‘Forgot Password’ (Password Reset) in QC not working

When a user clicks the ‘Forgot Password’ function, they don’t receive any email (nothing happens). I have tried the following:

1) Log into Quality Center siteAdministrator
2) Click Site Configuration tab
3) Click Settings down arrow button
4) Click Set Mail Protocol
5) Click the radio button for the SMTP server and enter the correct IP address or naming convention of the Server where SMTP services are running.
6) Click Test… Add an email to "send to" "test issuccessful" should appear.
7) After done with the test – click OK
8) Log out of QC Site Admin and restart the QC server

What else needs to be done here ?
