Windows 8.1 not communicate with Server 2012 R2 WSUS 6.3

Narinthorn Sadudee

Hi All,


I have problem with client windows 8.1 pro after config local gpo and recheck in regedit.


When I start windows update that client try to update online not direct to IP WSUS server I saw in resource monitor svchost.exe(netsvcs) try to connect on port 80 (my office connect internet with proxy server but I dont know why or what service can run update without proxy setting). But on windows 7 pro, windows 10 pro boths can communicate with WSUS server and update normally


Thanks for your advice.
