Windows 10: Windows 10 Activation with limited internet access (Firewall).

Short description: If I run slmgr -ato when using a direct connection to the internet the device is activated, if doing the same from the network with limited internet access activation fails.

What sites/urls/ports must I allow to be able to activate Windows from our limited access network?


In a lab at work we reinstall all our Windows 10 machines using a custom image that contain all our apps and settings.
All devices are manufactured by Dell.
The lab have a very very limited connection to the internet allowing only a handful of sites on the internet.
I did find some knowledge (links below) and allowed all those sites for http 80 and https 443 but activation still does no work.

If I connect the same device directly on the internet and run slmgr -ato activation is successful.

We allow per host using pfsense, so urls are not used, it's the actual hostnames like go.microsoft.com
The lab is portable and also split in many parts and locations, this one lab is the main location and from here devices are shipped to other labs as needed, in many cases in location where the internet or anything else does not exist, like the arctic...

My guess is that one or more of the hosts redirect to somewhere that is not in the list - thus making the list or required hosts are incomplete.
I have tried to allow all protocols and not just HTTP and HTTPS and makes no differance.

Limited internet access.

After I upgraded to Windows 10 my internet access is only limited. How do I restore full functionality? Thanks for any insight or suggestions.

 

does active armor firewall block windows update

did you try and open the way for windows update to work? You may have to allow it to access the internet. I honestly dont have experience, yet, with Asus Armor Firewall, but I have firewall experience and you might have to do that. Probably put it in the internet or trusted zone, or maybe even open the ports up.

 

Windows 10 - WiFi Limited/No Internet Access

I had the problem with "limited access" wifi. It was after a win 10 update. After trying all of Microsoft fixes I turned off my AVG firewall. WOW!!!!!!!! internet access. Win updated again and I could then turn my AVG firewall back on. It's been working
since then.
