Network Programming in .NET

Recently, I was asked to fix a Windows XP laptop where the internet connection was not working on either WiFi or wired connections. After checking device manager, I spotted yellow triangles on lots of Network Adapters. On clicking on these, I saw the message “Windows cannot start this hardware device because its configuration information (in the registry) is incomplete or damaged (code 19) ”

Then I noticed a pattern, all the failed network adapters were marked AVG miniport driver. So, my initial reaction was to uninstall AVG and reboot, but that didn’t h help. I couldn’t remove the failed network adapters either, so I checked the web, and found this procedure:

Windows Vista, Windows 7:
1. Open menu Start -> (Settings) -> Control Panel.
2. Double-click Network and Internet -> Network and Sharing Center.
3. In the left pane, click Change adapter settings.
4. Right-click the connection you are using and select Properties.
5. Under This connection uses the following items un-tick (clear) AVG network filter driver.
6. Click OK to store the changes.

Windows XP:
1. Open menu Start -> (Settings) -> Control Panel.
2. Double-click Network connections.
3. Right-click the connection you are using and select Properties.
4. Under This connection uses the following items un-tick (clear) AVG network filter driver.
5. Click OK to store the changes.

Which worked for me!
