We need to resolve local names and, because of that, we installed a DNS server on a Red Hat server. Our workstations are running Windows 7. The IP v4 address is get from a DHCP server that maintains the address static for each MAC address. IP v6 is turned off.
The DHCP server provides 2 DNS servers. The primary is the local server and de secondary is a public DNS server like 8.8.8.8.
Sometimes one or other client cannot access the local hosts. Not the same client and not at the same time.
With the network monitor we realized that, sometimes, windows 7 uses the secondary DNS instead of the primary. The secondary, obviously, fails to resolve the internal names.
Has anyone seen that before?
Why is that happening?
Thanks for any help
