Active Directory Access Test

This test monitors the availability and response time from clients of an Active Directory server from an external perspective.

Target of the test : An Active Directory or Domain Controller

Agent deploying the test : An external agent

Outputs of the test : One set of results for every Active Directory server being monitored

Configurable parameters for the test
Parameters Description

Test period

This indicates how often should the test be executed.


The IP address of the machine where the Active Directory is installed.


The port number through which the Active Directory communicates. The default port number is 389.


The default value of this parameter will be none. In Windows 2003 environments however, the ADServerTest will function effectively only if a "fully qualified domain name" is provided in the this text box.


Provide the name of a domain user in this text box. This can be none for Windows 2000 environments.


Provide the password for the domain user specified above, in this text box. This can be none for Windows 2000 environments.

Confirm Password

Confirm the Password by retyping it here.


By default, this is set to 30 seconds. This implies that by default, the test will wait for 30 seconds to establish a connection with the target Active Directory server. If a connection is established within the default 30 second period, then the test will report that the server is available; if the test is unable to connect to the server within the default period, then it will report that the server is unavailable. If it generally takes a longer time for clients to connect to the AD server in your environment, then, you may want to change the ConnectTimeOut period so that, the test does not time out before the connection is established, and consequently present an "untrue" picture of the availability of the server.

Measurements made by the test
Measurement Description Measurement Unit Interpretation

Active directory availability

Indicates the availability of the server.


The availability is 100% when the server is responding to a request and 0% when it is not. Availability problems may be caused by a misconfiguration / malfunctioning of the server, or if the server has not been started.

Active directory response time

Indicates the time taken by the server to respond to a user query


A sudden increase in response time is indicative of a bottleneck at the server.
