• How do I configure my default Telnet client on Windows  for Smarts Network Configuration Manager (Smarts NCM)?

   1. Click Start Run.
   2. Type regedit
   3. Click OK.
2. In the Registry Editor, browse to the location: HKEY_CLASSES_ROOT\telnet\shell\open\command

5. Right-click on a device in the Smarts NCM client and select Cut-Through, and the Telnet client should now load.
