I presume this was a SQL 6.5 db originally?

I am logged in with a sysadmin role (not 'sa') so "SELECT USER_NAME();" is dbo.

In Enterprise Manager, when I expand this database, go to Security, I do not see the login of the user that we want to drop.

But when i select the properties of dbo, it shows that the login name is the user account to be dropped.

It is also a member role of db_owner.

Any ideas how to remove the mapping?

thank you
