We’re gonna solve the DHCP server authorization issue in this post. Error code looks like below:
“The authorization of DHCP Server failed with Error Code: 20070. The DHCP service couldn’t contact Active Directory.”
This is possibly due to user permissions on AD. Ensure you input Domain Administrator (DA) Credentials in the DHCP Commit dialog box, instead of proceeding with logged in account. There are chances that though you logged into DC using some user credentials, it doesn’t necessarily mean you are DA/EA. It could just be an account Admin locally, but not on Domain/forest. Check the DA user in ADUC and ensure you input those credentials to solve this.
Other things you should try if the credentials are DA is, ensure AD services are up and running. Check launching ADUC, Try Restarting DHCP Server services, Try re-installing DHCP from server manager. If you still encounter any issues, please message here, so we can further look into it to get it resolved.
Cheers!

Thanks for your assistance. DHCP has been authorised after switching to DA ..It was logged in with a local account.
