Chuck,

OK, I'd done a ping from cmd but did this from Start:Run as well. From
Main, I did Start:Run \\192.168.0.1... I can see and access shared files,
including the shared My Documents on Main. I can Start:Run \\192.168.0.235
from Main and see and access shared files on Randal. On Randal, I can see
and access Randal files, but from Randal, if I go Start:Run \\192.168.0.1 I
get the "access denied" message.

If I understand correctly (I think this is making my brain go to jelly) on
the mapping, this is what I did. On Main, I shared My Documents... then from
Main I accessed through My Network Places, Main and opened that shared
Document. Is that correct? In otherwords, I'm using Main as the Client to
access files on Main as the Server and yes, I can access Main and it's shared
resources. Dude, you are going to make a geek out of me! My family thinks
I've slipped off the edge when I start talking about this stuff. I think my
kids are ready to stuff me in a closet! :-)

Tomorrow when I go in to work, I'm going to try disabling Norton and see if
that helps.

You read my mind on the router thing. My home network is a piece of cake...
Lynksys Wireless B (Model BEFW11S4), has both wireless and ethernet
capabilities. I have 2 desktops on a LAN and a laptop on wireless. After
installing XP SP2, I had to do some reconfiguring to get everyone to see and
acknowledge everything, but nothing like this stupid ICS for a dial up. If I
were anyone out there using a router, I wouldn't touch ICS with 100' pole!
Keep it simple!

Can you get a router that will work with dial up? I looked a bit, and
pickins look slim to none, but perhaps I wasn't searching properly. If this
keeps up, my boss may decide to fork out for DSL rather than watch me have a
nervous breakdown (or have to listen to me talking Geek! :-) We used to try
to FAX through software on the computer and I convinced him this is the same
senario.... software just doesn't cut it compared to a piece of hardward made
to do the job.

Have a good week-end (or do you live a Help and Support? :-) If you work
for Microsoft, tell them to just make a simple program where to get into a
computer and use it's resources, you have to log in with a user name and
passwork like getting on a server to do web work and forget all this ICS
Firewall @!%$.

Thanks, Dude!
