Cann't connect Admin Share member of administrators group

\\servername\c$

Can connect to it using the default Administrator account. But if I try to connect using  account that is a member of the Administrators group,  can't.

create the LocalAccountTokenFilterPolicy DWORD value at this key in the registry

HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Policies\system\

0 - build filtered token (Remote UAC enabled) 

1 - build elevated token (Remote UAC disabled)

or you can add this key from CMD :

reg add HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Policies\system /v LocalAccountTokenFilterPolicy /t REG_DWORD /d 1 /f
