Lately our team has received a lot requests to add new DNS records for testing our web server. I was getting tired of add a record in DNS manually for those Host headers in IIS. Here is what I come up with.
$A = [wmiclass]"\\xyz\root\MicrosoftDNS:MicrosoftDNS_AType"
$DNSServer = "xyz.R-test.com"
$Zone = "R-Test.com"
$class = 1
$TTL = 3600
$IPAddress = "192.168.1.88"
$Sites = Get-content WebSites.txt
Foreach ($Site in $Sites)
{
$A.CreateInstanceFromPropertyData($DNSserver, $zone, $Site, $class, $ttl, $IPAddress)
}
The WebSites.txt is something look like this:
whatever1.R-test.com
whatever2.R-test.com
whatever3.R-test.com
whatever4.R-test.com
...
If whateverx already has a DNS A record, you will get something like this:
Exception calling "CreateInstanceFromPropertyData" : "Generic failure "
At C:\Documents and Settings\Administrator.RELATED-TEST\My Documents\AddDNSARecords.ps1:13 cha
+ $A.CreateInstanceFromPropertyData( <<<< $DNSserver, $zone,$Site, $class, $ttl, $IPAddress)
