Thanks guys...God I love this pprune stuff...so useful..
Fobo - you lost me but I'm on RJ45's anyway. Thanks for the attempt.
DreamCatcher...I think you've nailed it. I remember doing that at the start and all worked perfectly...since then I've had the hard drive on one of the desktop machines completely wiped, reformatted and re-loaded - and the laptop that comes on line occassionally is a brand new toy that hasn't been purrrrsuaded into talking properly yet.
Bet that's it...I'll let you know.
