To gain control of a SQL instance if the user is an Admin on the machine but not in SQL Server

1.        Stop SQL Server service if it is running. 
2.        Set the start up parameter to “-m”.  Do this in the General tab of the service.  Remember any pre-existing start-up parameters so you can restore to the original configuration later.
  



3.        Start service.

4.       At a command prompt:

sqlcmd
create login Paul WITH PASSORD = 'hello!1' 
go

sp_addsrvrolemember 'Paul', 'sysadmin'
go

Note:  SQL has default strong password policy

5.        Put back to normal user mode
remove -m

stop service
start service

DropObjectsInSchema

This proc comes in handy when you have to purge all the objects in your database, so you can then run a creation script.  It will tell you how many objects it dropped.
