NDMP from NAS to basicdisk ( lun attached to media server)

Hey everyone, I cannot get the master server to see the lun attached to the media server as a NDMP destination, I have installed the ndmp license from the master server onto the media server. I do have NDMp running but it goes to the tape drives attached to the media server? Any ideas how to get this working???

Cheers in advance MattRobot Mad
