Hello, I installed the VCenterServer 6.5 on a Windows 2016 standard server. It's in a Domain. When i install the vmware Service under the local User it works until I change the User to a Domain administrator. then I get this Message:

503 Service Unavailable (Failed to connect to endpoint: [class Vmacore::Http::LocalServiceSpec:0x000001d47454d440] _serverNamespace = /ui action = Allow _port = 5090)

same when I use the Flash Client (just another Port).

when go back to the Install User, now the website gives me the same Failure.

If I try to stop and restart the vsphere client, I get this message:

Perform start operation. vmon_profile=None, svc_names=['vsphere-client'], include_coreossvcs=False, include_leafossvcs=False

2019-07-25T14:07:54.279Z   Service vsphere-client state STOPPED

Error executing start on service vsphere-client. Details {

    "resolution": null,

    "detail": [

        {

            "args": [

                "vsphere-client"

            ],

            "id": "install.ciscommon.service.failstart",

            "localized": "An error occurred while starting service 'vsphere-client'",

            "translatable": "An error occurred while starting service '%(0)s'"

        }

    ],

    "componentKey": null,

    "problemId": null

}

... and when I try to start all Services new, I got several messages like this:

          ......xxx does not seem to be registered with vmon

just a new Installation works.

Thanks for you help and please excuse my bad english.
