DSQuery Command Line Tool for Active Directory 2003
New DS built‐in tools for Windows Server 2003
At last I have found a real useful member of the DS family of utilities. If I need to
find a user quickly from the command prompt, I call for DSQuery.
DSQuery Examples
Example 1 DSQuery to list all the OUs in your domain
Example 2 DSQuery User
Example 3 To list all your Domain Controllers
Example 4 To query the FSMO roles of your Domain Controllers
Example 5 To find all users whose name begins with smith*
Example 6 To filter the DSQuery output with o rdn
♦
Example 1 ‐ DSQuery to list all the OUs in your domain
Let us find how many Organizational Units are there in your domain? This command
will produce a listing of all OUs with this command.
dsquery ou dc=mydom,dc=com
or
dsquery ou domainroot
Learning Points
Note 1: dc does NOT mean domain controller, it means domain context.
Note 2: The dc commands are not case sensitive, but they dislike spaces.
dc=mydom, dc=com will draw an error.
Note 3: If you haven't got any OUs (Organizational Units), I seriously suggest that
you create some to organize your users.
Note 4: Best of all, in this scenario, you can substitute domainroot for dc=cp.
Example 2 ‐ To find all users in the default Users folder with DSQuery
In this DSQuery example we just want to trawl the users folder and find out who is in
that container.

dsquery user cn=users,dc=cp,dc=com
Learning Points
Note 1: The default users' folder is actually a container object called cn=users. My
point is if you try ou=users, the command fails.
Note 2: I queried users, however dsquery requires the singular user, not userS.
Other objects that you can query are computer (not computers!), group or even
contact.
Challenge 1: Substitute OU=xyz for cn=users, where xyz is the name of your OU.
Unfortunately, cn=users domainroot does not work.
Challenge 2: Substitute computer for user
Guy Recommends: SolarWinds' Free Bulk Import Tool
Import users from a spreadsheet. Just provide a list of
the users with their fields in the top row, and save as
.csv file. Then launch this FREE utility and match your
fields with AD's attributes, click and import the users.
Optionally, you can provide the name of the OU where
the new accounts will be born. Download your FREE
bulk import tool.
If you need more comprehensive software, download a
free trial of SAM (Server & Application Monitor)
Example 3 ‐ DSQuery to list all your Domain Controllers
Suppose you want to list all of your domain controllers, (not computers). Which
command do you think would supply the information?
dsquery server
dsquery server domainroot
dsquery server dc=cp,dc=com
Learning Points
Note 1: Amazingly, dsquery server, the simplest command get the job done.
Note 2: I thank Jim D for pointing out that we want here is the singular 'server'.
Example 4 ‐ To query the FSMO roles of your Domain Controllers
Here is a wonderful command to find the FSMO roles (Flexible Single Master Roles)

hasfsmo. The arguments, which correspond to the 5 roles are: schema, rid, name,
infr and pdc.
dsquery server hasfsmo schema
Learning Points
Note 1: The command is hasfsmo not ?hasfsmo as in some documents.

Example 5 ‐ DSQuery to find all users whose name begins with smith*
This DSQuery example shows two ways to filter your output and so home in on what you are looking for. Let us
pretend that we know the user's name but have no idea which OU they are to be found. Moreover, we are not
sure whether their name is spelt Smith, Smithy or Smithye.
dsquery user domainroot name smith*
or
dsquery user dc=cp,dc=com name smith* d
or plain
dsquery user smith*
Learning Points
Note 1: Remember to type the singular user.
Note 2: Probably no need to introduce *, you probably realize it's a wildcard.
Note 3: name is but one of a family of filters. desc or disabled are others.
Guy Recommends: Permissions Analyzer ‐ Free Active Directory Tool
I like the Permissions Monitor because it enables me to see quickly WHO has permissions to do WHAT. When
you launch this tool it analyzes a users effective NTFS permissions for a specific file or folder, takes into account
network share access, then displays the results in a nifty desktop dashboard!
Think of all the frustration that this free utility saves when you are troubleshooting authorization problems for
users access to a resource. Give this permissions monitor a try it's free!

Example 6 ‐ DSQuery to filter the output with ‐o rdn
The purpose of o rdn is to reduce the output to just the relative distinguished
name. In a nutshell rdn strips away the OU=, DC= part which you may not be
interested in.
dsquery user name smith* o rdn
Learning Points
Note 1: o is the letter oh (not a number). In my minds eye o stands for output.
Note 2: There is a switch o dn, but this is not a switch I use.
Summary ‐ DSQuery
Knowledge is power. The DS family in general and DSQuery in particular, are handy commands for interrogating
Active Directory from the command line. Perhaps the day will come when you need to find a user, computer or
group without calling for the Active Users and Computers GUI. Next try DSGet.

Guy Recommends: WMI Monitor for Powershell
Windows Management Instrumentation
(WMI) is most useful for PowerShell
scripting.
SolarWinds have produced this Free
WMI Monitor to take the guess work
out of which WMI counters to use for
applications like Microsoft Active
Directory, SQL or Exchange Server.
