DHCP SERVER 2008 R2

-
Hi,
I am using Server 2008 R2 multihomed DHCP Server which is a IPv4 DHCP.
The problem is IPv6 DHCP is also servicing DHCP clients on my network which is giving out different range of my scope that is causing my DHCP clients not communicating my the server.
Event ID is 10020
I tried commands below but cannot solve I even untick IPv6 in the network adapters.
netsh winsock resetnetsh winsock reset catalog
ipconfig /flushdns
ipconfig /release
ipconfig /renew
netsh int ip stop
netsh int ip start
Thanks.

Hi,
Based on my research, DHCP can lease both IPv4 and IPv6 addresses. If IPv6 is not available, the DHCP service uses IPv4 only.
I recommend you run “sc queryex dhcp” at the command prompt to see if the DHCPv6 Server service is running or not.
