Error when deploying Kinetic Application Server

I am trying to add an App Server through Admin Console (I have done this 2 times previously) in our Sandbox Environment. Every time I attempt to deploy the server, I get this error:

Application Server Setup Failed.
Errors:
System.IO.IOException: The password for this account has expired.

Please Help

Are you sure the account you are logged in with has not expired, or the service account you are using for the custom account on your application pool has not expired?

Maybe your account expired after you logged in.
