OK so our only problem at the moment is a network connection - correct

Go to Control Panel and select Internet Options
Select the Connections TAB
Select LAN settings button
Ensure there is no tick in the Proxy Server box
Select OK and restart Internet explorer

No check in Proxy Server Box…no connection

So the system is running OK

Seems to be, just can't get a connection for some reason

Are there other computers using the same modem with no problems ?

yes. I'm going to plug the cable running from this pc to theirs and see if still no connection.

No luck.

SO the cable does not work from the other computers This would indicate a cab;e problem

I connected the cable that was connected to this computer, so the cable is good. Still won't connect when I plug it to my parent's pc.

OK you may have a corrupted file lets see if we can find it

But first lets reset the netsh

For these commands click on Start…. Run….. type in…CMD ….press enter….to open a command prompt box

Reset WINSOCK entries to installation defaults…type in … netsh winsock reset catalog …. press …enter

Reset TCP/IP stack to installation defaults…type in…… netsh int ip reset reset.log … press …enter

If that should fail then try SFC

From the Start menu, select Run.
In the Open field, type sfc /scannow (Note: There is a space between sfc and /scannow)
Select the OK button.
Follow the prompts throughout the System File Checker process.
Reboot the computer when System File Checker completes.

Hello again. Okay, for CMD… after "netsh winsock reset catalog: I got this message: WARNING: could not obtain host information from machine: [YOUR-B27FB1C401]. Some commands may be available. The Specified service does not exist as an installed device. Successfully reset the winsock catalog. You must restart the machine to complete the reset. After "netsh int ip reset reset.log" I got this message: WARNING: could not obtain host information from machine: [YOUR-B27FB1C401]. Some commands may be available. The Specified service does not exist as an installed device. Should I try SFC?
