To do this fix you would need to be on the server ( as you may lose internet access).
First, turn Hamachi on ( you'll lose internet access)
Go to the Hamachi network adapter and right click select properties.
Choose Internet Protocol Version 4 > Properties > Advanced
Uncheck Automatic Metric and then set it to 9000.
What I then like to do is go to your other network adapter and set that metric to a low metric like 10.
