Yosemite can't copy our DNS backups into a test server because it has a different name. That's quality program design right there.

So here's a helpful set of three commands that does exactly that:

-------

gwmi -namespace root\microsoftdns -class microsoftdns_zone | % { dnscmd /ZoneDelete $_.Name /f }

xcopy \\backup\dns\*.dns C:\WINDOWS\system32\dns\

gci C:\windows\system32\dns\* -include *.dns -exclude cache.dns | % { dnscmd /ZoneAdd $($_.Name.ToString().TrimEnd('.dns')) /Primary /file $_.Name /load }

-------

I can see how something that useful and simple would get left out of a backup application. I mean, who ever needs to test things using a copy of your production config?
