In the right-hand section, double-click on the NtlmMinClientSec DWORD (32-bit) Value to open its edit box. Now, if the Value data field of that box contains 20000000 (which is by default for 128-bit encryption), then replace it with 0 (for 40- or 56-bit encryption), and press the OK button to close the edit box.
