The DNS lookup test for an on-premises vCenter Server, Platform Services Controller, Site Recovery Manager, or vSphere Replication fails.


One or more DNS lookup tests fails. The Resolved Address text box in the test results shows no result.


If the DNS lookup for a given FQDN fails, the cause might be one of the following:
  • The on-premises DNS server does not have an entry for the given FQDN.
  • You entered an incorrect FQDN for the test.


  1. Ensure that you entered the correct FQDN.
  2. Check that the on-premises DNS server has an entry for the FQDN.
