By default, UAC remotely restricts these shares from being accessed. In order to successfully connect to an administrative share, you’ll need to disable this feature. To do this, you’ll need to create (or modify) a registry DWORD value called LocalAccountTokenFilterPolicy and set it to a value of 1.

Follow the Steps:

Step 1: Open the registry from run command to type regedit

Step 2: Go this registry path:

HKEY_LOCAL_MACHINE\ SOFTWARE\ Microsoft\ Windows\ CurrentVersion\ Policies\ System\

Now create the new DWORD 32-bit Registry entry with name: LocalAccountTokenFilterPolicy and give value 1
