Yet another case of can't share folders or files - Windows 11 Pro


Interesting. I just fixed the problem by changing the fixed IP address of Ascthrifter1 to 172.16.103.190 from 172.16.103.190 to match what ipconfig /displaydns showed me.

I also set DNS servers to 192.16.103.1 and 8.8.8.8.

Prior to this, no matter how many time I ran ipconfig /flushdns the local DNS server at 172.16.103.1 never returned the correct IP for Ascthrifter1 which was set to 172.16.103.192. Changing it to .190 has resolved the problem, at least for now.
What kind of network are you using? Is it a home or business network. If it is a home network then everything should be set up automatically.

It was setup for automatic, didn't work so I set fixed IP addresses on both systems and added Google DNS as a 2nd DNS server. Still didn't work until I found the local DNS was returning the wrong IP address for Actserver1 as I showed. Changed it's fixed IP to match what the DNS said it was and all now works correctly.

Nothing I did could get the local DNS server to forget the bad IP address so assigning it to Actserver1 resolved the problem. Weird but I'm happy.

I just checked a VM with Windows 11 Pro 21H2. Advanced Sharing Settings is not available on a computer with 21H2. You need 22H2 for that. What are the specs for your computers? Are they both fully compatible with Windows 11?
No, neither are fully compatible. I had to use Brink's registry patches to get Win 11 to install on both.
Actserver1, the one that I was having problems with was originally an upgrade that I did a clean install of two weeks ago. It runs Pro.
Actserver2 is still running an upgrade from Win 10. It runs Home. I don't see how to get it to 22H2.
