SYMPTOMS
You can use Microsoft BizTalk Server Orchestration Designer to implement schedule ports by using Microsoft Windows Scripting Component (.wsc) components. However, if you start an XLANG schedule that calls a .wsc file that uses the Microsoft Visual Basic Scripting Edition (VBScript) MsgBox function, the schedule may appear to have stopped responding.



CAUSE
This problem may occur if the application identity of the XLANG Scheduler COM+ application is not set to Interactive User.



RESOLUTION
Verify that the application identity of the XLANG Scheduler COM+ application is set to Interactive User.



STATUS
This behavior is by design.



MORE INFORMATION
When the application identity of the XLANG Scheduler COM+ application is set to something other than Interactive User, and you start an XLANG schedule that calls a .wsc file that uses the VBScript MsgBox function, the MsgBox function fires correctly. However, the resultant message box is not visible. When this problem occurs, you cannot click anything that is in the message box. Therefore, the script component cannot continue to run and the schedule appears to have stopped responding.
