问题
I just created a new web application that accepts some form based input from the user and inserts it in into the database. To go along with this I created a new user in the database and initially assigned the user to two roles and schemas ...
db_datareader
db_datawriter
After thinking things over I realized the user did not need to be part of the db_datareader role because the user only inserted data into the database and never read any. So I went back and removed the role of db_datareader and noticed that the schema options were grayed out. I could not remove the user from schema ownership of db_datareader.
How does one go about removing a user from ownership of a specific schema? Should I have even assigned schema ownership in the first place?
I am logged in as administrator of the SQL Server and of the Windows 7 OS.

No, you shouldn't have assigned ownership of the schema to the user. You should have just made the user a member of the schema. Revert ownership to dbo and check that the user account is not still a member of the schema.

I had same issue today and found a way to remove user as owner of schema. Open Schema node below Security in database and change the owner for the user that you mistakenly used with the default owner. For example if some oddball user name is listed as schema owner for db_datareader, change it to db_reader and so on.
