Currently we have PRTG running in our server room, where is away from where Amazon cloud. We have some Windows servers (EC2) running in west California region.
I tried to add an Amazon windows server as device in PRTG. When I placed a sensor to the server, it showed an error message, which is : "Connection could not be established (Port Error 135: RPC Server not accessible. - Host: 220.127.116.11, User: administrator, Password: **, Domain: ntlmdomain:18.104.22.168) (code: PE015) "
The user and password is what I use to connect to remote desktop.
How can I monitor an Amazon cloud windows server locally? I don't want to install remote agent on the cloud server.
