Thanks
fobotcso for your suggestion.............
After much diagnosis I discovered the process 'Rnaapp' was the culprit responsible.
This process loads with windows, and is the 'Microsoft Dial Up Networking' program. It has a known problem in that it sometimes fails to shutdown, and on restart won't allow another connection because it thinks it already has one. Hence the error650 !
I've downloaded an Alcatel SpeedTouch support driver fix, which seems to be working !!
Many thanks, this has been driving me nuts for months
Moley.
