The application-specific permission settings do not grant Local Activation permission for the COM Server application with CLSID
{61738644-F196-11D0-9953-00C04FD919C1}
to the user LAB\LAB_Admin_DB SID (S-1-5-21-1061890561-1051542271-3984552843-1157). This security permission can be modified using the Component Services administrative tool.
