I've been asked to help with a Vista Ultimate PC that is not downloading and installing Microsoft Updates. If a manual check for updates is initiated the user gets the error "Windows Is Unable To Check For Updates". One update, Office 2007 SP1, has been downloaded but if the user tries to install it Microsoft Update hangs. This problem appears to have come about because the PC is connected to an ADSL Modem/Router which hasn't been able to connect for three months. The ADSL problem has now been resolved. BITS and the Windows Update service are started and set to Automatic. I don't have easy access to this machine but I will be able to examine it in 3 days time and would appreciate any advice that is available.
