Windows: user and group enumeration

Enumerating Users via NetBIOS: usernames and (common) passwords. Enum: use and output. DumpSec: output.
- Countermeasures: as before (close ports, no NetBIOS over TCP/IP)

Enumerating Users using SNMP: SolarWinds IP Network Browser . See also snmputil and read more in the book.

Windows Active Directory enumeration using ldp: Win 2k on added LDAP through the active directory -- you login once (the good) and have access to all resources (the security problem).
- Threat and countermeasures in the book (better dealt with in Operating Systems):
  - close ports 389 and 3268,
  - upgrade all systems to Win2k or above before migrating to Active Directory.
