If your database is on the same machine on which vCenter Server is to be installed, and you changed the machine name, verify the configuration. Make sure that the vCenter Server DSN is configured to communicate with the new name of the machine.

Changing the vCenter Server computer name impacts database communication if the database server is on the same computer with vCenter Server. If you changed the machine name, you can verify that communication remains intact.

If your database is remote, you can skip this procedure. The name change has no effect on communication with remote databases.

After you rename the server, verify with your database administrator or the database vendor that all components of the database are working.


  • Make sure that the database server is running.
  • Make sure that the vCenter Server computer name is updated in the domain name service (DNS).


  1. Update the data source information, as needed.
  2. To test this condition, ping the computer name.
    For example, if the computer name is host-1.company.com, run the following command at the Windows command prompt:
    ping host-1.company.com
    If you can ping the computer name, the name is updated in DNS.


vCenter Server communication is confirmed. You can continue to prepare other components of your environment.
