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} Microsoft Antimalware has encountered an error trying to update signatures. New Signature Version: Previous Signature Version: 1.123.297.0 Update Source: Microsoft Update Server Update Stage: Download Source Path: http://www.microsoft.com Signature Type: AntiVirus Update Type: Full User: NT AUTHORITY\SYSTEM Current Engine Version: Previous Engine Version: 1.1.8202.0 Error code: 0x80240022 Error description: The program can't check for definition updates.

I have installed many Windows 7 operating systems and never met any error caused by update. However, I have aplied chipset driver first after vanilla plain install, then I installed video, lan and audio drivers. When I have device manager clean and no unknown device remained in the list, I started update. Any troubleshooting of updates is based on the content of WindowsUpdate.log and ReportingEvents.log files. Read files from the bottom up. reveal your findings here. Error code 0x80240022 is covered in knowledge base article http://support.microsoft.com/kb/918355/en-us or you automatic update fixit tool see KB971058. Regards Milos

Hi, According to your description, this issue should be related with the firewall configurations. You may refer to the following link to check if it helps: You receive error messages when you use Windows Update through a proxy server or a firewall Also, I notice you have posted this issue before. In order to avoid confusion and keep track of issue, I recommend to keep working with the previous thread as link below: http://social.technet.microsoft.com/Forums/en-US/w7itprogeneral/thread/c832cf48-cbc0-4b49-9b88-d3c23e806e94 Thanks.

Hi Tracy. You are correct. However, there was no response to my updated question on that thread. Also, I now only have a single issue left to resolve - bit its a tought one. The fact that update runs after firewall is switched off is a farily convincing argument that the issue is firewall related. It MUST be a settings problem but I can find no help on configuring firewall Win 7 64 bit. I have none of the Firewalls listed in the link you supplied. I use Win 7 firewall and am not accessing internet via proxy.
