The iDRAC dislodged itself when I was installing the new RAM. Reseating the iDRAC card did the trick.  Didn't realize that when the iDRAC dislodged itself, the server automatically put the iDRAC system into sharing LOM 1 on the expected iDrac IP address. After reseating the card and going into to the iDRAC with ctrl+E to change the iDRAC\lan settings\NIC Selection back to Dedicated instead of Shared, everything was back to normal. Thanks Robert and Trodai0080 for the help.
I recently added ram in a dell r510 and upon doing so my License for iDRAC 6 Enterprise reverted to Express.  After changing the hardware modification back to how the server shipped, the license remained at Express.  How would I go back to my enterprise License the server shipped with.  I don't have any license codes only the service tag where it shows the r510 shipped with enterprise.  I also don't know where I would enter a license key to upgrade/fix this problem if I had a license.  The iDRAC 6 wiki only shows "iDRAC6 Licensing Information <ADMIN NOTE: Broken link has been removed from this post by Dell" for the licensing information section. Will resetting the iDRAC back to factory defaults fix this? Will reverting back to previous firmware settings fix this, (note: my previous firmware settings match my current v1.8 iDRAC) Is there anyway to save the settings within the iDRAC web interface that won't save the fact that it's a Express install? The server is currently running iDRAC 1.8.  Any help would be appreciated.
