Found the solution.  Looks like there was a old bug where when uploading a Active Directory cert it would replace the Dell SSL cert and we had some old m600s which never were fixed. To get the original Dell self-signed cert back the iDRAC firmware has to be on 1.11 and run "racadm racresetcfg". Anything above 1.11 doesn't seem to reset the cert. The other solution is to upload a CA signed cert.
Hello! We have some M600s that haven't been updated in a while and are still running iDRAC 1.11. When we update them to 1.65 they still do not have a Web Interface like some of our other M600s that have been kept updated over the years. Looking at Nmap scans and Wireshark it looks like port 443 is blocked even though it is set as the default in cfgRacTuning. We have tried resetting logs, configuration, and set different ports but no luck. We run CentOS 6.6 on these blades and our upgrade method is using the .bin file from the Dell site. Was wondering if maybe there is a different upgrade method for these with them running old firmware. Thank you, Stevie
