yes, you may remember a similar post for enumerating dns ptr records with dnscmd. this is basically the same thing. except in this scenario, we're going to use findstr to help locate the records we want.
dnscmd myDnsServer /enumrecords myZone.myRoot.com . /continue | findstr crap crap 3600 A 192.168.1.220 myCrap 3600 A 192.168.1.221
well, look at that. that was easy. we enumerate all records in any given zone, then specify the /continue switch to search all records. the "." will tell it to pull back everything... and piping through findstr looks for any record with the word "crap" in it.
you can take it one step further and search all zones. check out the following example:
for /f %a in ('dnscmd myDnsServer /enumzones ^| findstr /i primary') do dnscmd myDnsServer /enumrecords %a . /continue | findstr /i crap crap 3600 A 192.168.1.220 crap2 [Aging:3569875] 1200 A 192.168.1.143 crap3 [Aging:3569899] 1200 A 192.168.1.142 crap4 [Aging:3569751] 1200 A 192.168.1.136 myCrap 3600 A 192.168.1.221
