vSphere Installation and Setup
If the system that you use for your vCenter Server installation belongs to a workgroup rather than a
n
domain, not all functionality is available to vCenter Server. If assigned to a workgroup, the vCenter
Server system is not able to discover all domains and systems available on the network when using
some features. Your machine must be connected to a domain if you want to add Active Directory
identity sources after the installation. To determine whether the system belongs to a workgroup or a
domain, right-click My Computer. Click Properties and click the Computer Name tab. The Computer
Name tab displays either a Workgroup label or a Domain label.
Verify that the NETWORK SERVICE account has read permission on the folder in which vCenter
n
Server is installed and on the HKLM registry.
During the installation, verify that the connection between the machine and the domain controller is
n
working.
Before the vCenter Server installation, in the Administrative Tools control panel of the vCenter Single
n
Sign-On instance that you will register vCenter Server to, verify that the following services are started:
VMware Certificate Service, VMware Directory service , VMware Identity Manager Service, VMware
KDC service, and tcruntime-C-ProgramData-VMware-cis-runtime-VMwareSTSService.
You must log in as a member of the Administrators group on the host machine, with a user name that
n
does not contain any non-ASCII characters.
Network Prerequisites
Verify that the fully qualified domain name (FQDN) of the system where you will install vCenter
n
Server is resolvable. To check that the FQDN is resolvable, type
a command line prompt. If the FQDN is resolvable, the
the domain controller machine.
Verify that DNS reverse lookup returns a fully qualified domain name when queried with the IP
n
address of the vCenter Server. When you install vCenter Server, the installation of the web server
component that supports the vSphere Web 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.
Verify that no Network Address Translation (NAT) exists between the vCenter Server system and the
n
hosts it will manage.
Install vCenter Server, like any other network server, on a machine with a fixed IP address and well
n
known DNS name, so that clients can reliably access the service. Assign a static IP address and host
name to the Windows server that will host the vCenter Server system. This IP address must have a
valid (internal) domain name system (DNS) registration. Ensure that the ESXi host management
interface has a valid DNS resolution from the vCenter Server and all vSphere Web Clients. Ensure that
the vCenter Server has a valid DNS resolution from all ESXi hosts and all vSphere Web Clients. If you
use DHCP instead of a static IP address for vCenter Server, make sure that the vCenter Server computer
name is updated in the domain name service (DNS). Ping the computer name to test this connection.
For example, if the computer name is
command prompt:
ping host-1.company.com
If you can ping the computer name, the name is updated in DNS.
If you will use Active Directory as an identity source, verify that it is set up correctly. The DNS of the
n
vCenter Single Sign-On Server host machine must contain both lookup and reverse lookup entries for
the domain controller of the Active Directory. For example, pinging mycompany.com should return the
domain controller IP address for mycompany. Similarly, the
should return the domain controller hostname. Avoid trying to correct name resolution issues by
editing the hosts file. Instead, make sure that the DNS server is correctly set up. For more information
about configuring Active Directory, see the Microsoft Web site.

nslookup

host-1.company.com
ping -a
nslookup your_vCenter_Server_fqdn
command returns the IP and name of
