Automatic Creation of Admin Shares

To re-enable automatic creation of the administrative shares, change the value of the following registry key to one (1), or delete the value:

For Server - HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\LanmanServer\Parameters \AutoShareServer

For Workstation - HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\LanmanServer\Parameters \AutoShareWks

A setting of zero (0) prevents the administrative shares, such as C$, D$, Admin$, and so on, from being created automatically.
