.SYNOPSIS
This script is used to discover Microsoft SQL servers without port scanning.
SQL discovery in the Active Directory Forest is performed by querying an Active Directory Gloabl Catalog via ADSI.
Discover-PSMSSQLServers
Author: Sean Metcalf, Twitter: @PyroTek3
License: BSD 3-Clause
Required Dependencies: None
Optional Dependencies: None
Last Updated: 2/04/2015
Version: 2.3
.DESCRIPTION
This script is used to discover Microsoft SQL servers in the Active Directory Forest.
Currently, the script performs the following actions:
* Queries a Global Catalog in the Active Directory root domain for all Microsoft SQL SPNs in the forest
* Displays the Microsoft SQL server FQDNs ports and instances
* Identifies any service accounts associated with the SQL instance and includes the account info
REQUIRES: Active Directory user authentication. Standard user access is fine - admin access is not necessary.
.EXAMPLE
Discover-PSMSSQLServers
Perform Microsoft SQL Server discovery via AD and returns the results in a custom PowerShell object.
.NOTES
This script is used to discover Microsoft SQL servers in the Active Directory Forest and can also provide additional computer information such as OS and last bootup time.
