Question : Overwriting Hosts file in Vista

With Vista, I am receiving an Access Denied error message when I try to run a batch file that overwrites my hosts file.

Here's some background.  I use my computer at work and at home.  At work, I access the internal web server via a 192.168 IP address.  From home, I use the public IP address.  In my Favorites, I have a number of links to pages on the web site.  Rather than creating two sets of favorites, with different IP addresses, I edit the hosts file to change the IP address of office web server, using either the internal or external address as needed.  I have written a batch program to automate this.  I pass in a parameter, and then copy one of two files, hosts.home or hosts.work, overwriting the previous hosts file.  The batch file and the two template files are located in the drivers|etc folder.  

This method works fine in XP, but does not work in Vista.  I have checked that I am an Admistrator.  

c:\Windows\System32\drivers\etc>copy hosts.home hosts
Overwrite hosts? (Yes/No/All): y
Access is denied.
        0 file(s) copied.

Does anyone know a workaround or an equivilent way of changing the hosts file.

Thanks

You never "run" as admin... you run in a lower context and get prompted to elevate. The problem here is that notepad doesn't request the access. You have to run notepad as an admin... right click and runas.
