Time:

User: Network services

Description: The application-specific permission settings do not grant Local Launch permission for the COM Server application with CLSID  to the user. This security permission can be modified using the Component Services administrative tool.



CAUSE
This problem may occur if either of the following conditions is true:
 * A program with the class ID (CLSID) that appears in the message tries to start the COM component by using the DCOM infrastructure. However, the user does not have the required permissions to start the COM component.
 * The Network Service account does not have the correct permissions.



RESOLUTION
Warning Serious problems might occur if you modify the registry incorrectly by using Registry Editor or by using another method. These problems might require that you reinstall your operating system. Microsoft cannot guarantee that these problems can be solved. Modify the registry at your own risk.

To resolve this problem, use one of the following methods, depending on the cause of the problem.

Grant the user permissions to start the COM component
Grant the user permissions to start the COM component. To do this, follow these steps:  Click Start, click Run, type regedit in the Open box, and then click OK. Locate and then click the following registry subkey:

Note In this subkey, &quot;CLSID value&quot; is a placeholder for the CLSID information that appears in the message. In the right pane, double-click AppID.

The Edit String dialog box appears. Leave this dialog box open and continue to the next step. Click Start, click Run, type dcomcnfg in the Open box, and then click OK.

If a Windows Security Alert message prompts you to keep blocking the Microsoft Management Console program, click to unblock the program. In Component Services, double-click Component Services, double-click Computers, double-click My Computer, and then click DCOM Config. In the details pane, locate the program by using the friendly name.

If the AppGUID identifier is listed instead of the friendly name, locate the program by using this identifier.</li> Right-click the program, and then click Properties.</li> Click the Security tab.</li> In the Launch and Activation Permissions area, click Customize, and then click Edit.</li> Click Add, type the user's account name, and then click OK.</li> While the user is selected, click to select the Allow check boxes for the following items: <ul> Local Launch</li> Remote Launch</li> Local Activation</li> Remote Activation</li></ul> </li> Click OK two times.</li> Quit Registry Editor.</li></ol>
