Why "at" doesn't work...?

Have another problem with my Command Prompt. The command "at" doesn't work. I use a limited account but I think it should work. When I type the command "at" a message appears: "Access is denied.". Do you have any ideas how can I fix this...?

Can you create a normal scheduled task under this limited account? I'm going to bet you can't. Anyways you can always use the runas command to execute the command under elevated user credentials.

If you're account is limited, you probably wouldn't be able to use at because it allows you to delete schedualed (<--- correct spelling needed here) events that may be used by other users.

At my school, the whole Command Prompt program is blocked.
