The Login VSI management console is stuck on RdpSuccessful at one of the last steps of the start test wizard. You may see RDP windows with just a background. No icons or desktop elements.
Starting with Login VSI 4.1.25 the VSI Management console has changed the way it performs the so called 'Launcher Workflow'.
The workflow has multiple phases; Phase 1 logs off existing users from the launcher(s). Phase 2 initiates an RDP connection to the launcher. Currently phase 2, initiating an RDP connection, happens too quickly. The launcher isn't ready to accept connections yet.
Eventually the connection is dropped. Running quser /server:LauncherHostName will show RDP session in a down state.
A hotfix is available that introduces a static 10 second delay between phase 1 and phase 2. This hotfix can be found here.
Apply the hotfix by replacing \\server\vsishare\_VSI_ManagementConsole\Login VSI Management Console.exe with the version from the zip file.
