linkedserver errors when you drop and add it

Posted on 2012-03-23
Last Modified: 2012-03-26

my script contains

Drop user linkedserver
Create User linkedserver For Login linkedserver
Exec sp_addrolemember 'db_owner', 'linkedserver

Then I got the following error:
-Cannot drop the user 'linkedserver', because it does not exist or you do not
have permission.

I changed my script to
IF EXISTS(SELECT * FROM sys.database_principals WHERE name = 'linkedserver')
          Drop user linkedserver

and then to
IF EXISTS(SELECT * FROM sys.database_principals WHERE name = 'linkedserver')
          Alter authorization on schema::linkedserver to dbo
          Drop user linkedserver

However, it seemed to work for one db but caused another error on a different db.
The errors I am getting are:
-Cannot drop the user 'linkedserver', because it does not exist or you do not
have permission.
-The database principal owns a schema in the database, and cannot be dropped.
-User, group, or role 'linkedserver' already exists in the current database.
-Cannot find the schema 'linkedserver', because it does not exist or you do not
have permission.

How should I reconstruct my script to resolve all the issues I stated above at the same time?
Plz help~
