Using port 139 throws: "socket.gaierror: [Errno -5] No address associated with hostname"

[NeodymiumFerBore]

Running the exploit using port 139 throws the following error:

socket.gaierror: [Errno -5] No address associated with hostname

(My DNS is set up correctly, I'm able to resolve DC1, dc1.lab.lan, reverse lookup 10.0.0.10)

Same result by specifying -target_machine. Full command: ./zer0dump.py -port 139 -target_machine DC1 DC1. Tried multiple combinations, using IP, fqdn or NetBIOS. I don't know much about Netlogon, hard to troubleshoot for me.

Appart that, no problem with port 445.

Note: using impacket 0.9.22.dev1+20200915.115225.78e8c8e4 instead of the one in your requirements.txt. It was throwing other errors at zer0dump runtime.
