding the 2000 server as a DC to the SBS network once you have the SBS domain setup and running.
