OK, You may be a newbie, but you've definitely won the game of "Stump the dummy".
If you're talking about this - http://en.wikipedia.org/wiki/Xerver then I think you're not going to be able to reach it externally. Technically servers (as Xerver is described in the wiki article) are a violation of the terms of service (TOS) here at dreamhost.
If you're simply misspelling the word "Server" then we can help you with that as you will likely have a domain associated with your hosting account. That domain is how you contact your server through http.
Pick whichever answer is appropriate to your situation and we'll try to keep helping!
