I have to be missing something as I can't seem to make this happen. I have 2 SQL 2012 boxes linked and have tried dozens of methods to delete a user from a database on the other server with no luck. I've tried various methods of "sys.sp_dropuser" and "Drop User".

Am I missing something?

Charlie

You have to drop the user from the instance where that user belongs. You can't drop remote users, that would be a HUGE security issue.

That wprk fine for dropping the user from the master database. Is it possible to specify the database I need?

Thanks for the correction. I did not realize you could drop a user remotely like that.

just a a USE DatabaseName to the command, if the linked server didn't define the context for the database name :

EXEC ('Use SandBox; DROP USER thatuser;') AT YourServer

Very good correct Lowell!

Here's one that is slicker:

EXEC LinkedServer.yourdb.sys.sp_executesql N'DROP USER myuser'



Not the least is this one slick, if any of the items are variable:

DECLARE @sp_executesql nvarchar(1024) = 
quotename(@server) + '.' + quotename(@db) + '.sys.sp_executesql'
EXEC @sp_executesql N'DROP USER myuser'



Key here is that EXEC accepts a variable for the procedure name, and a system procedure always executes in the context of the database from which it is invoked.
