i am wondering if someone can help me with a exchange server prob. i have all of what i need but i need help being undetected.

Please give us some more details.

by knowing the proper login/domain and password, can a admin still tell were the login was originated.

er... If you are wondering whether an admin can tell who has been on an account and when...then the answer is obviously...yes. If you are worried about it, then spoof your IP before you login. I don't see why the admin would bother checking unless he has a complaint from the person who owns the account. If you are talking about logging into an admin account, then the admin will probably find out someone was on it, but as long as you fix the logs, cover your footprints, and don't do anything stupid (ie. dont send out e-mails all across the world to your buddies to show them you are cool cos you rooted a box) you should be fine.
