In theory you could install a remote admin package, but anyway, you can (I think) use the Computer Management tool in Administrative Tools on a 2000 or XP machine to view server manager on an NT Server.

So, from my own desk in work (A Windows 2000 Professional Workstation) :
Start > Settings > Control Panel > Administrative Tools > Computer Management
Action > Connect to another computer
I put in, for example, our PDC's name : NT1

I can then go into :
Computer Management (NT1) > System Tools > Shared Folders

From there I can look at :
Shares, Sessions & Open Files
