Windows update returns error 0x80240022 unless Firewall switched off RRS feed

  • Question

  • Win7 64 bit. New, clean installation. No 3rd party security software (firewall or virus scanner).

    Hi all

    I've been try find a way to get my system to update with firewall on for weeks. I have trusted sites set and have run the cross-your-fingers-and-hope general fixit. I subsequently discovered firewall on, run update either from the update applet or Security Essentials, the update process would run so far then do nothing until I switch off firewall. As soon as firewall is turned off, updates begin to download.

    Event log carries entries similar the the following (NB www.download.windowsupdate.com is set as a trusted site):

    _____________________________________________________________________

    Name resolution for the name www.download.windowsupdate.com timed out after none of the configured DNS servers responded.

    {Not sure if this is related but I am seeing quite a few:}

    Name resolution for the name dns.msftncsi.com timed out after none of the configured DNS servers responded.

    {This is the typical error when it fails to update - very unhelpful, other than it points to an update issue}
