    Accessing administrative shares

    I have a networked Windows 10 Pro computer A with built-in 'Administrator' account disabled. However, it has a "normal" administrator account named 'Admin'.

    I would like to access administrative share '\\A\C$' from another computer B in the network. Windows asks me for access credentials. I enter 'Admin' and the corresponding password. This results in "access denied" error.

    Hence the question: What's preventing the access?

    My guesses are

    1. (Unlikely: ) Administrative shares are accessible to the built-in 'Administrator' only.
    2. (More likely: ) Administrative shares are accessible to a designated set of users and there's a way to control it. My homemade 'Admin' is not on the list.
    3. (Most likely: ) Network access to administrative shares is completely disabled by default in Windows 10, but can be enabled somehow.
    4. Something else?

    Type the name of the computer you want to access and then the user name as shown here: a\admin
    The example you showed above was only admin and the password. Computer "A" thinks the admin user from computer "B" is trying to connect. Hope this helps...

    Could it be this? (from Wikipedia)

    By default, Windows Vista and later use User Account Control (UAC) to enforce security. One of UAC features denies administrative rights to a user who access network shares on the local computer over a network, unless the accessing user is registered on a Windows domain or using the built in Administrator account. It is possible to disable UAC remote restrictions.
    You could add a LocalAccountTokenFilterPolicy DWORD in HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Policies\System and set it to 1.
