"You may receive some alerts asking you if a certain program should act as a server and be given "server rights". We recommend that you not give any program server rights unless one of the following is true for you:
You are hosting a Web site on your computer
You are sharing files with another person(s)
You are playing games that require point-to-point connections with other players across the Internet
If any of these situations apply to you, then you should give programs for the activity server rights. If none of the above examples applies to you, it is not recommended that you allow any program to have server rights. Allowing a program to have server rights means that an outside connection can access your computer through that program"
