Windows 11 cannot access other computers, but can be accessed by the other computers


As @britgeezer did, I also installed his update and that was all the same.

@britgeezer, where did the update come from? The Insider's Preview channel?
Yes, I opted out a long time ago, but on this one PC it kept pushing me to use 24h2. In fact, it was the only update option.

disable the firewall on mint now that you have run the first command and see if it is accessible
It's already disabled; I never enable it.

EDIT: You know what, I'll wait until the next Patch Tuesday, I think this is a mess that Microsoft would have to address. If not, I'll transfer files either through other computers or the virtual machines. It's never given me problems.

I was searching for solutions on accessing my W11 23H2 Server from my W11 24h2 PC and found this suggestion from "GotNoRice" from a while back. I didn't try it then since I had reverted to 23H2, now that I'm back on 24H2 and still having the same issue I thought I would try it.

Have you tried enabling the non-secure guests setting?
If you haven't already done so, do this:
Using the shortcut key Windows Flag + R, open Run and type gpedit.msc to open the local policy editor.
Navigate to Computer Configuration >> Administrative Templates >> Network >> LANMAN Workstation.
Enable the Enable insecure guest logons setting and Restart.

For me it was the resolution of this situation that also happened to me.
Good luck

That security policy sets the same registry entry I gave in post #34. I had to find out the correct registry entry for that policy because I was working on 24H2 Home.

Bree said:
I recently clean installed 24H2 Home. Against expectations it had the same restriction as Pro, an account with no password cannot connect to shares on any other PC. Unlike Pro though, there is no gpedit.exe to be able to change this.
Windows 11 cannot access other computers, but can be accessed by the other computers - post #34

Yes, that 'Enable insecure guest logins' policy is the correct one to use. My registry edit is identical to applying the policy. I was just surprised that I had to do it in 24H2 Home too (the hard way, in Regedit). MS have said previously that this restriction was only for Pro and above.

The thing with me is that, I already tried this.

For a list of stuff that I tried, refer to the first post of this thread.

But I am glad it works for you!

I wish you the best.

I downloaded the Cumulative Update Preview today, but it didn't fix my problem.

Should I have faith that the update coming next Tuesday might do it?

OK with 24H2 Pro 26100.1742 I had the same problem.
My Windows 10 Pro could access Windows 11 24H2 through my network, however Windows 11 24H2 could not access my Windows 10 Pro or any earlier versions of Windows 11 Pro Computers this only happened since I went to 24H2.
To fix this issue I did both of these changes in Local Group Policy Editor. And Now all is happy including me. I hope this helps.

Computer Configuration, Windows Settings, Local Policies, Security Options
Double click on Microsoft Network Client: Digitally sign communications (always)
Double click on Microsoft Network Client: Digitally sign communications (if server agrees)
Set both of these to "Disabled"
Click on OK.

Computer Configuration, Administrative Templates, Network, Lanman Workstation
Double click on "Enable Insecure Guest Logons"
Set this to "Enabled"
Click on OK.

IMPORTANT!!! Make sure the pc's your connecting to HAS an account with YOUR username, and with YOUR password as an active account. (AND give that user access to the SHARE, and Access to the DATA you need, both!) Do not use accounts without password, or do not try to connect to a diffrent username or password, as that gives issues. IMPORTANT!!!
This worked for me, after struggling with a reformatted windows 11 PC for 2 days. I tried everything under the sun but still couldn't access a shared folder on a Windows 10 machine. I added a new user account to the win10 machine with same username/PW as the win11 user and suddenly everything is good.

I don't understand this tho? I have another win11 PC on this network that can access the shares on the win10 PC, but it doesn't have it's own user account on win10. Why do I suddenly need this?!?!
