When you run User Manager or Server Manager to add a new user or to change a current user's password, the encrypted-password-block goes through the network, exposing the password in plain text. The server makes a call to the remote client without encrypting the password data.

This behavior can occur if you use NTLMv1 (Windows NT LAN Manager version 1) on a server that runs Microsoft Windows 2000 Server.
