Introducing a win2008 server into win2003 AD network

cfgtechs used Ask the Experts™
We have a 2003 server "FS1" in place as a fileserver, domain controller, and dns. This was the first DC in our AD and have since added another 3 servers, an exchange, and couple other machines running sql and .net apps, given DC role as well.

We intend to replace FS1 with a Win2008 R2 machine and eventually down FS1. I want to also give the 2008 the role as a 2ndary DNS, when we down FS1 we'll key in the new DNS to all the clients, about 60.

Will the 2008 server participate/co-AD manage well with the 2003 servers? we have group policy scripts to contend with as well.

i admit that i don't have a lab setting to try this out first, getting a win7 client to see the internet even though you manually plug in the gateway and dns entries is hard enough!

Best to follow the following directions

Adding the new server in wont be an issue, first thing you will need to do is a schema update though

GPO's will all work with 2k8 as they did with 2k3 though you will get lots more options for configuring windows 7 machines

Are you running DHCP on your DC? if so updating DNS on all your workstations is very straight forward


thank you, was looking for this reference, most articles i was pulling up was assuming i would migrate all the 2003 AD's into 2008, we want to just transition one of them.

i did discover we have (1) 2000 server and we're running in mixed 2000/2003 mode because of this box. will move this application into a 2003 machine and then change AD mode into 2003.

we only run dhcp for a few weeks when we have visitors then stop the service for most of the year.
