1. My server is named FS1. I can:
> ping \\fs1 and I will get a successful return.

the term "server" has so many meanings that it confuses me.
Do you mean a computer name which is set during computer intallation and
which is NETBios name?

2.I can:
> ping \\fs1 and I will get a successful return

I was wrong in my previous message.
If I ping using these two slashes before the name, I am getting "Unknown
host"

3.> Things that are important are:
> host name, primary DNS suffix, DNS suffix search list, connection-specific
DNS suffix,

In my case of workgroup peer-to-peer network are all these suffixes
relevant?

4. You use both \\computername\share and \\server\share and these seem to
have different meaning
In \\server\share - is it a literal, or I have to replace server with some
name? If so, where should I look for a name to use in place of server?

5. net use on Notebook
New connections will be remembered.

The command completed successfully.
The first line probably is due to the recent loss of a partition on Notebook
(it got corrupted and the drive became unavailable) which resulted in drive
letters change.
I do no know what Disconnected means. I still can access the drives marked
as disconnected.
Also all the network drives are shown marked with the red cross in
WindowsExplorer-->My computer, and sill I can access it. What does that
cross mean?
6. About these permissions.
The theory sounds good except one thing:
What is the point in these permissions as they can be bypassed by mapping
drives using IP addresses instead of computer names?
7. Security is a political thing. I would like to understand the technical
things first, then I will consider the security issues.
For the moment just one thing:
I do not care about people on my home LAN accessing each other files.
But I am concered about aliens from the Internet accessing my network.  The
security issues you mentiones - do the do with internal or external
security?
