ms-dns is bind sometimes mostly. someone not me created a whole bunch of reverse subnets weirdly. 10.x.x.x Subnet with the subdomains 123 and subdomains 11, 12, 13, 14, 15. pretty in a gui. but, hey. however, when I attempt to create a PTR via dnscmd, a la: dnscmd /RecordAdd 123.10.in-addr.arpa 1.11 PTR system001.elevennetwork.local i get unhappy zone not existing and other silliness. dnscmd /enumzones i see, among others: 10.in-addr.arpa oh, i see. nice. okay. dnscmd /RecordAdd 1.11.128 PTR system001.elevennetwork.local works! but i a zillion of these addresses. i simply cannot do this by hand. i create a file with all of my tasty records however i do as such: 2.11.123 system002.elevennetwork.local 3.11.123 system003.elevennetwork.local 24.12.123 system024.twelvenetwork.local ... you get the hint ... for /f "tokens=1-2" %i in (tastyrecords) do dnscmd %LOGONSERVER% /RecordAdd 10.in-addr.arpa %i PTR %j and it works.
