If I may speak to this issue...
The duke set up a home network and as such does not have access to M$ Premier Support so it is unlikely this issue will ever make its way to M$. Unless this is a case of misconfiguration of the DC, it exposes a potential vulnerability.
There has not been extensive testing. The problem manifests itself on only the one DC and only when logging on from one particular WKSTA. Then too, it only manifests when the network is queried by functions like InGroup().
If you reread the thread, you will see that we tested different versions of KiX. The duke said he is going to get off the bleading edge and fall back to Windows 2000.
