if you're in the US, call 1-800-624-9896, have the service tag or express service code handy. I should note that the order number that the system is on should show that the system was ordered with an Enterprise license, or you should be able to provide the order number if it was purchased separately from the system.  #Iwork4Dell
We had to replace a MB on a R720XD recently as the idrac module on the original MB failed.  Unfortunately due to the idrac failing we were not able to retrieve the license we had.  What would be the best way for us to contact Dell so we can get a copy of the license to apply? Thanks
