Re: Help with smb-enum-users.nse

[Abuse 007 <abuse007 () gmail com>]

Hi Ron,

It's a client's DC, part of a pentest engagement so the information is
a bit sensitive.

I can try to replicate it in a test environment but it will take some
time for me to set it up.. :(

I've download some material on SMB, RPC, etc., and I'm doing some
research on how it all works, and analysing winfo.exe's behaviour.
I'd appreciate any pointers to what the issue may be or to good
material for research. SMB/CIFS/MSRPC is quite a beast.

Thanks,
Ab
