Kevin, if you still see this behavior, the login screen reloads after entering credentials, try using the IP address in the browser address bar and not the DNS name. This same problem appeared on my iDRAC7s after updating the firmware to v1.50.50.  I've updated to v1.51.51 and still have the same issue.  Using the IP address is a workaround, though.
Hi there, I have a lot of Dell 610 and 510 servers all runing iDRAC Enterrise 6. All working a treat. We have recently got a new Dell 620 server, with iDRAC Enterprise 7. I have configured it, can ping it but cannot login in remotely. I have read all the other forum posts but stll havng trouble. I have tried IE8, Chrome, Firefox. I have added the URL to my trusted sites, deleted all the browsing data, removed the latest Java on my computer, installed the certificate but still no joy. I can still connect to all my other servers runing iDRAC 6, but wondered if anyone had any other ideas? Many thanks Kevin
