I am not sure how you got into this state, but to clear it up you can edit the boot.properties file to enter (clear text) the username and password for the server (entered when running the Configuration Wizard).
The boot.properties file is located in your domain at:
<domain root>/servers/AdminServer/security
Just enter the username and password in the file:
username=myUserName
password=myPassword
WebLogic Server will boot up using these values and immediately encrypt the username and password in the file.
An alternate approach would be to delete boot.properties in which case WLS will prompt you for the id/pw each time it is started/stopped.
