Question : tracking down a username without NET SEND

I know the easiest way would be the following:

NET SEND {username}
NBTSTAT -c
{username} will be listed next to IP address
PING -a {IP address} will resolve name

If NET SEND has been disabled in our office, how would I track down a username to the IP or computer name?

Answer : tracking down a username without NET SEND

Well there's PsLoggedOn from SysInternals:

And it can be done using WMI if I remember correctly. The downside is that the WMI version would need writing whereas PsLoggedOn is already done.

The problem with each of these is that they can take a long long time to run (depending on the number of computers of course).
