Peter[Pan],
On my W2K+SP4+Rollup update your trick doesn't work. I can't download your example (i haven't permissions for this) and i've wrote my own. After ZwQueryObject structure ObjectAllTypesInformation fills with 17h OBJECT_TYPE_INFORMATION structures. But there is no "DebugObject" name within. Did you mean "OBJECT_TYPE_INFORMATION.name" member ?
