Nlmon.exe - Windows 2000 Resource Kit Utility
|Nlmon.exe - NL Monitor
This command-line tool can be used to list and test many aspects of trust relationships. NLMonitor uses the Computer Browser service to enumerate domain controllers. Therefore if browsing is not working correctly, NLMonitor may produce inconsistent results. Also, the computer where NLMonitor is run, and also those providing the browsing services, must share the same protocols that are used by the domain controllers to carry out their domain activity.
