C# – WCF ServiceHost access rights

Unfortunately the link in the exception text, http://go.microsoft.com/fwlink/?LinkId=70353, is broken. However, it used to lead to http://msdn.microsoft.com/en-us/library/ms733768.aspx which explains how to set the permissions.

It basically informs you to use the following command:

netsh http add urlacl url=http://+:80/MyUri user=DOMAIN\user

You can get more help on the details using the help of netsh

Gives help on the http add command.

What netsh command did you run?

netsh http add urlacl http://+:4711/ user=DOMAIN\USER

On your machine, the built-in administrator account has implicit ownership of all HTTP namespace reservations, so you need to delegate ownership of the specific namespace reservation (like above) to the target account that will be running the HTTP endpoint. You do this by ensuring you Run as administrator before performing the netsh command.

To check what namespace reservations are in place, run:

netsh http show urlacl
