Hi Kostja,
The following group policies should be disabled on the remote computer:
* Always prompt client for password upon connection
* Prompt for credentials on the client computer (on Windows Vista and later)
If the remote computer belongs to a domain, these policies must also be disabled on the domain controller.
And the following group policy is enabled on it and the security layer is set to Negotiate.
* Require use of specific security layer for remote (RDP) connections​
For instructions, see Configure Group Policies [https://support.smartbear.com/viewarticle/82794/#GPO].
