The Mshta.exe process does not close when you exit an HTML application that is published on a Terminal Server that is running Windows Server 2003

Support for Windows Server 2003 ended on July 14, 2015

Microsoft ended support for Windows Server 2003 on July 14, 2015. This change has affected your software updates and security options. Learn what this means for you and how to stay protected.

From a remote desktop session, you exit a Microsoft HTML application (HTA) that is published as a program on a Terminal Server. The Terminal Server is running Microsoft Windows Server 2003. After you exit the HTA program, it may appear to close. However, the Mshta.exe process that runs the HTA program does not close, although the process stops responding.
This problem occurs because the Mshtml.dll file does not receive the correct Windows message to close. This problem occurs when an HTA is run as a published program in a Terminal Services environment.
