DNS 101 - why are there entries from 2012 for machines on the LAN sbs 2011
Posted on 2014-01-20
Sorry, this is likely a real basic question but....
why when I look at the forward lookup zones under the ourdomain.local folder, there's host(a) records for machines LONG gone. it has timestamps for some of these from september 2012! Several machines have the same IP addresses - the machine that had it long ago and now the current machine.
I right click and choose all tasks, reload - no change
on the server name, I right click and choose scavange stale resource records - no change
AH!!! under server aging / scavenging, the scavanage stale records is not checked. I check that. Leave the 2 intervals (no refresh and refresh) at 7 days? It's a 15 user network. lower it to hours?
will that solve the problem? is that scavange checkbox unchecked by default?
what else can I change from the default that woudl make sense for better operations?
