Hi,

1. Yes
2. Disabling api hooking made it work again with external settings, thx

Can you tell me the difference between external and internal RDP? wich is the most stable?

Hello,

Are you referring to the distinction between "external" and "undocked" sessions?

• "Undocked" refers to sessions that RDM initiates but displays in a separate window.
• "External" implies that another application is responsible for launching the session.

Best regards,

We have also experienced this since KB5030219. Will there be a more permanent solution than disabling API Hooking?

Hello,

Our development team is actively working on resolving the issue you've reported. We will keep you updated on our progress.

Hello,

• "Undocked" refers to sessions that RDM initiates but displays in a separate window.
• "External" implies that another application is responsible for launching the session.

Best regards,

I meant the difference between the external application and the "internal" (undocked or docked) RDP application.
What's the key difference?

Hello,

I apologize for the confusion.

To clarify, there is no functional difference between the "undocked" and "docked" modes. There is no version that is more stable than the other.

Best regards,
