Hi David,
Thanks! I can now "ping" both computer with less that 1 ms ping response
time. I turned off the firewalls on both machines the "ping" response
time immediately went to almost nothing. I now have the firewalls
turned back on after doing some configuring to accept the network and
the response time is still less than 1 ms. I have enabled printer
sharing and that seems to be working properly.
I want to have computer number two to be able to share the modem and
dialup connection in computer one if that is possible. I know dialup is
slow but it is better than nothing. I live in a very rural area and DSL,
etc., is not available here. High speed satellite is available but is
cost prohibitive for me ($700 installation and $80 per month). Any help
setting that up would be greatly appreciated.
Thanks for the help from all of you,
Loy
