Recreate DNS Hosts From Export File Into a Microsoft DNS Server
The following script was created to add hosts, from a list of exported hosts and IPs originally from a unrelated DNS server’s zone, into the specified Microsoft DNS server’s DNS zone.
The basic usage of the script is:
CScript AddDNSHost.vbs /DNSServer:DNSServer /DNSZone:DNSZone /HostName:HostName /HostIP:HostIP
And an example:
AddDNSHost.vbs /DNSServer:192.168.0.1 /DNSZone:DNSZone.local /HostName:MyComputer /HostIP:192.168.1.123
A very simple way of constructing multiple commands can be achieved with practically any speadsheet application where column A holds the list of host names, column B holds their respected IP addresses and column C the following command (starting from row 1):
=”AddDNSHost.vbs /DNSServer:192.168.0.1 /DNSZone:DNSZone.local /HostName:” & A1 & ” /HostIP:” & B1
The above command can be copied once for each row.
The resulting constructed command can then be directly pasted into a command prompt
