How to fix: HTTP could not register URL error

Often when running a service , you might get the following annoying error :

HTTP could not register URL http://+:8000/MyWCF/. Your process does not have access rights to this namespace (see http://go.microsoft.com/fwlink/?LinkId=70353 for details).

To get around this you need to run up a command window and run the following for your service and domain :

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


Thanks to Brian via stackoverflow for this command and the explanation of the invalid exception text and how to find what's really going wrong.
