Hi

We have DHCP configured on Cisco Switches across company over 140 sites. DHCP is configured on local switch. Lease time configured is 8 hours. PCs login on the Windows 2012 R2 domain controller with DNS. Issue is that machine names are not updated in the DNS. Number of times entries in DNS are outdated. Even if we flush DNS, records are not updated. I just want to know if there is anything i can check at DHCP level to force DNS to update?

Regards,
