MS Mail postoffice admin from win2k

I’ve just installed windows 2000 pro (new install) and in getting everything setup to admin my NT 4 servers I can’t seem to find the “Microsoft Mail Postoffice” control panel item that allows me to administer my MS Mail postoffice remotely. Does anyone know if and/or where I can install this program from? In NT 4 workstation it was in the “add/remove programs” -> “Windows NT setup”.

Thanks,

Dave
