The People Picker Port Tester provides a SharePoint Administrator with a tool to test network connectivity problems between a SharePoint Server and Active Directory. This tool can help the Administrator diagnose and resolve network issues, which contributes to users being able to pick individuals from the People Picker on SharePoint websites.
This is a standalone application intended to be ran from each SharePoint server in the farm in order to test direct connectivity to one or more Domain Controllers within an Active Directory domain. It will provide DNS information, as well as closed and open ports, and performs an LDAP search.
