Recently my left alone computer locks out user

[PeterM]

I have to go to several computers in the company and make changes. I log on
as the administrator, and then when I'm done, I log out as the
administrator. About 30 minutes later the computer is locked, and I'm the
only one that can unlock it with the last admin log on password. This never
happened before, and we didn't change any profiles in all our Win XP Pro
computers. Since I don't know the users password, only the log-ons, I can't
log them on when I'm done. Is there anything I can do?. Also I wish that
there is a program that would show a little arrow to show the last several
people that logged on. I get about 20 calls per day about forgotten user
names. Many thanks for your kind help and advise......Peter

You didn't mention whether you checked to see if your screen saver had
somehow gotten password protected.

It's at "Display" on the Control Panel, select the Screen Saver tab and
there's a checkbox.

If you are using Windows xp,i guess you could fix it by check the
fast-user swith in CONTROL PANEL>>USER ACOUNTS
