4.12. Error: An attempt was made to access a socket in a way forbidden by its access permissions.

Q:  When I try to start the Multi-User Server I get an error that says:  "An attempt was made to access a socket in a way forbidden by its access permissions.  I can't start the Multi-User Server, how can I fix this?

A:  This is the result of too many incomplete outbound TCP connection attempts.  If a program tries to connect too many times to an IP address which is not valid then Windows will start to impose limits on the number of these connection attempts.  Here is an article from the Microsoft Knowledge Base which explains the issue in greater detail, and also provides a solution.

An easier solution is to reboot the EstiMate Multi-User Server computer/server.  Once the computer/server is back up launch the Multi-User Server, and it should start right up, and you should be able to connect to it from EstiMate.
