By default, Windows automatically creates an ADMIN$ share, a resource that is used during remote administration of a computer. If this share is not accessible, N-central will be unable to install software on client machines that is required by remote agent installation, remote management tasks, or remote control tasks.

The share folder should be accessible by browsing to \\<hostip>\admin$

If the share is not accessible, please check the following on the target device:

File and Printer sharing

File and Printer Sharing must be enabled in order for the share to be accessible.

  1. Open Control Panel from the Start Menu or Windows desktop.
  2. On Windows XP or Windows 2000, open the "Network Connections" Control Panel applet.
  3. On Windows XP or Windows 2000, choose the connection to enable / disable sharing.
  4. View the properties for this connection by right-clicking on the icon and choosing "Properties" from the menu. If the connection is a dial-up connection, click the Networking tab to view its properties.

  5. On Windows XP or Windows 2000, ensure the "File and Printer Sharing for Microsoft Windows" checkbox is checked to enable sharing
  6. Close the open properties / Network windows and Control Panel.


In the 'Exceptions' tab of Windows Firewall property, the 'File and printer sharing' should be allowed.


There is a registry key that controls the administrative share access.

For NT4 Servers, Win2K Servers, and Windows Server 2003, go to:

  • HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\LanManServer\Parameters
  • Name: AutoShareServer
  • Data Type: REG_DWORD

For NT4 Workstations, Win2K Professional, XP Professional, go to:

  • HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\LanManServer\Parameters
  • Name: AutoShareWks
  • Data Type: REG_DWORD

By default, the above registry entries should be absent. If the entries exist and the value is 0, then the shares have been disabled.
