Reverse lookup zone configuration for vCenter

[Ranjna Aggarwal]

Is there who can tell me why reverse lookup zone configuration is required for vCenter because at the time of vCenter installation there is statement reverse lookup zone is not configured some of the services may not start like that statement is pop up. Can anyone give me the example of those services also.

Hey Thanks for moving the conversation to correct group

The vCenter server installer will perform a reverse DNS lookup and confirming if there is an entry for the server.All you need to do is first confirm if infact a reverse lookup zone exists on the DNS server. This most likley will be on an Active Directory Domain Controller and replicated too all other DCs in the domain/forest. So a single point of config can add this for all DNS servers if there are more than one.

Go to your DNS server and add a new reverse lookup zone for the IP range that the server exists in. You will notice your server still does not appear in the reverse lookup zone.

Next we need to request the server to register its adaptors in DNS updating the records already held and not - in this case our reverse lookup zone record.

ipconfig /registerdns

Refreshing the DNS Manager console will now show the pointer record for this server in its reverse lookup zone.

Pressing backing the back button then next again will confirm this issue is now resolved. If the reverse lookup was still not working correctly this test would fail again and the warning dialog would be shown again.

Happily now continue the installation/upgrade....

Hi, Again My question is not that how to configure Reverse Lookup Zone. It is i want to know what are services of vCenter those need REVERSE LOOKUP ZONE Configuration?

The documentation doesn't give the exact technical reason for it, but at least what the reverse lookup zone is needed for.

from DNS Requirements for vSphere

Ensure that DNS reverse lookup returns a fully qualified domain name  when queried with the IP address of the vCenter Server. When you install  vCenter Server, the installation of the web server component that  supports the  vSphere Client fails if the installer cannot look up the  fully qualified domain name of the vCenter Server from its IP address.  Reverse lookup is implemented using PTR records. To create a PTR record,  see the documentation for your vCenter Server host operating system.
