DNS / DHCP - Since the holidays - DNS all wrong !!! Scavenging not working
Can anyone please help. I thought we had DNS working perfectly, but after the 6 weeks holiday i have noticed that around 40% of the computer in DNS have the incorrect IP.
I have followed several guides and noticed that our outdated timestamped DNS entries arent being scavenged. I have set scavenging in the 3 places suggested:
The DNS server - "Automatic Scavenging of stale records" enabled and set to 7 days
The Zone - "Scavenge Stale Resource records" enabled, No-Refresh interval set to 3 days. Refresh interval set to 3 days.
DHCP has the Lease Duration set to 3 days.
I have DNS records with the dates of May 2011. I have tried to tell DNS to scavenge records now but i get the 2052 error.
I can only see one 2051 log of scavenging report from back in Jan 2011 and nothing has been touched since then.?
Can anyone please advice their working dates and times or suggest a solution for me?
Thanks in advance!
