Solved Can't access Administrative Shares

perdrix · Dec 14, 2022

I'm been trying to connect to the normal Administrative Shares on my Windows 11 system from a Windows 10 system. I tried to connect to:

\\Apollo\C$

I get a timeout eventually. I am able to connect to the admin shares on the W10 system from the W11 system.
I did load the classic registry set:

Windows Registry Editor Version 5.00

Code:

[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Policies\System]
"LocalAccountTokenFilterPolicy"=dword:00000001

[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\LanmanServer\Parameters]
"AutoShareWks"=dword:00000001
"AutoShareServer"=dword:00000001

But that didn't change a thing

Did the admin shares get abolished in W11?

Why add those registry values, delete them and reboot your computer, execute net share command from Admin Command Prompt to view all shares on Windows 11.

Without deleting those registry entries which were needed on W10 to enable admin shares:

Code:

C:\Windows\System32>net share

Share name   Resource                        Remark

-------------------------------------------------------------------------------
C$           C:\                             Default share
D$           D:\                             Default share
IPC$                                         Remote IPC
ADMIN$       C:\WINDOWS                      Remote Admin
The command completed successfully.

So the shares are apparently present but I cannot access them from W10.

I will remove those entries and reboot and report back.

See if this helps....

Solved!
I had to turn on "Enable insecure guest logons", as described here.
Apparently it's required on 22H2, but not on 20H2.

Hmm deleting those entries didn't change the output of net share:

Code:

net share

Share name   Resource                        Remark

-------------------------------------------------------------------------------
C$           C:\                             Default share
D$           D:\                             Default share
IPC$                                         Remote IPC
ADMIN$       C:\WINDOWS                      Remote Admin
The command completed successfully.

And here's what I get on the W10 machine:

Userids and passwords are the same, workgroup name is DEVELOPMENT for both if it weren't I couldn't access the shares of the W10 system from W11).This will of course turn out to be something amazingly simple!

FWIW the W10 machine is 21H2.

Can you go to your command prompt and ping your Appolo machine?

Windows firewall on the W11 side is set to allow File Sharing for the network (which is a private one).

As suggested use Ping command to check if Windows 10 can see the shares.

Also execute net view \\ComputerName /ALL command. This command displays a list of domains, computers, or resources that are being shared by the specified computer. Used without parameters, net view displays a list of computers in your current domain.

Also, when I did this ages ago, I seem to remember you had to have same account and password credentials on remote pc as on host. Also at back of my mind, you had to enable smb.

It is just easier to setup your own shares.

It is enabled and user/password are the same

@cereberus, have a good idea, try connecting to share you have setup just to make sure its only hidden shares that you are problem connecting.

Did that, still get:

Code:

C:\Users\amonra>net view \\apollo

Well, I have no issues as I know how to set shares up. I never use the admin share as they were always a bit hit or miss.
