This issue may occur if you have name resolution problem on your physical server.

To resolve this issue, ensure your DNS settings are configured properly on your physical server:
  1. Verify that your DNS server is running and not malfunctioning and you are able to resolve DNS from the source to vCenter Server and the ESX host. In a Microsoft Active Directory environment, this is generally your Domain Controller.
  2. Attempt to ping your Domain Controller by hostname. If the ping fails, attempt to ping the machine by IP address. For more information, see Testing network connectivity with the ping command (1003486).
  3. If you can ping your Domain Controller but DNS queries are failing, check to see that your guest machine is set to use the Domain Controller as its preferred DNS servers.

    1. Click on Start > Run and type control netconnections.
    2. Right click on the active network adapter for physical server and click Properties.
    3. Select the item in the list for Internet Protocol (TCP/IP), and click Properties.
    4. Select the radio button for Use the following DNS server addresses.
    5. Check to see if the IP addresses match those for your Domain Controller/Active Directory Integrated DNS server, and if not, add the IP addresses of your Active Directory servers.

  4. Ensure that the hosts file entries do not conflict with DNS. If a hosts file is configured locally, any host name-to-address mappings are loaded from that file when the DNS client starts and may cause issues with resolution locally.

    To verify this behavior:
    1. Click Start > Run, type %systemroot%/system32/drivers/etc/, and click OK.
    2. Open the hosts file using a text editor.
    3. Look for lines similar to:

      <ip address associated with hostname> <hostname in your environment>

      For example: localhost

    4. If information here conflicts with information that should be in DNS, remove it and allow your DNS server to be authoritative for name-to-address mappings.
