SYMPTOMS
Application Center COM+ deployments do not update or remove existing COM+ applications on the target server or servers.



CAUSE
Application Center relies on Component Services to add, remove, and update COM+ applications. COM+ applications that are in use by other processes prevent Component Services from updating or removing the target COM+ application until all processes and applications that are using the COM+ application have been shut down. Some applications and processes that may be using COM+ applications are Microsoft Windows NT services (such as the IIS Admin Service), Win32 applications (such as a Microsoft Visual Basic 6.0 application), and other COM+ applications.



RESOLUTION
Shut down all processes and applications that you suspect are using the target COM+ applications. If you still cannot remove or update the COM+ application, you can disable any Windows NT services or applications on the target server that you suspect are using the COM+ application, and then restart the server.



STATUS
This behavior is by design.



Steps to Reproduce the Behavior

 * 1) Deploy a COM+ application (ComApp1) from the source server (Web1) to another Application Center server (Web2).
 * 2) Modify ComApp1 on Web1 by adding or removing a component or by changing one of its settings in Component Services.
 * 3) While ComApp1 on Web2 is in use by another application (such as a Win32 application), deploy ComApp1 from Web1 to Web2.
