Page 2 - Win XP Pro network down after upgrade from W2K

Right, how do you connect to the Internet? I would have thought that you would have something like a router, which plugs into both your local network and the Internet. Since this has two connections, one will be a public external one (like 65.35.177.234) and one will be a private internal one (like 192.168.0.1). You should be able to setup your router to share the Internet connection and enable NAT. What this means is that when local computers on your network (with IP addresses like 192.168.0.x) try to browse the Internet, your router changes the individual packets so that it appears that all requests come from the external address of the router, rather than the internal computers.

What this means is that computers in your local network want addresses like 192.168.0.x and the router needs two IP addresses - one external and one internal.

For the permissions issue, try making sure that you are using both computers with accounts which have exactly the same username and password. I presume that if you've got this far that you can now ping the other computer?

cable modem. The cable modem lead goes to the router. From there two leads go to the computer, one to each, of course.

Funny thing is that today my computer sees only itself and so does the other one.

So how do I setup a local network in both systems? Where do I key in the settings? Do I use Networks Connections/TCP IP Properties/General or do I use Alternate Configuration?

Where do I set the Private Internal network parameters?

What is NAT?

I am a bit confused by what you wrote. I have two computers that need to go in a network. Do both computers need to have exactly the same username and password? And again, where do I set these? Both computers have no username or password that need to filled out when booting up.

Thanks for you patiende and help!

Ray, still confused but optimistic

PS. I write security programs for a living...this is way more complicated I think.,......

We'll get there eventually

Firstly, you're using a router which is good. This should have an IP address of something like 192.168.0.1, or 192.168.1.1 or 10.0.0.1. It'll be something like on of those, you should check in the manual for the exact address. Once you've found out what the IP address is of the router, you need to configure your two computers.

Open up the Control Panel and click Network Connections. Right-click the Local Area Connection and select Properties. Double click Internet Protocol TCP/IP. In this window, select "Use the following IP address", and enter an IP address in the same subnet as the router. For example, if the router has an address of 192.168.0.1, enter something like 192.168.0.10. Set the subnet mask to 255.255.255.0, the default gateway and the DNS server to the IP address of the router. Click OK and repeat the process on the second computer, making sure that you use a differnet IP address.

This will probably get you setup OK. If it doesn't, check the router config. Browse to the IP address of the router to access its web based admin pages. Make sure that the Internet is setup properly, and that NAT is enabled.

To try and explain more clearly, NAT is network address translation. When you browse the Internet, your computer will have an address liek 192.168.0.10. This is an internal IP address only. NAT turns this IP address into an external public IP address.

The permissions thing shouldn't be a problem. However, if you are getting a permissions issue, it's worth making sure that on both computers you're using an account with exactly the same username and password. You probably won't need to do this, but it's worth trying if it doesn't work. To set a password, open up the Control Panel, and click User Accounts. Select your user account and look for the option to create a password.

I like the way you keep saying "still confused but optimistic"! Hopefully you won't be confused for too much longer!

I have a netgear router and the instructions have no reference to IP addresses for it. So I called netgear only to be laughed at since their hubs do not use IP addresses according to the unfriendly person I talked to.

So...I ran IPCONFIG/ALL and typed in that info in the IP PROPERTIES box and this is what I have now:

My Computer:

Now here is what happend:

Computer 1(Ray) allows me to see computer2(Annie) but not access it, get the message about permission and so on.

Computer 2(annie) tells me the MSHOME network is not admissable....

WAAAAAAAAAAAAAAAAAAAAAAAAAHHHHHHHHHHHHHHHHHHH


Ray still confused but remain optimistic.....

I'm slightly confused as well at the moment:



A hub is very different from a router. I really need to know exactly which one you use before continuing. A hub just connects lots of computers together. A router does this, but also has the capability to share the Internet connection.

I have a Netgear hub DS108.

Cable modem goes to hub and the leads from both computers go also to that hub.

I erased the word router from my memory for the time being...

Ray Still confused, manged to confuse Edwin, but am still optimistic

lmao

I think you'd be better with a different network setup. Get one of the computers a second NIC. Unplug the cable modem from the hub and plug it into the new NIC on the computer Setup this computer with the Internet connection and then setup sharing. Have a cable from the second NIC plugged into the hub, where the second computer also has a cable. This way, you'll have a internal local network between the two computers, and one of the computer will share the Internet connection to the other. I think this would work

I can cancel the second IP address that I have. I have it so that both computers do not have to share an internet IP addy.

Will this new setup slow net access down?

Ray, even more confused but like new approaches now and then

It'll be coming clearer soon

Yep - you only need the one IP address. The first computer will have two IP addresses - an external one and an internal one. The external one will be the one provided by your ISP, the internal one will probably be 192.168.0.1. The second computer will only need the IP address 192.168.0.2 (no Internet IP address).

The Internet will not be slowed down by this - you won't notice any differences.

but do not have any spare cable laying around to make the connection. Good thing this is the US, ready to accept your $$$ any time of day.

I'll be back on this topic....


Ray, moderately confused and the way to buy cable.....

I'm glad you're getting less confused

Just see how you get on when you get the cable and post back if you have any problems or questions.

what?

Configuration now is:

Computer Ray 2 nics, one for the internet and one for the internal network.

Computer Annie, one nic for acces to computer Ray and through computer Ray, to the internet.

IN that configuration I have no internet on either computer nor do I have a network.

Sooooooooo....cable from computer Annie directly to cable modem results in an internet connection.

Cable from computer Ray directly to cable modem results in an internet connection.

Now what to do????????????

WAAAAAAAAAAAAAAAAAAAAAAHHHHHHHHHHHHHHHHHHHHHHH

Ray still a little optimistic but totally confused now......

OK - you've got the basic setup correct

On the Ray computer, you need to plug the cable modem into one of the NICs. Check that this is setup correctly. You'll need to use the external IP addresses you used before:
IP Address. . . . . . . . . . . . : 65.35.177.234
Subnet Mask . . . . . . . . . . . : 255.255.248.0
Default Gateway . . . . . . . . . : 65.35.176.1
DNS Servers . . . . . . . . . . . : 65.32.2.136
65.32.2.147

When you've set these settings on that NIC the Internet should work on that computer. You then want to configure the second NIC. Set the IP address to 192.168.0.1, the subnet mask to 255.255.255.0, and leave the default gateway blank. Set the DNS servers to 65.32.2.136 and 65.32.2.147.

Then, setup your second PC. Set the IP address of the only NIC in the other computer to 192.168.0.2. Set the subnet mask to 255.255.255.0 and the default gateway to 192.168.0.1. Again, set the DNS servers to 65.32.2.136 and 65.32.2.147.

After you've done this, you should be able to do what you want. Check that you can ping from one computer to another and then check if you can access the Internet.
