3.12. Finding the Services a Domain Controller Is Advertising
Problem
You want to find the services a domain controller is advertising.
Solution
The following command will display the list of services a domain controller is advertising:
> dcdiag /v /s:<DomainControllerName> /test:advertisingYou can also use nltest to get similar information:
> nltest /server:<DomainControllerName>/dsgetdc:<DomainName>
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.
