Recipe 3.12 Finding the Services a Domain Controller Is Advertising

3.12.1 Problem

You want to find the services a domain controller is advertising.

3.12.2 Solution

The following command will display the list of services a domain controller is advertising:

> dcdiag /v /s:<DomainControllerName> /test:advertising

You can also use nltest to get similar information:

> nltest /server:<DomainControllerName> /dsgetdc:<DomainName>

3.12.3 Discussion

The dcdiag /test:advertising command is a wrapper around the DsGetDcName method. DsGetDcName returns a structure called DOMAIN_CONTROLLER_INFO that contains the list of services a domain controller provides. Table 3-2 contains the possible values returned from this call.
