How do I Backup Dial-up settings in XP

I have a lot of Dial-up accounts set up in Windows XP but unlike Windows Me I can’t find a way of backing them up. and the ones I have backed up in Win Me can’t be used with Win XP.

Does anyone know how to overcome this apparent failing of XP, I’m sure there must be a way but I’ve been trying for hours now and I’m starting to pull my hair out (what’s left of it that is!)
