In Case 2 you mention an NT MLM  Where can I find more information on
I was not aware that there was an NT MLM at all.  I have one environment
which is all NT and would like to implement NetView for NT on one box
disribute MLMs on remote NT server nodes.  Can you point me to further
information on this?

Thank you,
