David:

As you are aware, 1.5.65 will not work properly with cross-realm
Kerberos logons on Windows 7.  This wasn't fixed until 1.5.74.

However, if mpnotify.exe is never executed the network provider
is never called.  Therefore, the problem is unlikely to be related
to either afslogon.dll or kfwlogon.dll.  Use Sysinternals procdump
to capture a dump file with heap for winlogon.exe and ask Microsoft
Support to analyze it.
