After a unexpected shutdown of my computer I found this message in the
event viewer:

###
Anmeldversuch von: MICROSOFT_AUTHENTICATION_PACKAGE_V1_0
Anmeldekonto: norbert
Arbeitsstation:
Fehlercode: 0xC000006A
###

Does somebody know what this MICROSOFT_AUTHENTICATION_PACKAGE, that
tried to login, is and what is does ?

Thanks in advance
