When you try to right click a network connection in the Network Connections folder in Windows XP and select Properties, you get an error message that says "an unexpected error occurred". Not very descriptive, so what is the problem?  The most common cause of this problem is damaged registry settings that prevent you from viewing the network connection’s properties.

To repair this problem:

1. Click Start | Run
2. In the Open box, type: regsvr32 %systemroot% \system32 \ netshell.dll
3. Click OK in the dialog box.

If the problem persists then do the following:

1. Repeat step 1 above.
2. In the Open box, type: regsvr32 %systemroot% \ system32 \ ole32.dll
3. Click OK in the dialog box.
4. Reboot the computer.
