In our small company, we have VMs on ESXI. One of them being the Domain Controller.
We have Avaya phones with their IP being (192.168.0.11
), our IP range is mutually exclusive from Avaya.
Our Desktops are picking that DNS and Default gateway up rather than what the DHCP gives. This only started occurring last week. Restarted the DHCP server and didn't fix it either. It's only affecting some PCs.
ipconfig /renew
and /reset
gives it the DNS and default gateway from DHCP. But is then reset to the Avaya DNS after restart. For the mean time, I have manually given the default gateway and DNS for those problematic computers (instead of automatic) and everything works fine, but still want to resolve it.
