Help! - DUN icons vanishing from Network Connections!

[Brian Gregory [UK]]

Yesterday my ADSL connection failed so I double clicked on one of a
number of dial up DUN connections I have had ready for this situation.
Immediately some of the other DUN icons vanished!
I immediately used Norton GoBack to go back a few minutes to get them back.
Then I double clicked another dial up DUN connection and more of less
the same thing happened again!! So I used GoBack again.

Does anyone have any idea what might be going on?
A virus or similar?

I'm running Windows XP Home with SP2 and all updates to date plus AVG
anti virus, Spybot S&D, Spyware Blaster and Ad Aware.

I think I've fixed this.

I think my Rasphone.pbk file had become corrupt or invalid.

I right clicked each dial up icon in turn selecting properties and then went
though some of the option flicking them on and on (or whatever) before
clicking OK.

The only thing I've done recently that might have caused the problem was to
rename and modify one of my calling cards I use to route through different
operators when using the dial up modem. I can think of no logical reason why
this should have caused the problem since the dialing location is just a
global setting and shouldn't effect Rasphone.pbk.
