Hello Community

 

I have an issue with Windows update archives which have too many files; it leads to an Avira block log entry 'The archive contains more files than allowed.'.

What max. file count config would you recommend here?

Or would you rather recommend to whitelist Windows updates, i.e. 'download.windowsupdate.com'?

Thanks for your advice. 

Regards,

Raphael

I usually whitelist all the MS domains that are related to updates. Better to leave checking on these files to the endpoint  / server AV IMHO.

Thanks for the input. The issue is still not resolved; what are all the MS domains? I tried several times to collect all involved, eg here: https://support.office.com/en-gb/article/Office-365-URLs-and-IP-address-ranges-8548a211-3fe7-47cb-abb1-355ea5aa88a2

The list still doesn't seem to be complete. Does anybody have a complete list to whitelist for MS activation and updates?

Many thanks,

Raphael

As per https://technet.microsoft.com/en-us/library/bb693717.aspxthere are more domains used by Microsoft for updating:

 

  • http://windowsupdate.microsoft.com
     
  • http://*.windowsupdate.microsoft.com
     
  • https://*.windowsupdate.microsoft.com
     
  • http://*.update.microsoft.com
     
  • https://*.update.microsoft.com
     
  • http://*.windowsupdate.com
     
  • http://download.windowsupdate.com
     
  • http://download.microsoft.com
     
  • http://*.download.windowsupdate.com
     
  • http://test.stats.update.microsoft.com
     
  • http://ntservicepack.microsoft.com

 

As some of the URLs show, it is not quite up to date, but I have created DNS objects for the ones that are noticed in ATP and whitelisted them. Having Windows Updates ATPed creates error messages on my servers and clients from time to time, and I want a reliable patching.
