We’re AD 2008 R2 (2 sites, 2 DCs each site) and if I look in DNS under the forward lookup zone for ourcompany.com, for some I can see the same IP assigned for up to 3 hosts.
If I ping-A the 3 host it comes back with same IP for all 3 hosts. If I ping-a the IP address it comes back with the hostname for the host with the latest s timestamp on the record. I guess it’s something to do with DHCP?
We don’t seem to be having any problems but I don’t imagine it’s good!
2 questions please:
How do I fix with no disruption to PCs?
How is it I ping 3 hostnames and they return the same IP, I guess they have other IPs but I can’t see these in DNS.
