Thank you for all the responses. I found how to change the schema name through management studio. But - When I look at the table it still says

ABC\genn.smith.itemresults

The name of the table is itemresults but I can't get rid of the "ABC\genn.smith." at the front of it. I also don't know why these tables are getting these names. ABC is our new domain (not really ABC, just trying to be anonymous) so users are being moved from OldDomain to ABC. Two people on the new domain suddenly are having tables they create come up with the ABC\first.last in front of the table name.

Any advice on these two issues? Thanks again.
