rebuild of DNS and Active directory

I need to rebuild a domain controller in a remote location.

We have two windows 2003 Server standard edition servers in our main site, these servers both have active directory, one of them is a dhcp server and the other is a dns server.

We also have a remte site that has a windows 2003 server standard edition, that is running dns, and active directory. Active directory was synchronizing properly between the sites up until about two months ago. At this time it looks like Active directory has to be resynchronized from scratch.

I think the problem is due to dns not working properly in the remote site.

I believe I must rebuild both dns and active directory on the server.

Can anyone tell me how to remove and reinstall DNS, and how to remove the active directory information and start resynchronizing it with the remote site.

Any assistance would be greatly appreciated.

Thank you

I gave this a try, and now I am, trying to run DCPromo to reinstall active directory but I keep receiving the following error:

The wizard cannot gain access to the list of domains in the forest.

This condition may be caused by a DNS lookup problem. For information about troubleshooting common dns lookup problems, please see the following Microsoft Web sit:http://go.microsoft.com/fwlink/?LinkId=5171
The error is:
The RPC server is unavailable

I am able to ping the active directory domain controller at the remote site, it is also running the RPC Service. I'm stuck trying to get active directory and DNS back on my wondows 2003 server.

Any additional help would be great

Thanks

Yes they are all part of the same domain
There is no firewall between the sites
I removed DNS from the problem server.
How do I add it back in as a secondary site? I thought I was going to add active directory back to the server which would also add DNS back onto the server, but I can't load Active directory, because I cant run DCPromo, because I receive the RPC error.

So I need to have a DNS server at the remote site, which I'm not sure how to configure ?
Then I need to point my old server which I removed Active directory and DNS from to get DNS info from this new DNS server.

Then I will be able to run DCPromo on the old server and it will be able to synchronize with my main/primary site. Will DNS and active directory now be integrated on the old/original server ?

Thanks Again
