Windows Server 2003 Gains Traction
The Windows Server 2003 rollout is rapid, according to a new survey. Key drivers are security, Active Directory and Exchange 2003.
Growing requirements around security, Active Directory and Exchange Server
are propelling widespread adoption of Windows Server 2003, according to
a new joint survey of ENTmag.com
and Microsoft Certified Professional
readers. Six out of 10 Windows sites are already in some
stage of rolling out Microsoft's latest server operating system.
But most Windows Server 2003 migrations are focused on practical front-end
or departmental functions in the enterprise, such as Web serving, e-mail
and file/print services. Only a limited segment of companies plan to deploy
high-end enterprise applications such as ERP or data warehouses on Windows
2003. And only a handful of organizations are considering moving to 64-bit
versions of the operating system. Also notable is the scant consideration
being given to enhancing Web services capabilities. Despite the enormous
industry attention being devoted to Web services, Microsoft's .NET Framework
isn't even a blip on the radar screen for many IT shops making or considering
the move to Windows 2003.
The survey covers a range of companies and industries from mainly across
North America and finds rapid adoption of the new OS taking place.

Most Windows shops are now in the process of moving at least some applications
to Windows Server 2003. The only companies holding back are those that
just completed a move to Windows 2000.
The survey of 163 IT managers and executives confirms that 60 percent
of Windows sites either already have Windows 2003 in production or plan
to do so very soon. As shown in Table 1, one in six companies currently
has the OS in production, and 43 percent have migrations in progress.
Another 20 percent of Windows shops aren't ready to commit to a timeline
for Windows 2003, but say they'll deploy the new OS on a case-by-case
basis as older applications are replaced. The survey also finds that among
the 20 percent of companies that don't have any plans to migrate, more
than a third say it's because they've just completed a migration to Win2K.
Once the migration process is underway, respondents plan to ramp up to
Windows 2003 fairly quickly across their enterprises. Currently, 63 percent
of companies in the survey report that more than half their servers are
running Win2K, as shown in Table 2. Within a year, a majority, 52 percent,
expect to be running Windows 2003 on most of the servers across their

Most enterprises are moving to Windows Server 2003 for new security,
e-mail and Active Directory features. Few are attracted to 2003 for its
.NET capabilities, however.
In an era of rampant viruses, worms and hacking incidents, security is
driving many migration efforts to Windows 2003. Windows platforms and
applications have been a highly publicized target for malicious code writers,
bringing Microsoft considerable pressure to deliver more secure systems
and a more manageable approach to patches and updates.
In the survey, security is cited as one of the top three leading reasons
for migrating to Windows 2003, with almost one-sixth of the group, 16
percent, calling it the primary driver for moving to Windows 2003 (see
Table 3). A large majority, 77 percent, cite security as a secondary reason
for deploying Windows 2003. New security features in Windows Server 2003
include a Local Security Authority, new Local Service and Network Service
accounts, credential caching for alternate names and passwords and better
protection of cryptographic elements from unauthorized password resets.
Active Directory, a key component of the Windows 2003 security infrastructure,
was itself another key factor cited in migration plans. Microsoft's latest
version of Active Directory features the ability to store up to a billion
objects, multiple domain controllers, better replication engine performance,
and trusts that interface with multiple domains. About one out of six
respondents, 17 percent, indicate they're moving to Windows 2003 to take
advantage of Microsoft's directory services (Table 4), while 37 percent
cite this as a secondary reason.
The need to upgrade to Exchange Server 2003 is also driving many migration
plans, the survey finds. About 16 percent cite this as their single main
reason for moving, while a majority, 59 percent, list it as a secondary
Alleviating the reboot problems endemic with prior versions of Windows
is driving many upgrade plans as well. More than eight percent say this
is the single most important reason, and two-thirds cite this as a secondary
reason. At least one respondent, however, cautions that Windows 2003 isn't
entirely free of these problems. "Windows Server 2003 still appears
to have memory and thread management problems," said the IT manager
at a large financial services company. "We still have to reboot our
Windows Server 2003 servers periodically, particularly after deploying
Ranking surprisingly low in the list of priorities in migrating to Windows
2003 is the desire to more effectively implement Microsoft's .NET Framework-based
Web services. Microsoft has positioned .NET as the cornerstone of its
enterprise strategy going forward, but it appears more practical operational
issues are driving Windows OS migrations. Only one company cited .NET
as a primary reason for moving to the newer OS, and only 19 percent rank
this feature as a secondary driver.
Few, if any, Windows site managers are turning to Windows 2003 for 64-bit
Other enterprise-class attributes — including logical partitioning,
clustering and scalability — rank low on the priority list and only
surface as secondary reasons.

Windows Server 2003 will mainly be deployed for tried-and-true Windows-style
applications, not high-end enterprise functions.
To a large extent, Windows 2003 will be picking up the mantle of applications
first deployed in Windows NT and carried forward to Win2K. Large majorities
of respondents expect to be deploying such tried-and-true Windows functions
as file-and-print functions, e-mail, and Web servers. A majority, 53 percent,
also report they'll be deploying Windows 2003 to support transactional
As Table 5 shows, those Windows sites expecting to deploy applications
traditionally associated with Unix or large legacy systems — including data
warehouses and ERP systems — remain in the minority. While it remains to
be seen how many, and how fast, large enterprise applications move to
Windows, many respondents are satisfied with the enhanced features. "I
do sleep better running enterprise applications with Windows Server 2003
than NT 4," said the IT administrator at a large financial services

Most Windows sites do not plan to grow beyond two-way multiprocessing.
Windows 2003 is touted to have multiprocessor scalability similar to
that achievable through more high-end systems such as commercial Unix.
The operating system supports ccNUMA (cache-coherent non-uniform memory
allocation), which more tightly lashes memory resources within multiple
processors into a single location.
However, most current and planned Windows 2003 sites don't plan to have
boxes scaling beyond two-way configurations. (As noted above, scalability
ranks relatively low as a reason for moving to Windows 2003.) A majority,
51 percent, say their largest servers will support two-way systems, while
another 34 percent plan to advance to four-way systems. While there's
much discussion and new tools emerging to support Windows server implementations
on eight-processor servers and higher, only 16 percent of sites in this
survey plan such large systems. In fact, only two respondents (or 1.5
percent of the current or planned Windows 2003 sites) say they intend
to eventually roll out a 32-way server (Table 6).

Respondents have mixed opinions about how Windows Server 2003 compares
to commercial Unix flavors in terms of overall scalability and system
robustness. "It's real close," said the IT manager at a large
East Coast university. "The stability isn't there yet but closing
in quickly. The features, in our opinion, [outstripped those of] Unix
a long time ago. The basic management features are excellent and the added
ones — such as MOM and SMS — are even better."
