QuotaUserName and QuotaTarget Are Empty in GetNcQuotaReport

EdS

When running Get-NcQuotaReport we get numerous entries where the QuotaUserName and QuotaTarget are empty or blank.  How do we find out which files are contributing to these?

Get-NcQuotaReport -Volume Our_Volume | Select-Object diskused,QuotaUsers,Quotatarget | Where-Object {$_.QuotaUsers.QuotaUserName -like ''}

I believe these entries are reported for objects that are owned by a SID that no longer exists in Active Directory so that is why the two fields are blank.
