Kass,
Improperly configured, and otherwise malfunctioning, firewalls can cause
problems in many different ways. I've seen so many different symptoms resolved
by un installing firewalls.
In some cases, you have to totally un install related software from the
manufacturer. In one case, Norton Personal Firewall (part of Norton Internet
Security) was malfunctioning, and we couldn't get file sharing working until
Norton AntiVirus was also un installed.
The "...access denied..." error can be caused by several different problems.
The browser (on the LAN) provides the display of shares that you see. When you
try to access one of those shares, the computer name in the share has to be
resolved to an address. There could be no problem with the browser (one
component of file sharing), but name resolution (another component) could be
broken, causing the error.
Let's try something else. Just as you did "\\Main" then "\\Randall" from both
computers, do "\\192.168.0.1" then "192.168.0.235". Let's see what happens when
we bypass name resolution.
When I suggested that you "Try mapping a share on Main, from Main. Can you open
a file, From the Share setup on itself?" I was having you treat Main as a server
for itself.
With file sharing, you have a Server (running File and Printer Sharing for
Microsoft Networks (FPSMN), aka lanmanserver) and a Client (running Client for
Microsoft Networks (CMN), aka lanmanworkstation). If either one of those
services is broken, file sharing won't work.
If Main (as a client) can access Randall (server), then you know that both CMN
on Main, and FPSMN on Randal, are operational. If Randal (client) can't access
Main (server), then either CMN on Randal, or FPSMN on Main could be broken. How
do you tell which one is broken?
The best way is to test Main from itself. You know CMN on Main works (other
test), so if you test Mains ability to share with itself, you are only testing
FPSMN on Main.
So I tell you to setup a share on Main, then try and reference that share from
Main. And see what happens.
Your question about security from a router does not have an easy answer. A NAT
router (which is what you buy at Best Buy) provides good protection against
incoming hostile traffic. But it's only ONE ESSENTIAL component in a layered
protection strategy, which is what you absolutely need today.
If you could see your way to using a router (the cost is absolutely worth it!),
we'd both be better off. Is your dialup service PPP compatible?
I'll discuss security in detail after this is over.
Cheers,
Chuck
Paranoia comes from experience - and is not necessarily a bad thing.
