firewall problem...

Try this.

Start>run>"services.msc" (without quotes).
Scroll down to Windows Firewall/Internet connection sharing.
Right click and make sure it has started.
Also right click and go properties and under start up type make sure its on auto.

Thanks

EDIT: Then reboot.

Make sure that its startup is also set to ''AUTOMATIC''

Yes But Bolding it out. Thats one of the other important things he needs to do otherwise he will keep getting this issue.

Start>run>cmd

and type this without quotes:"Netsh winsock reset"

Go into the Service's again and go to the Firewall Internet Connection sharing and turn it onw using the steps above.

"Windows Management Instrumentation" needs to be turned on.

The windows firewall isn't actually all that bad...but all it takes is a few disabled services and some dependancies being turned off that is causing your problem.
