When you try to log on using the Terminal Services client, you may receive the following error message:
Logon Message: You do not have access to logon to this session.
Terminal Services has a default connection security setting allows only administrators to log on. If the security attributes on a specified connection have not been set, the connection inherits these default security settings. For additional information, please see the following
article in the Microsoft Knowledge Base:
Default Connection Changes Are No longer Applied
If the default connection security settings do not meet your needs, you can set custom security attributes.
To set custom Terminal Services connection permissions:
- Click Start, point to Programs, point to Administrative Tools, and then click Terminal Services Configuration.
- Open the Connections folder.
- Right-click the connection (RDP-TCP), and then click Properties.
- On the Permissions tab, add the group(s) that needs access to this connection.
- Click OK.
This behavior is by design.
