Changing Windows NT Password Progmatically

Changing Windows NT Password Progmatically

Question:
How can I change my Windows NT server password through a program?

Answer:
Actually, this is rather simple. However, heed the following precaution from the MSDN documentation on this function:

“A server or domain can be configured to require a user to log on before changing the password on a user account. In that case, only members of the Administrators or Account Operators local group or the user himself can change the password for a user account. If logging on is not required, the user can change the password for any user account, as long as the user knows the current password.”
