My XpPro comes up with the username and password, and always has done. I guess that is to do with the networking security (or you might as well be using Win98 ) I see an incon in the tray that tells me a network cable is unplugged, so I must have networking enabled.

The power management thing has been a potential issue with Win98/ME and XP. I normally switch it off, but then I don't run my machines 24/7.

I would suggest that you go into <control panel> and <power option> and systematically check all the settings. Then boot into the BIOS and see what power management settings you have there.

Plese remember to look at the "advanced settings" in XP and make sure that it has the right instructions for what to do when you go into standby/sleep.

Also please check what the settings are for the various user accounts you have set up.

just a few thoughts
