Win2K & NT4 & Others under 1 screen

[Guest]

I would like to know if there is a way to control a combined network of WIN2K, NT4 and maybe others from 1 screen. That means making normal NT4 policy's, win2K group-policy's and controlling Novell mounted volumes and the microsoft mail mailboxes and all that from hyena. Can this be done? Obviously it would involve scripting...
I know vb can be used for microsoft OS's but wat could be used for novell&Unix?
