ATM Record

The ATM Address resource record maps domain host name with ATM address. The following shows creating ATM resource record.

1. Assume the dnsserver on which to create ATM Address is "dnsserver", domain zone is "myrootdns.com".

2. Open Dns Manager using the command "dnsmgmt.msc".

3. In the console tree, go to the dns zone "myrootdns.com", right click on zone and select "Other New Records".

4. In Resource Record Type dialog, Select ATM Address list item and click "Create Record"

5. In the New Resource Record Dialog, Enter ATM address and click OK.


6. Click "Done" button in resource record type dialog.
7. In the dns manager, verify the ATM resource record created.

MB Record

The MB(MailBox) record maps a domain mail box to a specified host.

For example, the domain is myrootdns.com, mail box for the domain "myrootdns.com" can be mapped to a machine say "dnsserver.myrootdns.com"

The following illustrates adding mail box record to a domain.

1. Assume the domain is "myrootdns.com", the authorize dns zone for the domain is "myrootdns.com", the server which is going to host mail box is "dnsserver".
2. Open dns manager snapin using the command dnsmgmt.msc.
3.In the console tree, browse to the dns zone "myrootdns.com", right click on the zone, select "Other New Records".

4.in the resource record type, select "mailbox" list item, click create new record.

4. Enter MailBox host name "dnsserver.myrootdns.com"

Delete Dns zone

The following illustrates on how to remove forward lookup dns zone,
1. Assume the dns zone is "mydomainzone.com".
2. Open DNS snap-in manager using the command dnsmgmt.msc.
3. In the dns manager console tree, browse to the zone node "mydomainzone.com" , right click on the zone and click delete.
4. for removing reverse lookup zone(assume reverse lookup zone is 1.168.192.in-addr follow the same procedure

Remove Application Directory Partition using dnscmd

To remove a ApplicationDirectoryPartion say "ExamplePartition.myrootdns.com" using dnscmd.exe command, do the following

1. Verify the directory partion ExamplePartition.myrootdns.com









It can also be verified by running the following command

dnscmd /EnumDirectoryPartitions

2. Now run the following to delete the directory partition

dnscmd /DeleteDirectoryPartition ExamplePartition.myrootdns.com

Create builtin directory partitions

By Default, when the DNS is installed, a application directory partition is automatically created at the forest and domain levels. If these didn't created while installing DNS, the dns manager console can be used to create builtin active directory partitions.
The following illustrates creating builtin directory partitions in dns manager console.

1. Assume the dnsserver name is "dnsserver".
2. Open DnsManager using the command dnsmgmt.msc.
3. In the dns manager console tree, right click on dns server node "dnsserver" and select "CreateDefaultApplicationDirectoryPartitions" option.

Remove CNAME (Alias)

To delete (CNAME) alias from a dns server, do the following.

1. Assuem the dns server name is "dnsserver", dns zone from which alias to be removed is "myrootdns.com" and name of the alias to be deleted is "myalias".
2. Open dns manager snap-in using the command dnsmgmt.msc.
3. In the dns manager console tree, expand "dnsserver" node and browse to the dns zone "myrootdns.com" , In the right panel, right click on the alias "myalias" and select delete..

Create New PTR resource record

This resource record maps a reverse DNS domain name based on the IP address of a host to the forward DNS domain name of that host.

The following show on how to create PTR records in a dns server called "dnsserver".

1. Assume the dns server name is "dnsserver", domain name of the host is "dnsclient", IP address of the host dnsclient is "192.168.1.200"

2. Open dns manager console by using the command dnsmgmt.msc

3. Now in the console tree, browse to reverse lookup zone, right click on reverse lookup zone and select "New Pointer(PTR)".













4. In the New resource record dialog, enter IP address and fully qualified name of the host














5. Thus PTR record has been created in the reverse lookup zone and one can verify it in the dns manager console.

SecureResponses Registry Key

This registry determines whether to cache all or only the Name Sever (NS) records in the same subtree of the domain.

By default, the DNS server saves all the NS records of recursive name queries in the dns memory cache. However, if the reg key value is 1, then DNS server saves only those NS query response records for names that are in the same subtree as the server that provided them.

For example, the DNS server will save all name server (NS) records for subtree.mydns.com from the mydns.com server, but it will not save the Name Sever(NS) record for subtree.notmydns.com the mydns.com server.

The registry key is located at "HKLM\SYSTEM\CurrentControlSet\Services\DNS\Parameters".

Key Name: SecureResponses
Type:     DWORD (Boolean)
Default:  NoKey (No secureresponses)

Value:   0 (The DNS server saves all name query records in its memory cache)
         1 (The DNS server saves only those NS records that are in the same
     subtree of origination dns server)

To set value of this key, then run

reg add HKLM\SYSTEM\CurrentControlSet\Services\DNS\Parameters" /v SecureResponses /t reg_dword /d 1
Note, The changes through regedit.exe are will be effective only after restarting the DNS server.

To change secureresponses with out restarting dns server, do the following

1. Open DNS manager using dnsmgmt.msc command
2. In the dns manager console tree, right click on the dns server node and click properties.
















3. In the dns server properties dialog, go to AdvancedTab and check "Secure cache against pollution" option, click apply and finally click OK button.

set norecursion using dnscmd command

To set norecursion using dnscmd, do the following

dnscmd /config /NoRecursion 1


one can verify norecursion is set by using the following command

dnscmd /info /NoRecursion







Below shows on how to set recursion using dnscmd.exe,

dnscmd /config /NoRecursion 0

DNS Enable Recursion

To enable recursion for performing name resolution for a dns query, do the following.

1. Open dns manager using command dnsmgmt.msc.











2. In the dns manager console tree, right click on dns server (assume server name is dnsserver"), then click properties.
















3. Go to advanced tab, uncheck disable recursion option, press apply and click ok. Thus enabled recusrion on dns server "dnsserver"




















To disable recursion, go the same steps 1 to 3 but just check the "disable recursion" option.

Select DNS Server BootMethod Option in DNS Manager

To select bootmethod for a dnsserver through DNS manager UI, do the following

1. Assume dnsserver name is "dnsserver"

2. Open DNS Manager using command dnsmgmt.msc

3. In the console tree, right click on dns server node, select properties and go to the advance tab,

and select one value for LoadZone data.

Add DNS Manager Snapin to MMC

To add DNS Manager to MMC do the following

1. launch mmc using the command mmc
2. In the console window, open File menu and click Add/Remove Snapin.
3. In the Add/Remove SnapIn dialog, click add button.
3. In the Stand Alone Add/Remove SnapIn dialog select "DNS" and press Add button
Thats it the add-in for DNS Manager SnapIn is added to MMC.

Instead of using mmc snap-in, dnsmgmt.msc command to open dns mananger
