N E T W O R K BA S I C S

Ok. I'm a bit of a novice at networking but i'm fully conversant with my
computer.

i have a broadband modem running into a D link router and then 3 computers
connected via LAN cables ( i do not use the wireless aspect). there are four
lan sockets on the router. i have a pc upstairs and a laptop downstairs and
both can share folders and files on the network via the shared docs folders.
i have also enabled sharing on the root of a drive that contains all of my
music files.

the problem that i have is that the third computer is not visible to the
others and cannot be seen by the others. i have enabled drive sharing etc.

all three can access the internet. i want the third computer to be able to
share with the others.

how do i do it??

thanks..

Hmm, trying the simple stuff first. Are all computers part of the same
workgroup? Right click on "My Computer" on the desktop, and click on
properties. Click the Computer Name (tab) and check that all computers are
part of the same Workgroup.

Next on the computer that can't connect try right clicking on "My Network
Places" and click on properties. Right click on the network connection, and
then click on properties. Is File and Printer Sharing for Microsoft Networks
checked?

If this is checked, then most likely it is a firewall configuration problem.
Somewhere on the computer that will not connect their is a firewall blocking
the networking connection.

Steve -

David covered everything well but the one item you did not mention that left
me wondering about the third system... The system that can not be "seen" on
the network - can it browse out to a web page on the Internet? Another item
you might want to do is to check the TCP/IP settings. You can do this by
going to Start and then RUN and type in "CMD" without the " marks and then
press enter. You should have a black window open on your screen. Now type
in IPCONFIG /ALL
and you should see a lot of information but the only items to pay close
attention to are the

- IP Address
- SubNet Mask
- Gateway
- DNS

Write down the settings and then type "exit" and press enter which will
close the window. You need to do this on every PC you have. Then when you
compare the information everything should be the same with the exception of
the IP Address which must be unique for each PC. If the settings are not
the same (with exception of the IP Address) then all of the systems are not
on the same network.

i have all of this correctly but it still doesn't work.

my firewall is also configured to allow the other computers. i can see the
computer in windows explorer but it won't let me in saying that i don't have
permission, even though file and printer sharing is enabled.


is there a way in which i can delete all of my previous settings and start
again?

ok. i can ping the laptop which is 192.168.0.101 but i cannot ping the other
computer which is 192.168.0.104. it times out with 100% loss.

Steve,

I think this is your situtation but correct me where it's in error....

You have three systems on your network and the laptop is not able to play
nicely with the other two systems on the network. You checked your TCP/IP
settings using "IPCONFIG /ALL" on each system and found each system has a
unique IP Address and they all share the same Subnet Mask, Gateway, and DNS.
This puts you on the same network. You are able to sucessfully access the
Internet with the Laptop. You are unable to access the laptop files from
any other system on the same network. The key to the puzzle was supplied
when you figured out that you are not able to PING the laptop from the other
systems.

If this is all correct your issue is the Firewall on the laptop. You may
have installed a firewall on your laptop or you may be using the built-in
Microsoft NIC firewall that is a part of Windows XP. A firewall is 100%
necessary while the laptop is out roaming the Internet with wireless but that
same firewall is also going to stop your internal network systems from
accessing the laptop while it's on your LAN. So if it's a firewall you
installed then refer to the instructions that came with your firewall. If
you have the Microsoft Firewall enabled then it's a few seconds to disable
the firewall and try the PING and then access to the system. So if turning
off the firewall solves the issue then read up on the firewall with special
interest to the section about exceptions. The exceptions you can enable and
disable as you need either perminately or on the fly such as turning on the
exception when it's on the LAN and turning off the exception when it's on
wireless.

If this all works then raise a pint in thanks sometime.
