I put together a small WCF service in VS2008 and when I try to run the host using an HTTP protocol, it bombs because it doesn’t have the proper rights to do so. On my ‘Host.Open()’ line I get this exception: ‘HTTP could not register URL http://+:9001/. Your process does not have access rights to this namespace.’ I did not seem to have this problem using TCP. My o/s is Vista Home Premium.
This was happening when I would try to Debug it inside VS2008. After a lot of research, I determined I could get the host to run by building, going to the ‘bin’ folder, and right-clicking on my executable, selecting ‘Run as Administrator’. The same thing happened when I tried to use the WcfSvcHost.exe. I had to open the VS2008 Command Prompt window from my menu using ‘Run as Admin’ before I could successfully get WcfSvcHost to run my service.
Is there a way to do this right instead of using this workaround? Am I going to have similar problems when I try to deploy this next week on a Windows 2003 Server?

Short version: pre-register the url/namespace from a privileged console
netsh http add urlacl url=http://+:9001/ user=DOMAIN\user
