Accessing Administrator Shares such as C$, IPC$ etc.. in windows server 2008 follows the same process as windows 2003 server operating system. When administrators or System engineers try to access admin shares eg: \\ip\c$ or \\FQDN\c$ or \\Netbios\c$ they will be presented with an error message “cannot access the share “ and would try to perform the following to access the admin shares.
- Turn off UAC
- Turn off Windows Firewall
- Restart the windows server and workstation services
- Check the service credentials
- Try to access with different administrator credentials
But unfortunately all the above method would still fail with the same /similar error message above.
The solution for accessing the administrator shares is to turn on the AutoShareServer registry key under
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\lanmanserver\parameters\AutoShareServer – set to 1
After you perform the above step, make sure you restart the server accordingly.
