Joining 2 windows 2003 (standard) servers over a WAN

we would like to join 2 windows 2003 servers together over a WAN.

Does anyone have any detailed instructions on how to do this? I have not connected any together before and would like to be able to do this.

Any advice greatly appreciated.

Many thanks.

Having read the question again, I thought I should provide some additional information.

The 2 sites are in the UK, but in different cities. both have a high speed internect facility. I would I have Exchange running at site 1 and would like to provide a connection so that we can have access to the mail server from site 2.

Would site 1 be the only domain controller, or is there some kind of replica required at site 2?

Do we need both sites to work using the same local domain name, and how is DHCP configured? Do we have the same IP address subnet at both sites.

I would like to have an understanding of what is required to facilitate this, as so far I have only dealt with stand alone servers, so if there is any step by step instructions anywhere, I would love to see them.

Many thanks.

That is a big topic :-)

You would normally join the two using two VPN capable routers.  The established tunnel makes connectivity seamless.

Both sites MUST use different subnets for routing to take place.

The servers would normalcy be members of the same local domain (simpler), but they do not have to be, you can set up a trust relationship between the two.  You also configure active directory sites and services for the two sites, subnets, and servers.

You only need one domain controller but all machines, members of the same domain have to authenticate to it and use it as their sole DNS server.  This can slow performance a bit and if the VPN goes down, users on the site without a DC cannot authenticate (except using cached credentials) and will have no Internet.  A DC at each site is recommended but certainly not necessary.  It can be a Read Only DC.

DHCP is handled locally by router or server (recommended) however DHCP must assign your DNS server/s as its only DNS server, you cannot add an ISP or router as an alternate.  It must also hand out the domain suffix.
