Enabling DCOM

WMI uses DCOM to communicate with monitored target computers. Therefore, for Application Performance Monitor to use WMI, you must have DCOM enabled and properly configured. Follow these steps to enable DCOM permissions for your Application Performance Monitor credentials:

1. Log on to the target host as an administrator.

2. Navigate to Start > Control Panel > Administrative Tools > Component Services. (Only the Classic view of the Control Panel has this navigation path). You can also launch this console by double-clicking comexp.msc in the /windows/system32 directory.

3. Expand Component Services > Computers.

4. Right-click My Computer, and then select Properties.

5. Select the COM Security tab, and then click Edit Limits in the Access Permissions grouping.

6. Ensure the user account collecting WMI statistics has Local Access and Remote Access, and then click OK.

7. Click Edit Default, and then confirm the user account collecting WMI statistics has Local Access and Remote Access, then click OK.

8. Click Edit Limits in the Launch and Activation Permissions grouping.

9. Ensure the user account collecting WMI statistics has Local Launch, Remote Launch, Local Activation, and Remote Activation enabled, and then click OK.

10. Click Edit Default, and then ensure the user account collecting WMI statistics has Local Launch, Remote Launch, Local Activation, and Remote Activation enabled.

11. Click OK.
