Windows 2000: Do all the new features make the case for Win 2000 Server?

The new OS takes some giant leaps forward, but not without a few steps back
The release of Microsoft Windows 2000 occurred in February with promises from Microsoft Corp. that it would be stable, secure, scalable and manageable. How well did the company deliver on those promises?
Two reviewers, computer analyst and consultant Barry Nance and Irv Epstein, Unisys Corp.'s vice president for Win 2000 programs, assess the new operating system, focusing on its scalability, security, directory services and handling of applications. They also list what they like best and the things they think need improvement.
Microsoft Windows 2000 is both better and worse than its predecessor, Windows NT 4.0. It improves on NT 4.0 in areas such as scalability, power management and connectivity, but it requires greater resources'in computing power, money and maintenance expertise'and burns its bridges to many existing utilities and applications.
Most of my quibbles with the operating system are fairly minor, however. The key to understanding what's good and bad about Win 2000 is its biggest new feature, Active Directory. If you choose to upgrade to Win 2000, it will likely be because you find Active Directory a compelling way to organize your network.
Active Directory, a proprietary feature that works well with other Microsoft software but poorly with any other software, constitutes the biggest difference between NT and Win 2000.
Departments and agencies that use Microsoft software exclusively may find Active Directory's time-saving, well-organized representation of network objects a worthwhile reason to switch to Win 2000. Others, likely because they also rely on operating systems such as Novell NetWare or Unix, may choose to delay upgrading or perhaps even phase out Windows from their server environments and migrate solely to Unix.
Directory services
Active Directory is Win 2000's central repository for storing log-on identifications, passwords, shared disk and printer information and other network tidbits. You administer Active Directory via the easy-to-use Microsoft Management Console to add, change or delete users as well as define relationships among the servers on your network. Computers running Win 2000 automatically share Active Directory data among themselves, making Active Directory a single point of maintenance for network data.
Each server can play one of three roles in the Active Directory infrastructure: standalone server (not a participant in Active Directory), member server (member of an Active Directory domain, but not a domain controller), or domain controller. Active Directory predefines a great number of network parameters for you, and programmers can extend it even further with custom definitions unique to your organization's network.
Unfortunately, servers running NetWare and Unix cannot interface with Active Directory to obtain user IDs, passwords or file access permissions.
I'd give Microsoft a grade of B' for its excellent but proprietary design of Active Directory.
Security
Servers can run in mixed NT and Win 2000 mode, or in native Win 2000 mode, which precludes relationships with NT domains except through directory brokerage services. Running Win 2000 in native mode removes many of the widely publicized NT LANManager security problems that plagued NT Server and makes accessing network resources quicker and simpler for both end users and administrators.
Win 2000 derives its security from Active Directory. The Win 2000 Kerberos authentication system, which works closely with Active Directory, issues an electronic ticket when a user logs on to a particular server. The OS uses the ticket as a shortcut to authenticate a user to other domain controllers without forcing the user to log on separately in each domain. The entire process is encrypted and transparent to users.
But Win 2000 is not yet certified at the National Computer Security Center's C2 security level, which could slow its adoption by government agencies. Despite the company's best design efforts, Microsoft programmers had to make several changes to Win 2000's security functions in the last few weeks before the product's release.
Microsoft already shipped security changes in the first set of patches for Windows 2000. Keep in mind that, because of its prominence, Microsoft has become a popular target for
hackers.
Win 2000 earns a C for security.
