I'm getting this error in my testlab and in a production env.

This is probably conflicting with the existing NTP service on your system (probably W32Time). If you run the script without supplying a -p/--src-port flag it will pick a random source port, which should work in most cases.

If it doesn't (e.g. because a firewall blocks NTP traffic not originating from port 123) then you can try turning off the Windows Time Service before running the script.
