The three scripts provided here allow one to establish if a user exist on a Windows domain, without providing any authentication. These user enumeration scripts use the DsrGetDcNameEx2,CLDAP ping and NetBIOS MailSlot ping methods respectively to establish if any of the usernames in a provided text file exist on a remote domain controller.
Requirements: impacket >=1.5, scapy >= 2.4.0, asn1tools >= 0.53.0
Notes: Python 2 is recommended for all scripts, and is required by the UserEnum_NBS.py script. For the UserEnum_LDAP.py script, one should specify the FQDN, i.e. CONTOSO.COM instead of CONTOSO. The UserEnum_LDAP.py script seems to be the fastest.
