Windows 10: Unable to activate Windows on two computers (0x800704cf)

I cleaning install Windows 10 on almost all the machines in my office, both laptops and PCs.

The entire process has been smooth except for two computers.

These two computers are identical and Windows won't activate on them.

Clicking on Troubleshoot gives the following reuslt:





I have tried searching for the error (0x800704cf) and saw tones of YouTube videos and guides but absolutely nothing has helped.


Anyone got any solutions?
My network is not blocking anything because I have activated 15+ Laptops and another PC on the same network.

Error 0x800704cf in microsoft store

Hi,

As per the error message, your internet connection might have something to do with the error code 0x800704cf. The anti-virus on your computer can also be the culprit here. However, let us not assume anything yet until we isolated your concern. We suggest
that you download and run the Windows Store App Troubleshooter. Once done, check if the issue persists.
You can also check if the Store works in another user account. If the issue
still persists, we suggest to reset the Microsoft Store. Here are the steps on how to do so:

• Press the Windows key + R on your keyboard, the type in wsreset.exe.
• Hit Enter to proceed.

You may reset the Store a couple of times before checking if the issue persists.

Let us know the result of the troubleshooting steps provided above.

 

0x800704cf when re-activating windows 10

Windows activates and deactivates at random. Now I see error 0x800704cf when I attempt to activate a version that was active, and deactivated itself. This is annoying.

 

That annoying 0x800704cf error...


Some additional details: if the client machihne maintains an open Remote Desktop session with FILES machine, all shares on FILES continue to work fine indefinitely. No 0x800704cf errors whatsoever. But once the RD session is over, after a certain period of inactivity 0x800704cf reappears.

There appears to be a definite "keep alive" issue of some sort with network connection between the machines. As long as the connection is active, it is kept alive. Once the activity ceases, the connection gets dropped eventually and then takes 20-40 seconds to reestablish.

I wonder if the router is to blame here somehow...


Using the IP address of 'FILES' instead of the name makes it all work fine, i.e. '\\192.163.1.3\Storage' results in immediate successful access even when '\\FILES\Storage' fails with 0x800704cf . However adding an entry for 'FILES' to LMHOSTS file does not resolve the issue.
