Could not register HTTP URL with WCF

Just had the following error:

HTTP could not register URL http://+:8000/. Your process does not have access rights to this namespace (see for details).

when trying to run a Windows Service that listens on localhost using HTTP protocol. This happens on operating systems >= Vista, meaning the Windows 2008 is affected. The solution (listed here) is to run the following command as Administrator:

netsh http add urlacl url=http://+:8000/ user=DOMAIN\UserName

Now, to execute the same thing in older operating systems (Windows 2003, for example), you would run:

httpcfg set urlacl -u http://+:8890/ -a D:(A;;GX;;;S-1-5-20)

Then check the results with "httpcfg query urlacl". Replace "set" with "delete" to remove the permissions. Given SID is for NTAuthority\NetworkService.
