The PA may have detected a threat or a file type that you are blocking or QOS may be throttling the session (that is if you have QOS configured). To aid in isolating you can create a policy for these sessions and not add a profile to the policy. If the downloads are still stopping, you can call in to support to aid in troubleshooting this.

thanks,

Are you using IE browser to download the MS-Update? If you are then can you please try firefox or Chrome, as I have seen this issue when IE was used to download the MS-Update.

Hope this helps.

Thanks

Hi mrajdev,

microsoft updates are usually triggered by the operating sytem, so no browsers involved.

Hello Bhav,


Can you confirm via Monitor->Traffic & Monitor->Threat whether discards/resets/drops, etc... are occurring during the time of the updates?


You could also manually launch a windows update from the client (Browser or Start->All Programs->Windows Update), then either filter the source IP of the client via the WebUI/Monitor Tab ( addr.src in x.x.x.x ) or via a session trace from CLI:


show session all filter source <ip>

(Keep pressing Up Arrow & Enter & verify session status ACTIVE, DISCARD, etc…)


You can also apply a similar filter to the URL filtering logs as well in the WebUI (Monitor->URL Filtering) as you may have a blocked category that happens to be hosting content (i.e., content-delivery-networks) that is being referenced/pulled from an external sites during update downloads.


Regards,


Bryan

Hi Bryan,

Thanks for the update. i have now allowed everything through a single server, which will then deploy updates to the rest of the PCs...

thanks for the response again.

Cheers

Bhav
