Around a month or so ago we've been experiencing the 'No Internet Access' network adaptor warning on various machines at work (various Windows OS) and we can't seem to pinpoint the issue - they connect to the Internet fine. It happens on some machines and not others, then for some bizarre reason the issue can simply go away on it's own or appear on new machines. The problem is we need to address this as it affects Office 365 apps.
We've had a good look at how network awareness works, but this hasn't helped matters as we can't see a reason why the NCSI checks would fail (some we've tested manually). We've tried removing AV, resetting the TCP/IP stack on the machine, bypassing our wan optimiser, ensure no proxies are in the way, changing DNS servers, disabling IPv6 settings, disabling local firewall, rebuilding the machine. The only thing it's going through is over an MPLS network and through an ASA the same as other machines which are working fine.
Has anyone seen any issues like this?
