AD is on 2k3 SBS, I have a 2nd box running 2k3 standard for sql server.  Can I run dcpromo on the 2k3 standard box to create / duplicate my AD.  Currently if my SBS is offline my users can't get on the network.  Hoping dcpromo on 2k3 standard will allow them access to the network.

Yes, you can do that.
Make the new DC a DNS server and a Global Catalog, but do NOT transfer any FSMO roles to it, otherwise your SBS will shut down.

Oh, and just in case your new DC is R2 and your SBS isn't, you need to run another "adprep /forestprep" from the R2 CD before you can dcpromo the new server:

Understood.  I suppose the nic settings on each workstation should have the new DCs ip as a secondary dns?

Exactly, otherwise the new DC would be of no help at all.
On a side note: if your current DNS zones aren't AD integrated yet (properties of the zone), change the zone type to AD integrated before you run dcpromo on the new machine. Then you'll only have to install the DNS service on the new DC, the zones will automatically be replicated.
