Cannot remove dbo rights from a user

In the login properties on the Database Access tab, a user's name says
dbo instead of his name. I do not want him to have dbo permissions. I
cannot drop the db_owner permissions that he has on the database
because I get the error "Error 15405: Cannot use the reserved user or
role name 'dbo'."

How do I remove these permissions from this user?MK (mhedblom@.libertysite.com) writes:

Obviously this person is the owner of the database. If you don't want
this, use sp_changedbowner to make someone else the DB owner.

did NOT have him as the owner. It showed the owner as our system
account. However, I ran sp_changedbowner anyway just as a test and it
removed his alias'. Strange but thank you so much!

Have the database been restored/attached from a different server
instance?
