Diclaimer: I'm computer literate but my experience with servers is close to NULL Working with a server & router with a handful of local machines running XP Pro. I need to add users to the Domain. So, do I need to access the server from a local machine using the IP (like I would a router) then use the Admin credentials to access the Administrative Tools offered in Server 2K/2K3? Or am I completely missing something simple? Thanks in advance!

You're completely missing something. :) XP Home doesn't have the ability to connect to a Domain. What version of Server do you have? Did you set it up as a Domain with AD? "So won’t you give this man his wings What a shame To have to beg you to see We’re not all the same What a shame" - Shinedown

Thank you for the fast response, however.. I'm not using XP Home, just posting from my private machine. The machines in question are using Xp Professional. I'm working with a pre-existing Domain & Server. The company I am working for had a consultant set it all up, but we've come to the point where we're expanding and want some minor changes in the Domain. I happen to be the most technically inclined on the staff and if I can get into the settings I can do what needs to be done NP (that sounds kind of sad lol) To answer you question though, I'm not sure which version of Server is loaded, all of the local machines are on XP Pro.

If you're just adding machines to an existing domain, and your user account has Domain admin rights, or you have the Admin account login you can on the XP Pro Machines select: START > Control panel > System > "Computer name" tab then add the client to the domain by selecting "rename this computer or add to domain" and type the domain name in the following screen, it will ask you for authentication and then create an account for the machine on the server.

Exactly. And, buy a book. You'll need one. "So won’t you give this man his wings What a shame To have to beg you to see We’re not all the same What a shame" - Shinedown

Hehe, again, thanks guys/gals for the timely responses. I have previously added machines to the domain without issue. My problem is Creating an Managing user accounts on the Domain. Which I know about the Administrative Tools options, etc. I read up on how/where to do what I need to do. It's just that, I simply can't access those Administrative Tools windows from the XP Pro machine, when logging in with the Domain Admin credentials. So, I was wondering if I had to access the Server via IP to do that? Like I would with a router (just more involved) ?

You'll need to install the Admin Tools on your XP Machine. Or, run mmc and add the Active Directory Users and Computers to the console. "So won’t you give this man his wings What a shame To have to beg you to see We’re not all the same What a shame" - Shinedown
