Unable to connect to internet; diagnostic policy service not running?

[etierney]

Hey everyone, if anyone could provide any information on this issue, i'd greatly appreciate it. My mom's laptop is detecting that our wireless internet connection is active, but it won't actually connect to the internet. When we troubleshoot the issue, it says that our diagnostic policy service isn't running. Since we can't connect to the internet on the laptop, we can't run any updates or perform any virus scans. We've tried manually adding a network service through cmd.exe, and uninstalling the network adapters and restarting the computer. We've also tried to run a system file check, but it doesn't seem to activate. The sfc box just disappears when we try to initiate a scan. I imagine we might have to back up her important files and just reinstall the operating system, but her laptop came with a preinstalled OS, and no discs. We'd be very thankful for any info or suggestions.

See if you are connected to a 'proxy server'

1) Under “Tools” in the browser tool bar select “Internet Options”.
2) In the “Internet Options” window that pops up, click the “Connections” tab at the top.
3) Click “LAN Settings” near the bottom of the “Connections” section.
4) If the “Proxy server” checkbox is marked with a check, click it to deselect/uncheck it.
5) Click “Ok” to close the “Local Area Network (LAN) Settings” window.
6) Click “Ok” to close the “Internet Options” window.
Reboot
Make sure "Proxy server" is still disabled under your LAN Settings.
Test whether internet connectivity is restored.
