how to remove DNS zone Delegation

Hey,

Each of those entries can be deleted if we're only dealing with DNS.

I guess you're not manually creating those? Does the zone accept Dynamic Updates? What else is the zone used for (Active Directory?)?

Chris

hi,

yes it is integreted with AD, i am not creating this entries manually , it creates automatically next days, when i see ,

i have made some changes like delegation dns zone, but now it creates automatically host record for that record which i delegate.

now i want to remove delegation.

If the zone holding those records is for AD then it isn't suprising. Those records are added because AD needs them to function properly. It allows you to lookup the domain name and get the IP addresses for every Domain Controller in reply.

What did you delegate?

Chris

I delegate the DNS Zone like,

In my domain webbased application is running , for company requirement that which webpage  opened externally from outside out network (internet) same we can open it in internal,

so i did the one  host entry in dns  like www, for that we can open www.hostname of server and webbased application will be opened,

but when another website is host on same webserver , then company wants that same website will open same way,

so I delegate the WWW host record to another wesite .

like first it is www. test.co.in   (like test is my server hostname)
second it is www.home.com

now the problem is that when the application team type in address bar  http://test  then website is open but another home.com,
because of DNS host entry in dns
it creates
172.16.25.10      test   ( this is the right)
172.16.25.10      home (this entry i have to delete manually daily)

Hmm kind of getting there.

You're using the wrong terminology. Delegation is a very specific operation in DNS, but it isn't what you're doing here. It's been confusing me :)

Is "home.com" the AD Domain Name? If it is, you will not be able to do "http://home.com" without compromising Active Directory.

Chris

No,

My domain name is test.co.in and  my website is running with same domain name like
www.test.co.in
we have created one more website like home.com

problem is that all are working www.test.co.in site is opening, www.home.com is opening from external.

but in internal network, when my application team in the morning time type http://test the website is open home.com not the test.co.in

because of host entry, which i have earlier mentioned.

Any chance you can show me a screen shot of this?

I need to know exactly what's been created and what you're expecting to happen.

Is this one a Host (A) record?

172.16.25.10      test   ( this is the right)

Do both sites run on the same web server? If so, are you using Host Headers to separate the sites?

Have you created a new DNS Zone for "test.co.in"? Or are you adding records under "home.com"?

Chris

yes, I will show you the screen shot tommorrow once it will create new entry.

Hi ,please find the attached screenshot yesterday and Today.

now you will see that ,

yesterday i take a screen shot, and today, webserver entry
created automatically,

Cool, thanks for that :)

Is "webserver" the actual server name? Does that zone have dynamic updates enabled?

Chris

Yes ,

webserver is my server hostname.and my DNS has Dynamics Update are enabled.

but letsstayhealthy is not a domain name i have created only for website to be open in my internal network in DNS. and this is not a server.

LetsStayHealthy points to the same IP address in both screenshots though, so that's not a problem is it?

So where is the name for webserver being used in such a way that this is a problem?

Chris

hi ,

letsstayhealthy is rights but my concern is ,why the webbserver entry is creates automatically,

I don't want the double entry with same host name but ip address is diffrenet.

i wants only one entry of webserver with 172.16.25.68 host entry, not webserver 172.16.25.76 host entry.

Is the second IP Address (the one that appears automatically) assigned to the host?

Deleting the record and recreating it doesn't remove it's rights to update. You could select Security, then look for an entry in the list for WebServer, removing that will prevent i updating the record.

Chris

I have checked on security tab, but nothing found.

Is the second IP Address (the one that appears automatically) assigned to the host?

I'm curious why you need to change the address here.

Chris

no 172.16.25.76 is the ip address that is i have given to the webserver second NIC card ,

on my weserver there is two NIC Card , one is 172.16.25.68,and second is 172.16.25.76,

i think i got the cause why its creating automatically,

but can it be possible that 172.16.25.76 ip address could not create host entry in dns ,

becuse the problem is that on 172.16.25.68 (webserver) some other site is open,and on 172.16.25.76 ip address some other site is hosted,

due to the dynamics update in dns , it creates the host entry
webserver=172.16.25.76

and when user type the url http://webserver main site is not opened second site is opened,

or IS it possible that when user type http://webserver , it will not points to another site it will point its original site,
any settings in IIS ?
