SUMMARY

This article describes troubleshooting methods that you can use to resolve missing Network and Dial-up Connections icons. The following issues may occur if you click Start, point to Settings, and then double-click Network and Dial-up Connections or if you right-click My Network Places on the desktop and then click Properties.

The Local Area Connection icon is missing.
The dial-up connection icons are missing.
The Make New Connection wizard icon is missing.
Only the Make New Connection icon appears, or one or more dial-up connections also appear.
If you click the Advanced menu, and then click Advanced Settings, only the [Remote Access connections] entry appears in the Connections pane.
The Network and Dial-up Connections Explorer quits responding (hangs) after you select a network connection and then click Properties.

Notwithstanding these issues, networking continues to function correctly, and the Ipconfig command still shows all connection and adapter information.
