In 10 years plus of running a Windows-based DHCP I have not encountered such as this malfunction of my Windows 10 partially obtaining the DHCP lease. he machine obtained the IP but not the default gateway and DNS. The default gateway if the dhcp lease.
This started occurring more occasionally since I moved my DHCP from WinServer2012 R2 to a Firewall device running SF OS acting as a perimeter LAN/WAN
