How to Repair the Network in Windows

Lurking in various places around the numerous networking windows and dialog boxes are certain Repair links and buttons. Your first stab at resolving a network oddity is to grasp one of those Repair options to see whether using it helps. Here’s the rundown on where to look:

Network icon: Right-click the Network icon in the notification area and choose the command Troubleshoot Problems or Diagnose and Repair from the pop-up menu.

Network and Sharing Center window: In Windows 7 and Windows Vista, click the link Troubleshoot Problems or Diagnose and Repair. (These are essentially the same commands you can choose from the Network icon in the notification area.)

Local Area Connection Status dialog box: In Windows 7 or Vista, click the Diagnose button. In Windows XP, click the Support tab and then click the Repair button.

Network Connections window: Choose a network connection icon in the window, and then click the Diagnose button in Windows 7 or the Diagnose This Connection button on the toolbar in Windows Vista. In Windows XP, click the link on the left side of the window, Repair This Connection.

No matter how you get there, the results are the same: Windows looks at the network connection and attempts to resolve some issues. For example, it may renew an expired DHCP lease or it might explain that another computer on the network is “bogarting” your PC’s IP address.

If everything is okay, simply click the Close button and get on with your computer day.

There may be other locations where you can access the standard network troubleshooting utilities. Generally speaking, they all do the same thing described here.
