|---|
/maxnegativecachettl [<seconds>] |
Specifies how many seconds (0x1-0xFFFFFFFF) an entry that records a negative answer to a query remains stored in the DNS cache. The default setting is 0x384 (900 seconds). |
/namecheckflag [0|1|2|3] |
Specifies which character standard is used when checking DNS names. Accepts the values:0 - Uses ANSI characters that comply with Internet Engineering Task force (IETF) Request for Comments (Rfcs).1 - Uses ANSI characters that do not necessarily comply with IETF Rfcs.2 - Uses multibyte UCS Transformation format 8 (UTF-8) characters. This is the default setting.3 - Uses all characters. |
/norecursion [0|1] |
Determines whether a DNS server performs recursive name resolution. Accepts the values:0 - The DNS server performs recursive name resolution if it is requested in a query. This is the default setting.1 - The DNS server does not perform recursive name resolution. |
/notcp |
This parameter is obsolete, and it has no effect in current versions of Windows Server. |
/recursionretry [<seconds>] |
Determines the number of seconds (0x1-0xFFFFFFFF) that a DNS server waits before again trying to contact a remote server. The default setting is 0x3 (three seconds). This value should be increased when recursion occurs over a slow wide area network (WAN) link. |
/recursiontimeout [<seconds>] |
Determines the number of seconds (0x1-0xFFFFFFFF) that a DNS server waits before discontinuing attempts to contact a remote server. The settings range from 0x1 through 0xFFFFFFFF. The default setting is 0xF (15 seconds). This value should be increased when recursion occurs over a slow WAN link. |
/roundrobin [0|1] |
Determines the order in which host records are returned when a server has multiple host records for the same name. Accepts the values:0 - The DNS server does not use round robin. Instead, it returns the first record to every query.1 - The DNS server rotates among the records that it returns from the top to the bottom of the list of matching records. This is the default setting. |
/rpcprotocol [0x0|0x1|0x2|0x4|0xFFFFFFFF] |
Specifies the protocol that remote procedure call (RPC) uses when it makes a connection from the DNS server. Accepts the values:0x0 - Disables RPC for DNS.0x01 - Uses TCP/IP0x2 - Uses named pipes.0x4 - Uses local procedure call (LPC).0xFFFFFFFF - All protocols. This is the default setting. |
/scavenginginterval [<hours>] |
Determines whether the scavenging feature for the DNS server is enabled, and sets the number of hours (0x0-0xFFFFFFFF) between scavenging cycles. The default setting is 0x0, which disables scavenging for the DNS server. A setting greater than 0x0 enables scavenging for the server and sets the number of hours between scavenging cycles. |
/secureresponses [0|1] |
Determines whether DNS filters records that are saved in a cache. Accepts the values:0 - Saves all responses to name queries to a cache. This is the default setting.1 - Saves only the records that belong to the same DNS subtree to a cache. |
/sendport [<port>] |
Specifies the port number (0x0-0xFFFFFFFF) that DNS uses to send recursive queries to other DNS servers. The default setting is 0x0, which means that the port number is selected randomly. |
/serverlevelplugindll[<dllpath>] |
Specifies the path of a custom plug-in. When Dllpath specifies the fully qualified path name of a valid DNS server plug-in, the DNS server calls functions in the plug-in to resolve name queries that are outside the scope of all locally hosted zones. If a queried name is out of the scope of the plug-in, the DNS server performs name resolution using forwarding or recursion, as configured. If Dllpath is not specified, the DNS server ceases to use a custom plug-in if a custom plug-in was previously configured. |
/strictfileparsing [0|1] |
Determines a DNS server's behavior when it encounters an erroneous record while loading a zone. Accepts the values:0 - The DNS server continues to load the zone even if the server encounters an erroneous record. The error is recorded in the DNS log. This is the default setting.1 - The DNS server stops loading the zone, and it records the error in the DNS log. |
/updateoptions <RecordValue> |
Prohibits dynamic updates of specified types of records. If you want more than one record type to be prohibited in the log, use hexadecimal addition to add the values, and then enter the sum. Accepts the values:0x0 - Doesn't restrict any record types.0x1 - Excludes start of authority (SOA) resource records.0x2 - Excludes name server (NS) resource records.0x4 - Excludes delegation of name server (NS) resource records.0x8 - Excludes server host records.0x100 - During secure dynamic update, excludes start of authority (SOA) resource records.0x200 - During secure dynamic update, excludes root name server (NS) resource records.0x30F - During standard dynamic update, excludes name server (NS) resource records, start of authority (SOA) resource records, and server host records. During secure dynamic update, excludes root name server (NS) resource records and start of authority (SOA) resource records. Allows delegations and server host updates.0x400 - During secure dynamic update, excludes delegation name server (NS) resource records.0x800 - During secure dynamic update, excludes server host records.0x1000000 - Excludes delegation signer (DS) records.0x80000000 - Disables DNS dynamic update. |
/writeauthorityns [0|1] |
Determines when the DNS server writes name server (NS) resource records in the Authority section of a response. Accepts the values:0 - Writes name server (NS) resource records in the Authority section of referrals only. This setting complies with Rfc 1034, Domain names concepts and facilities, and with Rfc 2181, Clarifications to the DNS Specification. This is the default setting.1 - Writes name server (NS) resource records in the Authority section of all successful authoritative responses. |
/xfrconnecttimeout [<seconds>] |
Determines the number of seconds (0x0-0xFFFFFFFF) a primary DNS server waits for a transfer response from its secondary server. The default value is 0x1E (30 seconds). After the time-out value expires, the connection is terminated. |
