SYMPTOMS
When you click the SMS_NT_Logon_Discovery_Agent thread in Systems Management Server (SMS) Service Manager to query for its status, you may receive the following error message or one similar to it:

Error communicating with component



CAUSE
If Windows Networking Logon Client Installation is enabled but Windows Networking Logon Discovery is not enabled, the Microsoft Windows NT Domain controllers do not get the SMS_NT_Logon_Discovery_Agent installed. This agent appears in the SMS Service Manager tool, but when you query this agent, you receive the error message listed earlier in this article. It is by design behavior that the SMS_NT_Logon_Discovery_Agent (which runs as a service on domain controllers) would not be installed, and so would not be able to respond to a query request.



RESOLUTION
To verify the agent is not installed on the domain controllers, you can use the Windows NT Server Manager to connect to that server, or if you are at the console of a domain controller, use the Services tool in Control Panel to search for the SMS_NT_Logon_Discovery_Agent. Note that it should not be there.

If Windows Networking Logon Discovery is enabled, the domain controllers should receive the SMS_NT_Logon_Discovery_Agent service, and query requests within the SMS Service Manager tool should be successful in displaying a started or stopped status.
