3.1.1.7.2.4 Resetting the pdcChangeLog
To reset the pdcChangeLog, set the array to have 0 elements, set SamCreationTime and BuiltinCreationTime to the current time and SamNT4ReplicationUSN and BuiltinNT4ReplicationUSN to one.
Resetting the pdcChangeLog has the effect of causing NT4 BDCs to perform a full sync.
