Port Queryv2 is an invaluable troubleshooting tool and definitely should be a standard in your
server toolkit.
If you use PortQueryv2 frequently or you have to teach junior administrators how to use it a little
too often, you might want to consider the graphical user interface add-on called the PortQueryUI
tool. It is simple to install. Download the PortQryUI.exe installer, and double-click it. It will
install the necessary files to a folder called PortQryUI on the local drive. Then simply navigate to
the PortQryUI folder using Windows Explorer or the command prompt, and run the PortQueryUI
.exe executable. The interface is easy to use, and it has convenient predefined queries for common
services and a means to specify your ports manually. For easy access, you can create a shortcut to
it on the Desktop, which is what I do.
To use PortQueryUI to check whether any services are listening to port 9876, just specify the port you
want to check, make certain you are checking both TCP and UDP, and click Query. It will generate
the same report that the command-line PortQuery tool did but in an easy-to-use interface. Check
out the predefined queries for hours of fun.
10. To make it easier to remember, I am going to specify a custom port for Central
Administration that I made certain was not being used by the server already, 9876
(to do that, you need to check Specify Port Number in order to activate the field).
At this point, you can keep the default (just make note of it), or you can enter your
own custom port number (after verifying that it’s not being used by the server for
anything else).
