If you have a firewall disable it to see if that helps. If it does help, we need to find out how to open the firewall to the local network. Don't run without the firewall though. If you don't have a firewall, get one once this is fixed.

Make sure that the new PC is using DHCP. It's possible that you need to do start | run |

type cmd

hit enter

type ipconfig /release
type ipconfig /renew

type exit

This would renew the IP using DHCP.

that's all that comes to mind to start with.

[I.M.O.G.]

Right click on my network places and select properties - or go to control panel and open network connections and right click on your LAN connection and select properties.

Then select TCP/IP and select properties. Check to make sure its set to automatic for IP and DNS. Then select advanced and under IP address insure DHCP enabled is listed.

You will then need to log into the router, typically done by entering 192.168.1.1 or 192.168.2.1 into the address bar of your internet browser. Try this from both machines, and see if you can access the router from both machines. If there is a password to access the router and you do not know it, you can look up what the default is for your router in google.

Once you are into the router settings by following the above instructions, you will need to ensure DHCP is enabled on the router also.

You can also find instructions online for this specific to your router - you should let us know what the model number is of your router, and then we can assist you more accurately. This should be listed on a sticker on the router.

I agree w/ I.M.O.G and add something more..
Besides going to network connection - TCP/IP
to see if both ip address and DNS server are set to automatic,
you might go to your web browser(assume you use IE),
go to tools - internet properties - connections,
then go to "LAN settings". Make sure you uncheck the proxy server
if you dont use proxy server at your home network.

Try our methods first to see what's going on,
if there's still a problem, we can discuss later on.
Hope it works.

Nice input gluo, and welcome to the forums! :)

I'm anxious to see if any of this helps the OP solve his problem, and expect it will.

i disabled norton internet security and it works now. Thanks!!
But how do i find out how to open the firewall to the local network?
Thanks

You will need to NIS and add the range of IP's for your LAN to the trusted group.

Select personal firewall, click on configure, select networking, select trusted, then select add or wizard.

Let me know if you need further instruction and I can give it a shot. To know what range to use, you could log into your router like I mentioned earlier, and find the DHCP settings to see what range it uses, then use the same settings in NIS.

theres not networking option in NIS. Only firewall and theres a http port thing list and a few other options. i found out my ip by logging into the router and looking at the DHCP table. Theres two connections on there (2 computers) they have the MAC and IP address next to them.

[I.M.O.G.]

If you click on firewall, you will have an option to configure - those were the directions above. After you click on configure, a window will pop up, and there should be a networking tab which you can select. ;)

What version of NIS are you running, as I could also be wrong in my instructions... but I think you might be looking in the wrong place, not sure.

What is the model of your router? It would be best to enter the range of values that DHCP may assign into the trusted field - by nature DHCP assigns IP's dynamically. So if you only enter the current IP's, and one of their values change, then your network will be broken again.

For example, your router may assign internal IP's from 2-40, and then you would need to tell your firewall to trust that range of IP's.

it working fine, I had clicked the wrong thing, i followed your steps and it works fine.
Thanks for all the help

[I.M.O.G.]

Awesome, glad its working for you. :D Keep in mind what I mentioned about using the range for IP's - you can do it either way and it will work great for you now. But if you do not use a range, down the road you might have a problem like this again.
