We have Windows 10 laptops and Surfaces that experience this issue. When the laptop is in a workgroup, they appear to not experience the issue. The issue also does not always occur right away. Once the Windows 10 PC is joined to the domain, it works fine in the office. When they take it out of the office, it won’t connect to WiFi.
We have run the following commands as suggested in the forums, but they have not solved the issue.
netsh winsock reset catalog
netsh int ipv4 reset reset.log
netsh int tcp set heuristics disabled
netsh int tcp set global autotuninglevel=disabled
netsh int tcp set global rss=enabled
sc config NlaSvc start= delayed-auto
We have tried removing the WiFi hardware from the Device Manager and rebooting.
We have tried updating the WiFi drivers.
We have tried running a ‘Windows Refresh’, and a ‘sfc /scannow’.
When we run the troubleshooting, we get the following message…
‘Windows does not have a valid IP configuration and it was not fixed’
There are no WiFi policies on the domain. There are no encryption settings in Group Policy.
From our testing the PCs do not obtain an IP address and the networking shows ‘No Internet, Secured’.
We have worked with both Sonicwall and Microsoft and they have been able to confirm that the DORA request is not being handled correctly by the Windows 10 PCs.
The only solution we have so far is a complete reload of the PCs, but this is not a workable solution.

Moved to Networking, as this is a networking problem that happens to be occurring under Windows 10
