hi since i found these two commands i often use in my WAN, since i can't touch the server physically.
the first one is the runas command:
just to open application in administrator privilege, there i use command prompt as an example. but there are some program that can't be open using runas command and have the admin privilege, one of it is the mmc related command like windows services...

the second one is to change the user password,
here you'll be prompted for the new password for the user administrator.

i often use it because sometime my remote application cannot do ctrl+alt+del (log off), so i need someone from the remote server to logoff there and use the temporary password of administrator.

another thing is a bootable cd to reset the password of the user.
so if you forgot to create a forgotten password disk like in this thread:

you can reset the password to blank using this bootable cd.
you can more info and download the software here:
