APPLIES TO


 * Microsoft COM+ 2.0 Standard Edition

SYMPTOMS
Microsoft COM+ events may be raised incorrectly when the following conditions are true:
 * You have multiple Library COM+ applications that are loaded in a single process.
 * More than one of the COM+ applications is configured for transient events.

COM+ events may be raised on all the listed Library COM+ applications. Alternatively, no COM+ events may by raised.

This behavior occurs only for Library applications in COM+. You can have multiple Server applications that are subscribed to COM+ events.



CAUSE
This behavior occurs because of a limitation in COM+.



WORKAROUND
To work around this behavior, configure the COM+ applications as Server applications instead of as Library applications. When you configure the COM+ applications as Server applications, each application is hosted in a different process.

To configure the COM+ applications as Server applications, follow these steps:
 * 1) Open Component Services.
 * 2) Expand Component Services, expand Computers, expand My Computer, and then click COM+ Applications.
 * 3) Right-click the COM+ application that you want to modify, and then click Properties.
 * 4) Click the Activation tab, select the Server application option, and then click OK.



STATUS
This behavior is by design.
