Default Computers Not Seeing One Another

I have networked (or tried to at least) 3 PC's - 2 Desk Top's and 1 Laptop.

Am using one PC to share the broadband internet connection which seems to work, but slows all the PC's down dramatically when doing so. All the PC's are running XP (Pro x 2 and 1 uses Home).

Now while the internet connection is able to be shared (albeit it at a very slow rate), the other PC's are not recognizing one another or reflecting on each's network place. All have been configured with XP's Network Wizard and all belong to the same work group, yet I still cannot get them to see one another or share files and printers etc.

What am I doing wrong and what do I do to fix it? Is there any way of preventing the PC's from slowing down when sharing the Broadband?

Have you checked the XP firewall on the two machines not running ICS?

most likely a firewall issue... check to see if you can ping each computer.. go to dos-prompt and type "ipconfig" to get the ip address for each computer then type "ping xxx.xxx.xxx.xxx" to see if you can get responses on each computer "you'll be pinging the other computers not the one your using".... if you can't ping them and your getting a request time out then the firewall are enabled and there blocking them from connecting to each other.

Thanx.

I have disabled the firewalls on all the PC's (will this not cause a problem when accessing the internet as it will leave all of them exposed to the rather large amounts of malicious software out there - on that note I do have Adaware and Spybot installed in the ICS PC).

The ICS PC is still not seeing the laptop and the upstairs PC, while the laptop cannot see the ICS and 2nd PC. The 2nd PC however can see the laptop, but not the ICS. Even though it can see the laptop it cannot access any shared documents or drives.

all the PC's are connected via a hub with flyleads if that may have anything to do with it.

I suggest using the Mozilla Firefox browser. This is the best measure you can do, browser wise. But I would also suggest using Zonealarm because that will block everything. Plus if you have money, check out Norton Internet Security Suite.

Athlone64fx, will advise when I have purchased the router.

Have tried Firefox in the past and whilst it has great security features, it seemed to be a lot slower to use than IE. (opening of the pages etc. Will give it another whirl though.

you don't need a router...
I'm willing to bet that the problem is puerly IP address based.
I would imagine your network connections are DHCP enabled (as that is standard) and I imagine that you don't have a DHCP server (as this is not really a sort of service you run in your home)...
so I'm guessing that when you type IP confog you got radically different numbers...
(when XP starts if it can't find a DCHP server it assigns an arbitary number that doesn not conform to private network numbering stabdards)

first advice... don't bother with any wizards.
disconnect the internet connection...

now go to all the PCs and do the following...

on the PC that will be connected to the internet

Right click on my network places and select properties.

right click on Local area connection and select properties,
select "Internet protocol (TCP/IP)"
and select properties.
click the radio button marked Use the following IP address...
in the IP address box enter 192.168.0.1
in the subnet mask box enter 255.255.255.0
leave the gateway blank...
Click OK
on the advanced tab of the LAN properties windows, turn off the firewall (XP will be skittish about doing this)

Now do the same on the PC
except set the IP address to 192.168.0.2
then do the same on the latptop except IP address is set to 192.168.0.3

for both the second PC and laptop set the gateway address to 192.168.0.1

check that all the machines can ping each other, and browse to any shared folders.
check that when you choose view entire network from the mynetwork places screen (and select windows network) that all the machines are in the same workgroup (or there will be file sharing problems.)

Now plug the internet connection back in...
BEFORE dialing the connection select properties for the internet connection.
on the advanced tab turn on the firewall, and check the box Allow others to copnnect through this connection.

Hopefully I'm right and have just saved you 30 - 80 in hardware that you don't actually need.

he has a broadband connection, so he dont dial up,

he would need an NAT client and windows xp dont have one pre-installed.

Hubs shoot packets out all ports becuase they dont know what IP addresses or MAC addresses are and it hs no sense or orginization. they are dumb devices now served mostly as repeaters.

since they dotn know what IP and MACs are they just aimlessly shoot all ports causing lots of collisions. one HUGE collision domain!!!

since switches have smaller ones and routers have very small ones.speed degradation does not happen.

he was complaining about his speed, and speed is king. routers arent very expensive.

broadband connection still dial, or at least still use a dialup manager to connect to the internet...
The point I was trying to make is that on my home network everything works fine...
It works for me, (without a router) and it should work for him/her too.
ICS in windows XP is usually more than adequate for connecting and serving the internet to clients on a home network.

the original post points to problems of file sharing and printer sharing as well, and what can I say at the end of the day I'm only trying to help.

I think you should truely exhaust all of the options before going outand buying new equipment, if the problem has nothing to do with routing and simply a network problem, then you advising that he wastes his/her money buying unecessary equipment that may not actually fi the problem.

the money you use to buy a router will pay for itself with management. lots easier and non-os dependant and IPs are managed easier. you can still use file sharing!!!!!

problemds with filesharing could result from the stupid hub!!!

it will fix it all he has to do is make sure IPs are in the same range and his workgroups are setup right.

now windows xp does not use dialup to manage broadband sicne broadband can not be dialup!!!

dialmeans phone!!! I dotn ahve a phone so i cant dial up.

its uses PPPoE and if its cable it doesnt use PPPoE!

Thank you both for taking the time to try and help. You have both been helpful.

On the broadband side, it is dial-up ( a product called iBurst { www.iburst.co.za if you interested} that can be connected by USB or Ethernet - requires username and password to access).

Root, will try what you recommended, but just as important is the subject of speed. My concern is that utilising ICS will slow my PC's down. If that is the case then the router (if it will speed connectivity up) will have to be the route to go.

First and foremost though is getting the PC's to see and share folders and files. The Broadband connection will be next.

it dotn reall "dial" its cslled PPPoE that requires authentication each time to make it more secure. It may seem liek its dialing, but no tone is heard and its just not constantly connected liek cable or other flavors of DSL are.

filesharing only requires IPs be setup correctly and workgroups setup properly,

such as, For example

wokgroup name: Kittykats

Default gateway:192.168.0.1
SubnetMask:255.255.255.0
DNS: use ones provided by ISP

PC1: IP: 192.168.0.101 name: Angel
PC2: IP: 192.168.0.111 name: Frisky

now to go setup workgroups:

right click on my computer,
go to "computer name" tab
then click change
under workgroup you should have it setup as:KittyKats

click, ok, then ok again and it will give you a welcome message or soemthing like that.

then thats should be it! a restart may be needed if they dotn see eachother right away.

PPPoE has a connection socket rather than dial becuase its not using a COM port.

try subnet 255.255.255.252 its safer against hackers .especially on infrared.

or use subnet calculator wich u can find on google.

I dotn think he'd need to mess with subnet masking.

IP and workgroups have always worked for me as long as the physical media didnt have any problems.

your rite he shouldnt mess with it if the subnet is the same(if he checked that).but else it would never work i guess.if u have a router it will usually give u a class c subnet when u have ip dynamic.but when u set it static my router for example give it a class a 255.0.0.0 subnet wich btw enables u to connect about sixteen million comps(wich is not a good thing) the subnet has to be the same and the best would be a range that actually allows u to only connect the comps u need.

subnet 255.255.255.252 would be 4 host adresses.

u could try a subnet calc and play around with it
