Two weeks ago my Internet went off and never connected again on my Acer 2920 laptop but it was still connected to every other computer in the house. I tried several WLANs but it keeps saying disconnected. I tried the Diagnose and Repair tool, but it says “network diagnostics can’t run because the diagnostics policy service is not running”. I tried running the service but it just said access denied error 5. Please help me?
Windows System Restore
One way to work around this error message is to use System Restore to set your computer back to previous settings before it encountered this problem. System Restore won’t delete any of your data, only change the configuration, however you will need to repeat any updates or any other changes you have made since the last Restore Point was saved.
How to Use System Restore
To use System Restore:
- Click Start, then choose Control Panel
- Type System Restore into the search bar and then Enter
- Under System, choose Restore System Files and Settings from a Restore Point
Access System Restore in Safe Mode
If this doesn’t work, you might see an error message about System Restore not completing properly. If so, you can try again, but this time access System Restore in Safe Mode. To boot your computer into Safe Mode:
- Power your computer down normally and let it rest for a minute
- Boot your system back up, wait a few seconds then start pressing F8 repeatedly
- If you get a keyboard error, power down and try again but wait a little longer to start pressing F8
- Choose Safe Mode using the arrows on your keyboard and press Enter
- Log in as usual
- Choose System Restore
- Choose a date before you noticed the problem
- Allow the process to run and reboot if necessary
Troubleshoot your IP Address
It’s also possible that there are system errors related to your Windows Firewall settings or your IP address. In some cases users need to edit their computer’s registries in order to resolve the error. Before we get to that, you should try the System Restore fix and, if it doesn’t work, try troubleshooting your IP address, you might need to contact your Internet Provider for help and details.
Update your Operating System
It might also be helpful to note that Microsoft is aware of this issue and includes a fix in the release notes for Service Packs 1 and 2 for XP. If you are running Vista, this might not apply to you, but it might not hurt to get all of the latest updates. Since you can’t connect to the Internet, you’ll need to use another computer and burn the updates to CD for installation on your laptop.
I hope this works, good luck!
