Windows 2008 R2 DNS Cache Minimum TTL
Posted on 2010-01-05
I have a HP DL360 G5 running Windows 2008 R2 operating system with DNS. It's the DNS that comes with the OS. What I want is to change the minimum time that an entry can exist in the cache. I have found the maxcachettl referenced in many places, including Microsoft support site and Technet. I have had zero luck finding anything referencing mincachettl, or similar, settings. I want to make it such that any cache entry remains for at least X time regardless of the TTL specified in the response. If they give the option for maxcachettl, surely there's a mincachettl and I'm just missing it.
