If you’re looking for a way to restrict when certain users can log on to Windows XP, here’s a simple little example from Doug Knox:
1) Open Help and Support and type "logon hours" (without the quotes) in the
search box.
2) Go to Full text matches and click on "Net user". See the examples for
setting a user’s logon hours. Some examples would be:
net user johnsw /time:M-F,08:00-17:00
net user johnsw /time:M-F,8am-5pm
net user marysl /time:M,4am-5pm;T,1pm-3pm;W-F,8:00-17:00
net user johnsw /time:all (this one means this user can always log on)
3) Open a Command Prompt window.
4) Enter the appropriate "net user" command for the user(s) you wish to restrict
access for.
Notes: This works for basic users and can be pretty effective if users are required to use a password to log on. This would be a good way to restrict children from logging on to Windows XP. Please keep in mind that this will keep a user from logging on to the system. It will not cause them to log off when their hours “expire”.
