70-294: Active Directory Planner
Learning how to work with directory services is a long journey that involves trusts, policies and organizational understanding, along with the tools that make the operating system hum.
The new 70-294 exam about Active Directory requires specific knowledge
and working experience with Windows Server 2003 forests, domains, sites,
Group Policies and trusts. You'll be required to prove your knowledge
of AD administration. Proving your design skills with AD comes later in
exam 70-297. If you take these MCSE exams in the suggested order, after
passing 70-294, the Active Directory design exam should be much easier
since you'll be familiar with Active Directory from A to Z!
If you tackled 70-217, the Windows 2000 directory services infrastructure
exam, you'll find differences. In the new test, you'll encounter questions
relating to new technologies such as forest trusts, universal group caching,
and forest and domain functional levels.
For this review, I tackled the beta version of the exam. Let's look at
what you'll need to do to prepare.
Planning and Implementing AD
The first exam objective, Planning and Implementing an AD Infrastructure,
includes a myriad of topics: proper planning and placement of global catalogs
(GCs) and FSMOs (Flexible Single Master Operations); forest, domain and
site structures and topologies; and administrative delegation.
The rule of thumb remains the same: one GC per site. A GC is a domain
controller that holds a copy of all objects in a forest. It's created
automatically during installation of the first domain controller in the
first domain. GC functionality can be added to other domain controllers
with the AD Sites and Services snap-in. GCs support AD in the following
scenarios: They allow users to finds objects and supply UPN authentication
and universal group membership lists. New to Windows Server 2003, DCs
can be enabled to support universal group (UG) caching. UG caching is
also enabled with the AD Sites and Services snap-in. UG caching speeds
logon times, eliminates the need for extra hardware and minimizes bandwidth
usage since only UG memberships are replicated.
Not much has changed since Windows 2000 in regards to FSMOs except they're
now more commonly referred to as "operations master roles servers."
There are five in all: schema master, domain naming master, RID master,
PDC emulator and infrastructure master.
Tip: Your best bet when preparing for operations master
roles servers questions on this exam is to refer to this short KnowledgeBase
article, "FSMO Placement and Optimization on Windows 2000 Domain
here) on flexible operations master roles servers.
Requirements for three of the certification paths toward the MCSE
on Windows 2003. Exam 70-294 is required for those starting afresh
and candidates who've already obtained an MCSA on Windows 2000. Candidates
with an MCSE on Windows 2000 can bypass this exam.

Windows 2000 forests and domains are readied for Windows 2003 DCs with
the new utility ADprep.exe. ADprep helps make sure that a Windows 2000
forest and domain contain the additional objects, attributes and permissions
to support the Windows 2003 AD environment. ADprep offers the following
- adprep /forestprep: runs forest upgrade
(must be completed first)
- adprep /domainprep: runs domain upgrade
Tip: DCpromo is used to promote a server to the domain
controller role for a domain.
Domain functional levels are an extension of the mixed/native mode concept
introduced in Windows 2000. Using the AD domains and trusts snap-in, you
can scan, view and change the domain functional levels.
Domain functional levels are as follows: Windows 2000 mixed (default,
with all DC types supported, NT 4.0, Win2K, Windows 2003), Windows 2000
native (Win2K and Windows 2003 DCs only), Windows 2003 interim (a special
mode used during an NT 4.0 to Windows 2003 upgrade) and Windows 2003 (Windows
2003 DCs only). In this last mode, the new utilities for domain controller
and domain rename are available and support for cross forest trusts exists!
You can download the domain rename tools by clicking

Planning Active Directory
This exam, an update to 70-217, will test your knowledge
of Windows Server 2003 forests, domains, sites, Group
Policies and trust relationships.
Available August 28, 2003
Planning, Implementing, and Maintaining a Microsoft
Windows Server 2003 Active Directory Infrastructure
Who Should Take It
Core for the MCSE on Windows Server 2003
An Active Directory structure includes the forest root domain, child
domains, application data partitions, domain controllers, functional levels
(as noted above) and trust relationships. This TechNet article on Active
Directory partitions (click
here) describes their benefits and use.
Other than the default, implicit, two-way, transitive trusts that are
created automatically when Windows 2000 and Windows 2003 domains are present
in a forest, the available types are:
- Explicit domain trusts. Relationships that you create yourself
as opposed to those created automatically during the addition of domains.
You create and manage trusts using the AD Domains and Trusts snap-in.
There are two types of explicit trusts: external and shortcut. External
trusts enable user authentication to a domain outside of a forest. Shortcut
trusts shorten the trust path in a complex forest.
- Forest trust. This allows an easier method of resource sharing
when business needs whether planned or unplanned, have complicated things.
This document (click
here) is required reading for this exam and sums up multiple-forest
The final topic in this objective is administrative delegation. Designing
your forests, domains and OUs for administrative delegation is the primary
reason for such a hierarchy. Be prepared to tackle questions in which
you need to decide which hierarchy of domains and OUs will allow the most
efficient placement of Group Policies. Understanding the inheritance behavior
of Group Policies and the options Block Policy inheritance and No Override
will certainly help in the testing center! Read "Introduction to
Group Policy in Windows Server 2003" (click
here) for more.
Exam 70-294 is a core requirement for anyone wanting
to be certified as an MCSE on Windows Server 2003 (see
Table 1 for the
other exams you must take). Of course, if you're already
certified on Windows 2000, you can bypass this one and
go straight to 70-292 and 70-296 for the MCSE upgrade.
These exams won't encompass a beta testing period since
they'll include questions from other Windows 2003 exams
such as this one.
Managing and Maintaining AD
The next exam objective, Managing and Maintaining an Active Directory
Infrastructure, tests your expertise in managing a forest and domain structure,
configuring site replication schedules, link costs and boundaries, monitoring
AD and FRS replication and authoritative and non-authoritative AD restore
operations. The best place to start is with all the administrative tools:
- Active Directory Users and Computers (ADUC) for domain user and group
- Active Directory Sites and Services (ADSS) for site management
- Active Directory Domains and Trusts (ADDT) for domain trust management
- Replmon (AD Replication Monitor) for monitoring replication links
- Event Viewer, of course, for its application and system logs
Tech Tip: Sonar.exe is a command-line and GUI version tool
available for Windows 2000 and Windows 2003 that allows you to monitor
the file replication service of replica members in order to monitor traffic
levels, backlogs and free space.
Using these tools and understanding their capabilities and limitations
will be invaluable in your work with AD. Replmon is slick! It's installed
from the Support\Tools directory of the product CD and offers many AD
replication statistics and logs. It allows you to show replication topologies,
available GCs and FSMOs, BridgeHead servers and trust relationships, to
name a few.
Active Directory Services Interface (ADSI) Editor, a low-level editor
and search tool, is also one of those tools you can't do without when
managing AD. DCdiag is another useful tool that can query the state of
a domain controller, report any problems and assist in troubleshooting.
Using the advanced server boot option, "Directory Services Restore
Mode," along with NTDSutil.exe, you should be prepared to address
questions involving AD authoritative and non-authoritative restores. Review
this brief KB article (click
here) prior to taking the exam.
Tip: An authoritative Active Directory database restore
on a domain controller occurs after a non-authoritative restore and designates
the entire directory, subtree or individual object restored to be the
most recent. This one will be synced to other all DCs.
User, Computer and Group Strategies
The third exam objective, Planning and Implementing User, Computer,
and Group Strategies, tests your abilities in planning a security group
and user authentication strategy with password policy, as well as planning
and implementing an OU structure. I strongly suggest you review chapters
two, three and four of "Windows Server 2003 Deployment Kit: Designing
a Managed Environment" (click
I also recommend that you refer to my earlier discussion on administrative
delegation and the resources I suggested. Remember that a Windows domain
is a "security policy" boundary and only one password policy
per domain is supported.
In implementing an OU structure, be sure you understand the hierarchy
of domains, OUs and child OUs. The TechNet article, "Designing an
OU Structure that Supports Group Policy" (click
here), will get you started.
There are a few new delegation of authority permissions types when you
right-click an OU and select Delegate Control, including the RSoP (Resultant
Set of Policies) planning and configuration modes. Understand how and
where delegation of authority can be used.
Tip: To move objects within an OU hierarchy, simply right-click
and select move.
Things To Practice
- Plan, deploy and manage Group Policies with GPMC
and RSoP. You'll need to download the GPMC add-on
for Windows Server 2003 and practice, practice, practice.
- Plan, deploy and manage forests, domains and OUs.
Even with only one server, you can still perform all
the necessary planning, deployment and management
you'll need to master in this topic.
- Create and manage inter and intra-forest trust relationships.
With at least two servers or VMWare, you can create
multiple forests and trust relationships.
- Troubleshoot AD. There's no easy way to master
troubleshooting so try anything you can think of in
your lab to get experience. the TechNet article, "Active
Directory in Windows
here) and understand the possible errors
diagramed in the flowcharts.
- Create and configure Group Policies. This is easy
enough if you spend the time and understand what's
required. There are over 200 new GPO settings available
in Windows Server 2003. With the new Group Policy
Management Console, this is easier to understand than
it was with Windows 2000.
- Configure sites, links, bridgehead servers and
cost. With at least two servers or VMware, you can
configure sites, links, bridgehead servers and replication
cost values even if you don't have separate network
segments. With the ADSS snap-in, this becomes easier
the more you practice.
- Raise the functional level of a forest and domain.
This is something you'll really want to dig into,
as it can be complicated. Using either the ADUC or
ADDT snap-in, right-click the domain and select Raise
- Enable universal group caching on a DC. This is
an easy task but a new feature, so be sure to try
it at least once. Using the ADSS snap-in, right-click
the server's NTDS settings and select Enable Universal
Group Membership Caching.
- Explore all the reporting features found in Replmon.
Load the support tools from the CD and explore this
invaluable tool even if you don't have a complex AD
lab. Check the Server Properties option while you're
- Understand the modes of RSoP and when they're most
useful. This exam topic is present in the 70-293 exam
so it's time to get a handle on all that RSoP offers
if you don't already have one. Use the planning and
logging modes against your newly created GPOs from
# 1 above.
Planning Group Policy
The next objective is Planning and Implementing Group Policy. The
topics included here range from planning a Group Policy strategy for users
and computers to configuring the user environment using Group Policies
and deploying a computer environment using Group Policies. Did I mention
that this exam might include a lot of Group Policy-related questions?!
There are many resources available to bring you up to speed with Group
Policies. I suggest you pick up a book on the topic. Some have been out
for a few years and still withstand the test of time. Others will be released
by the time this test surfaces.
I also suggest you read the Group Policy Management Console white paper,
"Administering Group Policy with the GPMC" (click
Tech Tip: Download the GPMC add-on (click
Managing Group Policy
The final objective in this exam is Managing and Maintaining Group
Policy. This objective includes such topics as troubleshooting issues
related to Group Policies using tools such as RSoP and GPresult and maintaining
software using GPs.
When it comes to troubleshooting, here's the number one recommended resource
besides hands-on experience: "Troubleshooting Group Policy in Windows
Server 2003" (click
For maintaining software using GPOs, I refer you back to the "Windows
Server 2003 Deployment Kit: Designing a Managed Environment book,"
chapters eight and nine (click
Tip: GPresult must be run from the local computer where
the user is logged on to and Group Polices are applied. Along with the
/u or /c switch, you can find the applied GPOs for the user or computer

Study resources for Windows Server 2003 can be found
within the help and documentation of the product. Of
course, you'll also want as much hands-on practice as
you can obtain. If your company hasn't made the move
yet, work with the 180-day evaluation (click
There's also a lot of information available online
from Microsoft such as at the Windows Server Community
One of the best study resources I found for this exam
is the "Windows Server 2003 Security Guide,"
which you can download by clicking
You can also take the Microsoft official training course
at your local CTEC from an MCT:
Planning, Implementing, and Maintaining a Microsoft
Windows Server 2003 Active Directory Infrastructure
Microsoft Press offers this self-study material:
If you've been following along with this series of exam reviews,
then you know that this wraps up the core server tests you'll be tackling.
Add a client test, as well as some electives, and you'll be able to call
yourself an MCSE on Windows Server 2003. In the course of doing that,
you'll have strengthened your knowledge of networking, directory services,
security and more. That, in turn, will enable you to do your job more
effectively and tell the listening world that you're at the front of the
latest operating system technology from Microsoft. I consider this a worthy
goal for an IT professional—and I wish you good luck in your pursuit
