Deleting Domain User Accounts, Profiles, And Files

Im a new user of Windows 7, just turned it on for the first time a few days ago, but Im pretty familiar with the setup since Ive used Vista for over a year now. This Windows 7 machine that I just turned on a few days ago is a new work machine for another employee here at my place of work. Ive gone ahead and already added it to our domain, and I�ve signed onto it using multiple user accounts that were created in our Active Directory. My question is, how can I go about deleting those Domain User Accounts, Profiles, and Files off of this Windows 7 computer? Ive already made the mistake of deleting the user folder in the C:Users folder, just to find out that if I deleted a user and tried to sign back on as that user (thinking it would create a new profile folder in C:Users), it created a temporary profile.

In the past when using XP all I would normally have to do is delete the user profile folder in C:Documents and Settings and I was able to sign back in as that user and have a new profile created.
