Can you help me get a list of the ports used by applications such as ICQ, Real player and all other internet applications.

And how opening up of these ports can risk the security of an intranet in a company?

Start with your computer and open Services file (no extension) in your Windows directory, eg. C:/Windows/Services

A bit more you can find in NT Server Resource Kit (Networking Guide - Appendix B)

Still more, search Internet for RFC (Request For Comments), Services file refers to RFC 1060, but I believe that standard has been updated since.

Hope it helps.

Sorry, missed second portion of your question. Concerned about security? obviously your intranet is already connected to the Internet and likely you have some sort of protection implemented. It shouldn't greatly increase the risk if done properly.
