    some students here are having this problem, usually after a student has logged off, i just tell them to restart and it solves it. Never able to find out why.

    I noticed this one on machine in a primary school the other day. I was shutting it down anyway so didn't bother I just thought it was a random funky windows problem...

    You can use START+L key combo to lock a home machine just like a pro one

    I've seen this problem once which was years ago, not seen it since. I had no choice but to power it down by pressing the power button. All was well afterwards!

    no-ones RDP'd to the machine?

    It can cause a funky lock on the machine, and the sessions not finished properly it can do this

    could be the kids have found they can RDP (there's a version you can install on a USB stick). Who did it say it was locked as..?

    nope no-one has. The kids cant run .exe's so i doubt they have managed to get into it.

    No you can't! Start+L on a machine which isn't on a domain will only take you to the welcome screen. It doesn't even lock my XP Pro machine here which isn't on a domain.

    Come accross this: dont know if it is the answer as i have never experienced this problem before but worth a try/

    Turn off the power management for the NIC. When the computer goes into standby mode, it will generally turn off power to the NIC, which in turn drops the network connection.

    Since you no longer have a network connection, hitting CTRL-ALT-DEL will bring the screen up, but there is no way to authenticate the user.

    Regards

    James

    Not on a domain - all the Windows Key + L does is take you to the Logon screen.

    It takes you to the login screen yes but if you have set a password on your account you will need to enter it to continue.

    I've never seen this problem but it stinks of Remote desktop.

    I have had a problem with the Windows 2003 server not being able to be unlocked if a remote desktop session connection is not ended properly. This happens fairly often for us.
    I know this problem and it is a PITA. Very similar to when the number of RDP's gets maxed out and you have to reset it.

    This might be crazy but have you RDP'd to it yourself and seen what happens?

    Try and RDP it as admin whilst it is locked and observe its behaviour.
