Hi, I am trying to restart the vCenter Web Client service and noticed that the options are grayed out. vCenter6.5 is installed on Windows 2012R2.
Please refer the attachment.
I think this is not supported, instead use "service-control" utility to re-start the web-client.
check other service may be we can not anything inside web-client for web-client service , check in services.msc
I will check in my lab ... shortly confirm to you
See this link Restarting vCenter web services options are greyed out for Administrator@vSphere.local
Also check what permissions you have if your not using firstname.lastname@example.org, you may need more to be able to restart those from the webclient.
