Hello, i well received the service tag in private. If I'm not mistaken, the operating system was not OEM purchased with this server so we cannot escalate the CAL issue internally. I recommend that you check with Microsoft or the operating system vendor.RegardsMarco
Heelo    I have a new PowerEdge R740  . With the server we purchased 5 users CAL license ( We got only a certificate whic approve is was purchased for us by the seller .  According to Microsoft support once I activated the server ( Activate server option is available after the installation of the necessary services) , no need to perform anything else . However every time I restart the server I get a message saying "Remote desktop licensing mode is not configured" along with the number of days I have left until it will be expired . So to me it seems I still need to complete the activation ...    Any help would be much appreciated
