DHCP not Updateing DNS

I have a newer VDI environment.  Two DHCP servers (Win2008R2) are assigned to hand out IP's to Win7 clients.  

The scope properites are set to:
enable DNS Dynanically ... Always dynaically update DNS A and PTR records... Discard A and PTR recros when lease is deleted... Dynamically updated DNS An dn PTR records for clients that do not request.

Still my DNS records of my VDI are chronically inaccurate.

Ideas?

you must set credentials in DHCP server (IPV4 in DHCP Console) properties \ advanced tab, other wise this process will not work
Note that account must be standard domain user account with non expiring password
This will ensure that when DHCP lease will expires \ changes by any mean on DHCP server, it will update corresponding DNS records

Also ensure that secure dynamic update is enabled on domain dns forward lookup zone (domain.com) and all reverse lookup DNS zones, other wise process will fail

Add both of your DHCP servers to DNSUPDATEPROXY group on domain controller
If you added DHCP servers in dnsupdateproxy group, then run below command on dns server
dnscmd /config /OpenAclOnProxyUpdates 0

Find excellent article

Also set scavenging on any one DNS server properly so that it will delete stale records on regular basis
Also in scavenging set Refresh Interval more than no refresh interval so that DNS will entertain dynamic update queries more time

Check below article to set scavenging properly in relation with DHCP

Mahesh,

That first article was great.  This video helped me understand No-Refresh and Refresh Intervals.

Thanks!
