We have a S160 and when we try to run windows updates it scans and shows the required updates. But when we click on to ‘Install Updates’ the download fails. I am attaching the error logs, any help is much appreciated.
although, in the 6.3.3 OS, there's a built-in access-policy URL category called 'Software Updates'. this should catch them too.
windows update seems to use the system account, not the user account. we had to match by IP for these URLs. reading around on here, we also found a suggestion to cache authentication settings for the user (ip address).
