Windows 10 can only access administrative shares on server 2019 machine with the default "Administrator" account

[PatrickSteiner]

Hello,

I have a server 2019 machine isolated in a DMZ. It is not part of a domain.

I am able to access the administrative share for c$ and f$ on the machine when I log in with the "machinename\administrator" account and password.

I created a new administrator account on the server and put it in the administrators group only.

I can remote desktop to this machine using the newly created account name, but I cannot access the administrative shares using this account. I'm using the local machine name as the domain and am sure the username and password are correct.

What must I do to grant administrative share access to this new account?

thank you

Patrick
