80 TCP vCenter Server requires port 80 for direct
HTTP connections. Port 80 redirects
requests to HTTPS port 443. This
redirection is useful if you accidentally
use http://server instead of https://server.
WS-Management (also requires port 443
to be open).
If you use a Microsoft SQL database that
is stored on the same virtual machine or
physical server as the vCenter Server,
port 80 is used by the SQL Reporting
Service. When you install or upgrade
vCenter Server, the installer prompts you
to change the HTTP port for
vCenter Server. Change the
vCenter Server HTTP port to a custom
value to ensure a successful installation
or upgrade.
Important You can change this port
number during the vCenter Server and
Platform Services Controller installations
on Windows.

open for host to join Active Directory. If
you use native Active Directory, the port
must be open on both vCenter Server
and Platform Services Controller.

389 TCP/UDP This port must be open on the local and
all remote instances of vCenter Server.
This is the LDAP port number for the
Directory Services for the vCenter Server
group. If another service is running on
this port, it might be preferable to remove
it or change its port to a different port.
You can run the LDAP service on any
port from 1025 through 65535.
If this instance is serving as the Microsoft
Windows Active Directory, change the
port number from 389 to an available port
from 1025 through 65535.
