Win XP Pro network down after upgrade from W2K

I upgraded two computers from W2K to XP Pro today and in the process lost the network between the two computers. They're connected through a hub that also allows cable internet connection using two different IP addresses.

I can't ping either computer but do have internet connection.

When pinging the other computer I get the error message: Workgroup not accessible, you may not have permission etc. etc.

Since the network went south after the upgrade, it seems to me that it is a software and not a hardware problem.

Any idea what to do???

Thanks

Ray

Check that both computers are on the same workgroup and have different names set. Check that IP addresses are set correctly so that they are on the same subnet. For example, make sure that all computers have an address like 192.168.0.x, the subnet mask set to 255.255.255.0 and the default gateway set to the IP address of the router/computer with the Internet connection. Also check that firewall software isn't installed or is disabled. You also need to disable the built-in Windows XP Internet Connection Firewall on the local network connection.

They are in the same workgroup with different names

Where do I check that?

Where do I set these settings?

Also check that firewall software isn't installed or is disabled. You also need to disable the built-in Windows XP Internet Connection Firewall on the local network connection
No firewall and XP-firewall is disabled

Thanks for your help!

hey Ray Fluitsma to check the ip go to network connections under control panel and right click on the local area connection click internet protocol TCP/Ip so that it's highlighted and click properties, this is where the stuff edwinbrains was talking about make sure that these are set and that they have ips like 192.168.0.XX the last number can be anything you want but different for every computer. and also make sure the subnet mask is set, just click on it and it will automatically but 255.255.ect in there for you. To disable XPs firewall go back to the local are connection properties and click advanced and uncheck where it says protect my computer and network...etxc and that should work, hope that helps.

in the process.

Right clicked on network connectios and set the IP to 192.168.0.1 the subnet mask to 255.255.255.0 and the default gateway to the ip addy shown by ipconfig.

all that resulted in a loss of the internet connection......

HEEEEEEEEEEEEEEEEEEELP!

Ray

To get it back just delete those settings.

Can I check the settings you've currently got configured. Click Start, Run and type "ipconfig /all > C:\ipconfig.txt" (without the quotes). A black screen will flash up. When this closes, find the file ipconfig.txt in the C drive and copy the contents into your next post. Also do this for the second computer.

ipconfig /all > C:\ipconfig.txt and guess what, it is not on my computer. Did a search for ipconfig.txt and came up with nothing.

Any suggestions or do I need to call Bill and ask him??

I appreciate you help ........

Ray

You should definitely have it there

Click Start, Run and type cmd. A black Command Prompt window should open. Then type "ipconfig /all" (without the quotes) and you should get some information about your computer's network connections. If this is ok, then type "ipconfig /all > C:\ipconfig.txt" (again, without the quotes). When it has finished, there should be a file called ipconfig.txt in the root of your C drive. You're using XP so this should definitely be there.

I type in ipconfig/all and a dos box appears for about 1 second after zome alarm asks if it ok for that program to access the internet. Permissin is given and than the box disappears.

So what do I do in order to make this window appear longer?

Ray, still optimistic about things........

If you're typing this straight into the Run dialog box, the black Command Prompt should disappear after about 1 second. Then, open Windows Explorer, browse to the C drive, and there should be a file called ipconfig.txt directly in the root drive (not in any subfolders).

and run ipconfig/all>c:\ipconfig.txt from the dos prompt to get the info.

Still optimistic

Ray

I'm confused why you have internet Ip addresses within your local network. Within a local network, I would use addresses like 192.168.0.x or 10.0.0.x. Then get your router to have two interfaces, an internal one and an external one, and then enable NAT so it appears that all requests come from the one external IP address.

to explain to me what exactly it is you want me to do?

I'm not familiar with the term NAT. All I did was changing the operating system and ran the network wizzard and before I knew it, you're trying to help me out.

I'm still confused but am optimistic and willing to folllow instruction to a T

Ray

see the other computer from my computer but cannot access it. When thrying to access it tells me that I have no permission and that the administrator needs to be contacted. Since that is me I gave me permission but that failed to impress the other computer. Hard drives and so are shared.

HEEEEEEEEEEEEEEELPpp


Ray still optimistic but confused....
