I've tested again and it seems to happen on any track. Usually it cannot survive more than one song in a playlist, but sometimes it staggers into a 2nd before conking out. I tried googling the error code, but am not smart enough to get any further. I am intending to reinstall Windows on the server box anyway, so don't worry yourself unduly. If it ocurrs post rebuild then I will come back for more help.

Thanks again

Mark
