Can you look at the portal.log an let me know what it says? Sometimes, the portal cannot connect to the Registry for whatever reason although it appears to be running.
Also, when starting the portal, I would wait a few minutes after starting the Registry to ensure that the Registry is completely up and running.
At the bottom of the login window, does it show the Registry name?
This just looks like Portal is not connected to the Registry correctly.
A webex would be beneficial. You can create a support case at http://support.ca.com or call 1-800-225-5224 and we will be able to set up a webex.
