Folks, I have a Juniper EX4200 DHCP server with Microsoft DNS server 2008, my problem is that since I installed the juniper DHCP server the reverse lookup zone on the microsoft DNS server stopped getting updated.
So please select also “Store the zone in Active Directory”. In a pure Windows Server DNS environment you should select “Allow only secure dynamic updates” otherwise you should select “Do not allow dynamic updates”.
In our case we select “Primary zone” and we want to store the information in Active Directory. Now you have to set Dynamic Update for DNS entry’s.
Hi, I am having DC on which DHCP and DNS is configured , the issue is PTR records are not getting created in the one of the revese lookup zone . Especially considering you are in one zone and ad intergrated.
When if i am creating the HOST A record MANUALLY then PTR record gets created for the associated HOST A record. Dynamically updates DNS A and PTR records only if requested by the DHCP clients -- is checked Dicard A and PTR records when lease is delete --- is checked. If you were primary/secondary then zone transfers would come into play.
So if i will revert the changes back to the one which you mention so again the previous issue will come into the picture.
pls help Let me explain more on my issue :-Have two DC's server A and Server B , on both the server DHCP and DNS is configured below Server AScope - 192.168.2.0Address pool- 192.168.2.50 - 10.5.2.150Scope - 192.168.4.0Address Pool - 192.168.4.50 - 192.168.4.150Server BScope - 192.168.2.0Address Pool- 192.168.2.151 - 192.168.2.250Scope - 192.168.4.0Address Pool - 192.168.4.151 - 192.168.4.250So can say i distributed the load.And on both the places scope options are configured with the below settings :-Dynamically update DNS A and PTR record only if requested by the DHCP client is CHECKEDDiscard A and PTR record when lease is deleted.But even then this level of security is usually done when doing cross platform zone transfers. Good thing to know so I can add it to my DNS troubleshooting mental database.It is assumed DNS/DHCP are using standard system accounts.Greetings wanderer, i can go with the option which you told me to do that but before that i would like to inform you that earlier i was having the issue that "XP sp 2 machines unable to register their A record in DNS " So i worked with MS support and they did the trouble shooting and informed me to change the settings to the "Dynamically updates DNS A and PTR records only if requested by the DHCP clients -- is checked".After making the settings things worked, but at that time i havenot check the PTR records.
