This test periodically monitors the network connection between the mailbox server role and each identified domain controller, so that communication bottlenecks are swiftly identified and resolved.

The default parameters associated with this test are as follows:

• The TEST PERIOD list box helps the user to decide how often this test needs to be executed. 

• In the HOST text box, the IP address of the Mailbox server has to be specified.

• The port number through which the Mailbox server communicates has to be specified in the PORT text box. By default, this is 691.

• Once the necessary values have been provided, clicking on the Update button will register the changes made.

When changing the configuration for specific servers, a “*” beside the text box corresponding to the parameter signifies that these values have to be manually configured by the user. The parameter values that require to be configured will typically be prefixed with a “$” or contain a series of “*”. A value of "none" in the parameter value indicates that the corresponding parameter value can be changed if required.
