new at vnc, timed out connection

[Charles Larke, Jr.]

Dear Sirs,
This is my first experience with vnc.  I am using WinXP Pro. I just installed
the latest personal trial version of realVNC. I cannot get the program to
connect to any ip of any server before timing out even though I can
successfully ping to the same addresses.  I allowed remote control in system.
I use DSL from earthlink. Can anybody help me get connected?
Sincerely,
Charles R. Larke, Jr.
