IHS stops after Windows logout

IBM Domino 9.0.1 is configured to run IHS. Domino is set to start as Windows service. It starts IHS without any issues. However, if I login to Windows and then logout, IHS stops, but Domino HTTP stays up. After restarting Domino HTTP task, IHS starts normally, but then again shuts down after Windows logout. I can restart Domino HTTP task via Admin client after logout, and IHS will work fine. But only until interactive Windows logout. I tried to reinstall IBM Domino 9.0.1 after completely uninstalling it. Same issue. OS is Windows 2003SP2, 32bit.

Subject: IHS software limitation

IBM confirmed the issue. No fix is currently available. Possible fix in the future. Bummer.
