Hi,
Is it possible to disable Remote Desktop Services RPC calls from remote machines?
I'm referring to the "Terminal Services Terminal Server Runtime Interface Protocol":
https://learn.microsoft.com/en-us/openspecs/windows_protocols/ms-tsts/1eb45af1-94f1-4c42-9e13-dd0a018646fd
I know that by blocking port 445 I can block these calls, but it will block all SMB communication.
Thanks,
Gabriel

Hi,
Why would you looking for method to disable RPC service?
Many system components are dependent on this service and as a result, some Windows procedures don't work if the Remote Procedure Call service is disabled.

Hi,
I didn't ask about disabling the RPC service, I asked specifically about the Remote Desktop Services RPC API. This API uses RPC over named pipes so I don't think it even uses the RPC service (I'm not 100% sure about that, but anyway I didn't refer to this specific service).
Thanks
Hi Gabriel
I added the tag Openspecs-Windows to your original post. One of engineers from Microsoft Open Specifications Support will be contacting you shortly.

Hi Gabriel:
Please ignore the reply from @Hung-Chun Yu above.
The purpose of @openspec-* tags is to support implementers using open specifications to develop interoperability solutions with Windows. The open specifications are found at https://learn.microsoft.com/en-us/openspecs/
Your question is about configuration and the tags that your original post had were correct. I have removed the openspecs-windows tag.
