Mission Critical Software Inc has released a security administration program for large Windows NT installations that lets companies slice up their networks into small chunks, each of which can be controlled by sub-administrators. The Houston company describes the process used by Enterprise Administrator 4.0 by characterizing the network administrator as a marshal who doles out territories to deputies, each of whom is responsible for the security of his little corner of the network – only a Texas company could think of such a comparison, we think. The whole idea is that centralized administration on very large networks is a complex mess, making even simple administrative tasks such as resetting passwords or granting resource access a chore. Enterprise Administrator consists of a server that runs on the primary domain controller of each domain plus client software for NT Server, NT Workstation and Windows95 or 3.1 platforms. Pricing is $900 per managed domain plus $14 for each user account defined in those domains.
