In order to do so you will need to raise the trust level for your local
intranet to Full Trust, to do so, head on over to your Control Panel, and
inside of the Administrative Tools group you’ll find the Microsoft .NET
Framework X.Y Wizards (where X.Y) is the version of the framework you have
installed that you want to configure.

Once you’ve found it, open it up and when prompted choose Adjust .NET
Security. Next you choose between having the changes you will make soon be
made just for the current user or for the system. This choice is up to you
depending on your needs.

When you’ve made your choice, hit Next and choose Local Intranet from the
available zones. Next, crank the slider all of the way up to Full Trust and
hit next.

Finally, hit Finish to exit the Wizard. Now your security settings will
allow .NET apps to be run on your local machine over the local network.
