Remote Desktop is not the same as the WHS administrator's console application. To use remote desktop to log in to your server directly, on Vista:
- Click the start button, then type 'mstsc' in the search box and press Enter.
- Enter your server's name (probably SERVER or HPSERVER) in the first window and press Enter.
- Enter the user name 'administrator' and the password you created for the console in the next window and press Enter.
Read the warning that pops up, then close Internet Explorer. There is a link on the server desktop that will let you access the shares, open that link and run the update.
Be aware that this is an unsupported method of accessing your server. There are tools available to you that can severely damage your server's functionality, right up to data loss. You don't have to install Power Pack 1 right away; it will be available as an automatic update in August.
