We have 2 Server 2008 DNS servers that are pointing to each other for DNS. There are random records that are getting deleted or really assuming here that they are getting savaged. This leads me to believe that netlogon isn't refreshing the DNS records.
The A records are static and dynamic.
Zone is set for nonsecure and secure.
Scavenging is set to 7 days
Refresh interval is set to 1 hour.
These DNS/WINS servers are DC's.
Hope I didn't leave anything out.
