Comments
|
Do any dnscmd command on a remote system
|
dnscmd servername command
|
dnscmd main.bigfirm.com /zoneprint bigfirm.com
|
|
Create a primary zone
|
dnscmd /zoneadd zonename /primary
|
dnscmd /zoneadd bigfirm.com /primary
|
|
Create a secondary zone
|
dnscmd /zoneadd zonename /secondary master IP address
|
dnscmd /zoneadd bigfirm.com /secondary 192.168.1.1
|
|
Host a zone on a server based on an existing (perhaps restored) zone file
|
dnscmd /zoneadd zonename /primary /file filename /load
|
dnscmd /zoneadd bigfirm.com /primary /file bigfirm.com.dns /load
|
|
Delete a zone from a server
|
dnscmd /zonedelete zonename [/f]
|
dnscmd /zonedelete bigfirm.com /f
|
(without the /f, dnscmd asks you if you really want to delete the zone)
|
Show all of the zones on a DNS server
|
dnscmd /enumzones
|
dnscmd /enumzones
|
|
Dump (almost) all of the records in a zone
|
dnscmd /zoneprint zonename
|
dnscmd /zoneprint bigfirm.com
|
Doesn't show glue records.
|
Add an A record to a zone
|
dnscmd /recordadd zonename hostname A ipaddress
|
dnscmd /recordadd bigfirm.com mypc A 192.168.1.33
|
|
Add an NS record to a zone
|
dnscmd /recordadd zonename @ NS servername
|
dnscmd /recordadd bigfirm.com @ dns3.bigfirm.com
|
|
Delegate a new child domain, naming its first DNS server
|
dnscmd /recordadd zonename childname NS dnsservername
|
dnscmd /recordadd bigfirm.com test NS main.bigfirm.com
|
This would create the "test.bigfirm.com" DNS child domain unter the bigfirm.com DNS domain
|
Add an MX record to a zone
|
dnscmd /recordadd zonename @ MX priority servername
|
dnscmd /recordadd bigfirm.com @ MX 10 mail.bigfirm.com
|
|
Add a PTR record to a reverse lookup zone
|
dnscmd /recordadd zonename lowIP PTR FQDN
|
dnscmd /recordadd 1.168.192.in-addr.arpa 3 PTR pc1.bigfirm.com
|
This is the PTR record for a system with IP address 192.168.1.3
|
Modify a zone's SOA record
|
dnscmd /recordadd zonename @ SOA primaryDNSservername responsibleemailipaddress serialnumber refreshinterval retryinterval expireinterval defaultTTL
|
dnscmd /recordadd bigfirm.com @ SOA winserver.bigfirm.com mark.bigfirm.com 41 1800 60 2592000 7200
|
Ignores the serial number if it's not greater than the current serial number
|
Delete a resource record
|
dnscmd /recorddelete zonename recordinfo [/f]
|
dnscmd /recorddelete bigfirm.com @ NS main.bigfirm.com /f
|
Again, "/f" means "don't annoy me with a confirmation request, just do it."
|
Create a resource record and incorporate a nonstandard TTL
|
dnscmd /recordadd zonename leftmostpartofrecord TTL restofrecord
|
dnscmd /recordadd bigfirm.com pc34 3200 A 192.168.1.4
|
|
Reload a zone from its zone file in \windows\system32\dns
|
dnscmd /zonereload zonename
|
dnscmd /zonereload bigfirm.com
|
Really only useful on primary DNS servers
|
Force DNS server to flush DNS data to zone file
|
dnscmd /zonewriteback zonename
|
dnscmd /zonewriteback bigfirm.com
|
|
Tell a primary whom to allow zone transfers to
|
dnscmd /zoneresetsecondaries zonename /nonsecure|securens
|
dnscmd /zoneresetsecondaries bigfirm.com /nonsecure
|
That example says to allow anyone who asks to get a zone transfer
|
Enable/disable DNS NOTIFY
|
dnscmd /zoneresetsecondaries zonename /notify|/nonotify
|
dnscmd /zoneresetsecondaries bigfirm.com /nonotify
|
Example disables DNS notification, which is contrary to the default settings.
|
Tell a secondary DNS server to request any updates from the primary
|
dnscmd /zonerefresh zonename
|
dnscmd /zonerefresh bigfirm.com
|
|
Enable or disable dynamic DNS on a zone
|
dnscmd /config zonename /allowupdate 1|0
|
1 enables, 0 disables, 0 is default
|
|
Stop the DNS service
|
Either net stop dns or sc stop dns
|
|
(No dnscmd command for this)
|
Start the DNS service
|
Either net start dns or sc start dns
|
|
(No dnscmd command for this)
|
Install the DNS service on a 2008 full install system
|
servermanagercmd -install dns
|
|
|
Install the DNS service on a 2008 Server Core system
|
ocsetup DNS-Server-Core-Role
|
|
Case matters -- ocsetup dns-server-core-role would fail
|
Uninstall the DNS service on a 2008 Server full install system
|
servermanagercmd -remove dns
|
|
|
Uninstall the DNS service on a 2008 Server Core system
|
ocsetup /uninstall DNS-Server-Core-Role
