Thx. I was reviewing ZwQueryQuotaInformationFile(), which this call relies on, and surmised that STATUS_BUFFER_TOO_SMALL is returned only if a buffer was supplied that was too small for a single entry. Thanks for confirming. I'll review the rest and file a report against [MS-SMB].

I've seen STATUS_BUFFER_TOO_SMALL only if MaxDataCount is not enough for a single quota record. Otherwise it's a series of OK's that end with a STATUS_NO_MORE_ENTRIES. BTW, this is the documented [MS-SMB2] behavior.
Attached pls find a packet trace. MaxDataCount has been purposefully made small here to show a series of requests.
