If you join a standalone vCenter Server system to a Linked Mode group, the domain name of the system must match the machine name. If you change either name to make them match, you must configure the vCenter Server URLs to make them compatible with the new domain name and machine name.

If you do not update the URLs, remote instances of vCenter Server cannot reach the vCenter Server system, because the default vCenter Server URL entries are no longer accurate.

The vCenter Server installer configures default URL entries as follows:

For the VirtualCenter.VimApiUrl key, the default value is http(s)://FQDN of VC machine/sdk.

For the Virtualcenter.VimWebServicesUrl key, the default value is https://FQDN of VC machine:installed-webservices-port/vws.


From the vSphere Client, connect directly to the vCenter Server instance on which you have changed the domain or host name.


Select Administration > vCenter Server Settings.


Click Advanced Settings.


For the VirtualCenter.VimApiUrl key, change the value to point to the location where the vSphere Client and SDK clients can access the vCenter Server system.

For example: http(s)://machine-name/ip:vc-port/sdk.


For the VirtualCenter.VimWebServicesUrl key, change the value to point to the location where vCenter Server Webservices is installed.

For example: https://machine-name/ip:webservices-port/vws.


For the VirtualCenter.Instancename key, change the value so that the modified name appears in the vCenter Server inventory view.
