I did the fireware upgrade; which I appreciated you guys' info.
The upgrade did not solve the problem; but I finally have it resolved.
I needed to turn off two firewalls on my desktop -- the Windows' Internet
Connection Firewall and Norton Pernal Firewall -- before I could finally
ping thru from my laptop to my desktop.

I used to think that when Norton Personal Firewall was installed, it would
turn off Windows' firewall for me. I was wrong; it was not the case on my
XP Home SP1 desktop.

But turning off Norton Personal Firewall just to let my laptop to
access my destop's printer share -- it doesn't sound reasonable to me.
Maybe I should give up this idea.

Thanks for all you guys' help.
