2.2.10.2.14 DNSSRV_DS_STATS
The DNSSRV_DS_STATS structure has DNS server statistics related to directory server processing. The UpdateLists member through DsWriteType member refer to statistical values, when the server is propagating changes from the in-memory database to the directory server.
This structure MUST be formatted as follows:

FailedLdapAdd (4 bytes): The number of times the server failed to add entries to the directory server.
PollingPassesWithDsErrors (4 bytes): The number of times the server hit failure while polling zones in the directory server. This field SHOULD<75> be present. A client can tell whether the field is present based on the size of the buffer holding this structure.
LdapReconnects (4 bytes): The number of times the server attempted to reconnect to the directory server. This field MUST be present if and only if PollingPassesWithDsErrors is present. A client can tell whether the field is present based on the size of the buffer holding this structure.
DsWriteType (160 bytes): An array of 32-bit unsigned integers that keeps track of update requests for different DNS record types as specified DNS_RECORD_TYPE (section 2.2.2.1.1). There are a total of 40 entries each corresponding to the number of received update requests for different record types in the order specified in DNS_RECORD_TYPE (section 2.2.2.1.1), starting from DNS_TYPE_ZERO to DNS_TYPE_DNAME.
