The machine-default permission settings do not grant Local Activation permission for the COM Server application with CLSID
{BC866CF2-5486-41F7-B46B-9AA49CF3EBB1}
to the user NT AUTHORITY\NETWORK SERVICE SID (S-1-5-20). This security permission can be modified using the Component Services administrative tool.
