Force drop an MSSQL login?
<p>I can't drop a newly created login, as the server keeps throwing the "Could not drop login '(..)' as the user is currently logged in. (Microsoft SQL Server, Error: 15434)".</p>

<p>The login was created a few minutes earlier and used once from a .NET web app, the web app has been shut down (the whole IIS server is stopped), the SQL server has been restarted several times and the session table is empty.</p>

<p>What could be causing the server to still think the user is logged in, and how can I fix it?</p>
