DNS servers lose AD zone data on restart

Good day,

Two DNS servers are serving zone data to my Active Directory domain. The servers are set as Standard Primary and Standard Seconday respectively.

If the DNS service is restarted on either server, it fails to reload the AD zone. No events show up in the DNS log to explain the disappearance. Any ideas?

Thank-you for any help offered.

You have two domain controllers. Right? If yes then why not creating zones to Ad Integrated ?

Advice.

Why you say "AD Zone" here. You are using Primary/Secondary zone because AD Zone are AD Integrated and zone data are kept in Active Directory and for Primary/Secondary zone data are kept in the file in \Winnt\System32\DNS\.

How you reload zone. Do you reload in this way: -

Right click on Zone and then click on "Reload" or you stop and start DNS Server from the console.

Let me know.

Thanks

SystemProg, thanks for the advice but I've just solved the problem.

Under the DNS server's properties, there's an Advanced tab that includes a setting to indicate where to load the zone data from. It says load the zone data from a file or from Active Directory & registry. The setting was to load the data from AD & registry while in fact the zone was stored in a .dns file. On changing the source to "file", the DNS server reloaded the AD zone data properly on restart (which I was doing from the context menu of the DNS server, All Tasks, restart).

Cheers,

Regarding the comment:

>>AD Zone are AD Integrated and zone data are kept in Active Directory and for Primary/Secondary zone data are kept in the file in \Winnt\System32\DNS\.

... you can store the AD zone data in a primary - seconday single-master model but I agree, it's the better practice to integrate this data into the Active Directory. It's just that I've been watching the problem in this thread for some time before migrating the data to AD-integration.

Cheers,

Good: -) Glad you solved it. That's what i was worried about the file. Did you notice my first comment "Primary/Secondary loads zone from file"

SystmProg,

Thanks for your speedy response. I assigned Grade B because I had already come to the solution on my own by the time I read the posts and because the answer, while leading, was not direct.

Thanks again and cheers,
