When you �run the MQTrace Utility on Microsoft Windows Vista or Microsoft Windows Server 2008 systems, you may receive the following error: �

�Data Collector Set was not found�

�

The MQTrace Utility may fail to create a trace file in the default location of C:\Windows\debug resulting in the following error being displayed on-screen.

�

C:\Windows\Debug>mqtrace -query

mqtrace 1.4 - Manage MSMQ Release Bits Tracing.

Querying msmq trace session...

�

Error:

Data Collector Set was not found.

This issue may happen when you use the MQTrace utility and while tracing is started, the MSMQ service is stopped and restarted.

�

This is caused because the debug folder does not have the necessary permissions set to allow the program to create the log file.

�

Without the necessary permissions, the NetworkService account does not have the permission to control the tracing session.� The �-start� trace command fails as it needs to create the log file.�� Since the context is executed using NetworkService, the �-start� trace command fails without the necessary rights.

�

To work through this issue, modify the permissions to allow the log file to be created in the Debug folder.� To do this, follow these steps:

�

1.������ �Navigate to the C:\Windows\debug folder

2.������ Right-click on the Debug folder, and then click Properties.�

3.������ Under the �Security� tab, grant the NetworkService account �Modify� permissions on the folder.

�

Once permissions are granted that allow the NetworkService account to write in the C:\Windows\debug folder, the tracing is started when the MSMQ (Message Queueing) service starts.
