The customer has just created a CIFS server, he is now trying to create a vdm on the data mover and is unable to.

This is the command he used to create the CIFS server:
server_cifs ENG -add compname=EMC2,domain=corp.emc.com

Why is he unable to create the VDM?

A.
VDM can be created if you stop and start CIFS first, then create the VDM

B.
Customer never joined the CIFS server to the domain, and therefore the VDM will fail

C.
Customer has created a default CIFS server, which uses all interfaces. There are no free interfaces available

D.
Customer created a default VDM, which uses all interfaces, there are no free interfaces available
