Hi T800,

Thanks for your post.

It is most likely that you are attempting to connect to a User ID, which is only accessible during an RDP session.
Once the RDP session is closed (user logged out), connections to the User ID can not be initiated until the user is signed in again.
I hope the articles help you.
