On Vista and Win7, run the following command from an administrative prompt:

netsh http add urlacl url=http://vaidesg:8080/ user=everyone

For XP, first install Windows XP Service Pack 2 Support Tools. Then run the following command from an administrative prompt:

httpcfg set urlacl /u http://vaidesg1:8080/ /a D:(A;;GX;;;WD)
