Windows Cannot Map Mac Volume


I have a Mac Server with Xraid. The Mac desktops can connect to the Mac server, but my intel desktops cannot map the drive. I have active directory integrated with the Mac. Set up in Directory Access. I'm missing something and don't know what it is. I have another Mac server that I can connect to, but can't find the differences. Any suggestions ?

when I try to map to it I get the message
"The mapped network drive could not be created because the following error has occurred: The account is not authorized to log in from this station.
