a) If you are trying to determine which user is accessing your network via
a Windows 2000 RRAS server, you can use Rasmon.exe: RAS Monitor utility
from the Windows 2000 Resource Kit. RAS Monitor is a GUI-based tool that
displays detailed information on remote access server connections.
b) You can also enable RRAS logging/tracing which will give you very
granular information. See this article for more details: http://support.microsoft.com/?id=313564
I hope that helps.
