2 DNS records for server causing problems

slselwyn used Ask the Experts™

In DNS forward zone XXXX is shown as both and There are connection issues from workstations sometimes solved by a server reboot or combined server & workstation reboot. When the problem exists ping XXXX from a workstation resolves as If I then delete from DNS and flushdns on the workstation it then correctly resolves as and everything works. Changes to the workstations host file also solves the problem. The issue is that keeps on returning as a DNS record. Why does it so this, should it be there and if not how do I stop this from coming back and creating issues on workstations without host file changes?

Check the setting on both/each card.
