What ports need to be open for dnscmd.exe to operate?

I'm currently working with the Microsoft DNS command line utility dnscmd.exe to automate DNS record deletion in our datacenter. To complete this automation I need to be able to access a domain controller on another network to delete records from it, but I am unsure what ports I need to open for this to work. I've already opened TCP/UDP port 53 from my server to the DC, but no dice. Any feedback would be much appreciated. I've included the command I'm issuing and the resulting error message:

dnscmd.exe abc.xyz.com /enumzones

DnssrvEnumZones() failed.
    Status = 1722 (0x000006ba)

Command Failed: RPC_S_SERVER_UNAVAILABLE      1722 (000006ba)
