Computer Networking - December 2007

This problem has me really got me pulling my hair out.
My network consists of 16 clients and 1 server, all running Xp Pro. I have them divided into three groups all connected together using three 8 port switches, with one switch getting the internet connection from a D-Link router. I have been using this setup for years without any problem, but my 8 port switches are getting old.

So, i decided to purchase a 24port Edimax switch. Since i want to test it out before doing any major UTP rewiring, i connected the group closest to the router, directly to the 24 port switch (removing their 8 port switch out of the network). then i connected the two other 8 port switches to two ports on the 24 port switch.
i run a ping test on yahoo.com (ping yahoo.com -t) on all the clients and everything seems to be working fine. after a few minutes, one or more will timeout for quite awhile while maintaining local connectivity. i changed to Cnet 24 port, same problem. if i bring back my 8 port, no prob

As data packets are moved from one network hardware device to another over a network, hardware address (MAC adresses) come into play? So how a hardware device disovers the MAC addrss of another in the event that it is unknown.

All of my computers have Window XP SP2, and have remote access assistant on them. I want to be able to connect them to each other, but they all have the same IP! And if I want to connect from an outside computer, what IP do I enter in to reach a specific computer within my home? I know I can use places like logmein.com but some places with outside networks will block certain sites and that might be one.

I am having issues with my internet not working properly. I want to try to plug my cable internet into my computer or laptop, without using my router to see if it is an internet connection problem or a router problem; because I do not want to buy another router. Since they are so expensive. Please advise.

I got an Xbox 360 recently, and my dad is constantly online, and I am really annoyed. I plan to buy a router, I can buy one as long as it is in the 50-60 dollar area. There are some specific requirements though - Those are listed right here:

-Must be compatible with Windows Vista
-Must be compatible with Xbox Live
-Must have a good stable connection with my DSL modem

Okay, so I have a job to finish, and I just can't figure out DNS, can't wrap my head around it.

Here's the situation using fictitious PUBLIC routable IP addreses.

Say I have a domain, say it's lizdomain.com
Say I have that registered with godaddy.
Say I want to host it myself on an Ubuntu 7.10 gutsy server. Say I also want that same server to do the DNS, and be the mailserver for this zone:
I know I need the following.
A zone configuration file
an SOA (???!)
proper configuration of a file called named.conf in /etc/bind/ (jailed elsewhere, but that's all working)
a reverse DNS i think ptr file.
other stuff.

So what I'd like to know is.
what files to I need to edit, where do I find them, and what should they look like, how do they talk to the other DNS servers in the world, and basically what would a proper bind9 setup look like for:

lizdomain.com
web server public IP: 99.1.1.99
DNS server same (use loopback here?)
mail server same
machine's hostname is lizserver1

Dear All,

We are having two offices and each office has seperate internal networks of windows XP computers operating as WORKGROUP, with each computer in both the networks having addresses such as 192.168.x.x

The networks are connected to internet by means of a DSL connection.

Now, we want to share a folder in one of the computers (say 192.168.0.5) in branch 'A' so that persons in branch 'B' are also able to read/write.

Both the offices are small and around 10 computers in each office.

Now my question is,

a) what changes in configurations are to be done for sharing for the above purpose.
b)Is 'VPN over internet' option in XP can be relied for security for office networks.
c)If not, what other options are available, and how to configure the systems.

I will surely vote for best answers..

thanks/regards,

There are a times when the server status apperas busy and the LAN Monitoring tools indicates a lot of LAN activity.
Does anyone know where I can download software to monitor the following;
1. Users and Computers connected, their names and IP addresses.
2. The activity on the LAN i.e users activity maybe they are copyiong or reading from the server.
3. The LAN statistics i.e the most active users and computers.
4. The software giving the option of net sending to computers/users on the LAN and remote shut down a client computer.
