    One alternative (if this is a 2000 server) may be to install terminal
    services on the server in question, in remote administration mode, configure
    the RDP connection to allow auto logon, then set up a TS connection for the
    user that has the administrative user name and password already entered into
    it. The user will not be able to see the password, and when initiating the
    connection, will be automatically logged on to the TS server. Note that by
    default terminal services does not allow this automatic logon; you must
    configure it to do so. If you don't, the user will still be prompted for a
    password in the logon dialog box, which would defeat the purpose.

    With that said, depending on the application in question, there may be
    better ways to allow a user administrative capabilities for the app without
    granting him/her administrative capabilities for the machine.

    HTH,

    Laura Robinson
