I am not able to perform a windows update on any of my computers. This includes my Windows 2008 R2 server and all of my workstations (windows XP, Windows 7).
the error that is always returned is:
Windows could not search for new updates.
An error occurred while checking for new updates on your computer.
Code 80072EFD - Windows encountered an unknown error.
This happens whether or not I have my firewalls on or off (am only using the Windows firewall). I also have Trend Worry Free Business Security and it happens when I have this turned off.
