Pointer (PTR) records in reverse lookup zone are the ones which allow other computers to locate any computer on the basis of its IP address. Unlike forward lookup zone where IP addresses are resolved on the basis of computer names after proper configuration of reverse lookup zones computer names can be resolved by IP addresses. Pointer (PTR) records can be created at the time of creation of Host (A) records in forward lookup zones and this practice saves a few mouse clicks by the administrators. However if Pointer (PTR) records are not created at the time of Host (A) records creation administrators can create them manually by following the steps given below:
1. Make sure that you are logon to Windows server 2008 computer with the account that has administrative privileges.
2. Go to Administrative Tools by clicking on Start button and from the submenu click on the list.
3. On DNS Manager expand Reverse Lookup Zone tree and right click on the reverse lookup zone that you have created.
4. From the appeared menu click on New Pointer (PTR) and on New Resource Record box click on Browse button under Host name field.
5. On the opened box locate for Host (A) record for which you want to create Pointer (PTR) record and click on Ok button.
6. Back on New Resource Record box click on Ok button to create Pointer (PTR) record for the selected Host (A) record.
