User can't RDC login after uninstall of active directory

I had 5 user accounts setup yesterday but didn't have active directory installed on the server.  I had to install it for a software package my company purchased.  After a few hours of not being able to get the software to install correctly, I decided to start over.  I uninstalled active directory and in turn, it removed all my user accounts.  It create a new admin account called administrator.dallas1.  When I used to RDC for the username I had to put DALLAS1/username.  Now I don't need the DALLAS1 and I can even just put something random in and it will still connect, like BOB/username.  The administrator account still logs in, although my desktop is changed, all icons are removed, etc.

Like I mentioned earlier, when I uninstalled the active directory it removed all users.  So I created a new user to test and now that new user can't RDC into the server.  I do not have terminal services installed and didn't beforehand either.  I have the user in the Remote Desktop Users group.  

The error that I am receiving is this:

To log on to this remote computer, you must be granted the Allow lon on through Terminal Services right.  By detault, members of the Remote Desktop Users group have this right. If you are not a member of hte Remote Desktop users group or another group that has this right, or if the remote desktop user group does not have this right, you must be granted this right manually.

Anyone ever experienced anything like this?
