Access denied in http:\\companyweb
One thing to watch out for. Perhaps you are changing user permissions in SBS. Maybe a user now has a laptop and wants to use VPN. You use the change permissions link in Server Administrator to change the user from "User" rights to "Mobile User" rights. However, after doing that the user gets an access denied error on http://companyweb.
Try this:
Open the Companyweb main page, go to Site settings -> Under Administration, click Manage Users -> see if the user is listed. Perhaps he's been entirely erased and you'll need to add him fresh. That should fix your error.
