We run a windows 2003 server domain.

We have two sites, site A and site B. They proper routes are setup between them.
Each site has 1 domain controller.

If the domain controller in site A goes offline, users are unable to login.

I would like to change it so that if the domain controller in site A goes offline, users are still able to login using the domain controller over at SITE B.

How do i make this change?

That should happen by default, are both DCs global catalog servers?  Are you running DNS on both servers and are clients using both IPs in their DNS configuration.

You say the route is setup so I'm assuming no firewall/port issues.

Thanks

- No firewall / route issues
-Both run a DS server

-Clients @ site A only have site A DNS server, not SITE b DNS server as well.

Could that be problem?

Yes, add the site B DNS server to site A's clients (add it as secondary).   Do the reverse for site A.

Thanks

Any way to test without having to take site A DC offline?

Not sure if it is. Unless you mess with the SRV records' weight. But I am sure Mike may have an alternative.
