Anything that you don't specifically want. Allow your browser, your email
client, your news reader. Do NOT allow: Windows kernel, Windows Explorer,
RPCSS, DCOM, or any services running under Windows 2000 or XP unless they
are vital to maintaining Internet connectivity.
If you block something and immediately some feature becomes "broken," it's
very easy to go into the Applications dialog and allow it again.
