DNSCMD (as referenced in my article in SSWUG.org)

By Johan van Soest.
Published  :  2014-01-30.

Domain Name Server (DNS) mutations can be performed by scripts using the following command line commands (Windows 2000 or better) :
  • DNSCMD /recordadd
  • DNSCMD /recorddelete

Examples

Adding DNS records
Adding a new DNS record to access the server named TestServer at IP-Address 10.1.133.45 with the DNS server nlaaldns1:
dnscmd nlaaldns1.van_soest.it /recordadd van_soest.it TestServer A 10.1.133.45
Adding the Alias FileServer pointing to the recently created TestServer
dnscmd nlaaldns1.van_soest.it /recordadd van_soest.it FileServer CNAME TestServer.van_soest.it
Testing the correct configuration with the ping command: 
c:>ping FileServer -4

Pinging TestServer.van_soest.it [10.1.133.45] with 32 bytes of data:
Reply from 10.1.133.45: bytes=32 time=21ms TTL=126
Reply from 10.1.133.45: bytes=32 time=21ms TTL=126
Reply from 10.1.133.45: bytes=32 time=22ms TTL=126
Reply from 10.1.133.45: bytes=32 time=22ms TTL=126

Ping statistics for 10.1.133.45:
    Packets: Sent = 4, Received = 4, Lost = 0 (0% loss),
Approximate round trip times in milli-seconds:
    Minimum = 21ms, Maximum = 22ms, Average = 21ms
Notice the ping request shows the original TestServer.
Removing DNS records
Removing the Alias and Host DNS records without asking for confirmation (use in batches):
dnscmd nlaaldns1.van_soest.it /recorddelete van_soest.it FileServer CNAME 10.1.133.45 /f
dnscmd nlaaldns1.van_soest.it /recorddelete van_soest.it TestServer A 10.1.133.45 /f

Warning: A Windows domain name can not contain an underscore "_" according to these standards. The underscore is used in these examples as a spam counter measure.
