Trying to get administration account unlocked

Hi, I am having real problems with trying to activate the adminsitration
account on vista home premium 32bit. I have tried going on the computer
management but i can not find the "local users and Groups" folder to
open and go to the Administration. I have tried using the cmd to,
putting in exactly "net user administration /active:yes" but it comes up
with error 5 and access denied. I used the "net user" etc. on the cmd
before and managed to get a message, the message wern't though
"administration account activated. I restarted the computer to see if it
would show the admin account on the log in screen but it didn't. I need
to know what to do to get into admin account, can someone help me
please?
