Good plugin

It works as expected but does not work out of the box on Windows 2008 R2. In order to get past the “MSSQL Critical – Error: Provider cannot be found…” you need to install the SQL Server 2005 SQL Native Client. This can be found here: http://www.microsoft.com/en-us/download/details.aspx?id=17943

The problem basicly is that check_mssql_nt looks for SQLNCLI.1 but on Windows 2008 R2 this has been replaced by SQLNCLI10.1. By installing the SQL Server 2005 SQL Native Client the SQLNCLI.1 version is added so that the plugin can use it.
