Every once in a while we run into a situation where one service or another doesn't seem to get their designated port for listening.
When a port conflict happens, we use a Microsoft tool called PortQry to diagnose which service is jumping in on the port before the service that needs to use that port.
KB 832919 New features and functionality in PortQry version 2.0 explains the full features and their use for the command line version. About 3/4 of the way down is the PortQry local explanation.
KB 310099 Description of the Portqry.exe command-line utility. A brief description of the utility and its features.
The download: PortQry Command Line Port Scanner 2.0.
There is a GUI for the utility, though we don't really use it. It can be found here: PortQryUI - User Interface for the PortQry Command Line Port Scanner.
This is a required troubleshooting tool for our technicians.
