Connections disapp. from Conn.Folder

I have a notebook that had a lot of shortcuts for all my connections in the connections folder (Work domain via built-in network card, home workgroup & ADSL connection via built-in WLAN card, a large number of internet and work-domain connections via a variaty og analogue modems, ISDN-adapters and IR-Mobile phone modems).

Suddenly all connection shortcuts have disappeared from my connections folder. My work domain connection and the ADSL/home workgroup connections still work though – but the others (analogue, ISDN and IR-mobile modem connections are quite hard to start when the are no shortcuts.

I can define new connections through the connection wizards – but there are no new shortcuts that appear.

Can anyone help me ?
