Problem with Internet Connection Sharing - Can't Access One Comput

I installed my network adapters easily and used ICS to link two computers.My
connections are enabled by a Linskys boadband router that I used to set up a
Vonage account.Clumsily and awkwardly I set up the link of the two home
computers. I was breezing along for a new computer user. I was successfully
placing files in the Shared Documents folders and exchanging folders between
computers.

My descent into disaster began when I tried to do a print job from a remote
computer. After several "error occured" messages I tried fumbling around with
the ports of a printer. This printer has a USB connector and I believe its
port is described as "virtual UsB port for printer". I'm not even sure now if
you can enable print sharing through a "virtual USB port". I continued to
foolishly persevere rather than seeking out technical advice. WELL,AN OPTION
CALLED PRINT POOLING WAS DISPLAYED AND I SELECTED IT. I chose five ports
with the logic that the print job would pick out an available , designated
port for printing.
INSTEAD DISASTER STRUCK. I got some vague message about a "break" in the
code of the registry(?) damaging the computer. Internet Explorer had to
automatically shut down citing an internal error had occurred.

Now my network access to the computer which I was attempting to do a remote
print job with has vanished, been liquidated. OUCH!!When I look under network
connection settings, the "friendly hand" that had earlier displayed is gone.
Further, I could not access this computer. When I executed the command
\\Computer Name\Shared Documents the "hourglass" locked up and then "path can
not be found" or similar was displayed. The drivers are listed as working. I
performed a Net Diagnostics Test: network adapters FAILED. This was my first
introduction to the Ping utility. I guess it sends out an address/path call
and expects an ech or respnse back. mY INTERNET CONNECTIONS FOR BOTH
COMPUTERS ARE FUNCTIONING.

I suspect I did some major damage to some programming code in the registry.I
will now probably just hook up the computers directly using parallel
connectors.

What you don't know can really hurt you in this game. Any help or insights
by competent computer users (that excludes me) would be greatly
appreciated.Please excuse the non-technical description of my problem. I
guess the print pooling in some way overloaded my network system.

Best of luck to everyone and may your computer be a source of pleasure and
education , not a tool of torure, confusion and agony.
