Thank you!, that was it. It wasn't my bug however :[, as the CreateFile is still failing, but the alloc_sd failures are gone (different sd's are used). *sigh*. Something is tromping on a static class member and invalidating the sd. Are sd's ever corrupted by system calls, or can one reuse an sd indefinately? Rob
