This feature has four modes of operation:

• 0 = disable RFC 1323 options
• 1 = window scale enabled only
• 2 = time stamps enabled only
• 3 = both options enabled

Create a new DWORD value named "Tcp1323Opts" and set it to equal 0, 1, 2 or 3 depending on the required mode listed above.

Restart Windows for the change to take effect.
