Okay, so the server that was getting a 'cannot display the web site' error was fixed by a reboot.
However, I still have a server that when I open 'Files & Folders' in the Configure Backup menu I then get a message that reads 'This folder is empty' instead of showing me the drives to select from.
Presumable a problem with the agent but have uninstalled and reinstalled, rebooted the server several times now, nothing in the Event Viewer.
The only difference I can see between this is that it is 2003 x64 and that it has Exchange 2007 installed.
Help is always appreciated!
