How to register a vCenter in vSphere 5 Web Client from command line

If you don't want to install Adobe Flash player in your server running vSphere 5 Web Client, then you can do that from a command line:

• cd \Program Files\VMware\Infrastructure\vSphere Web Client\scripts

• admin-cmd register https://vsclient.mydomain.local:9443/vsphere-client vcenter.mydomain.local <username> <password>

where vcenter.mydomain.local is the vCenter address, vsclient.mydomain.local is the vSphere Web Client address (it may be the same server where vCenter is installed), <username> is an Administrator account in vCenter and <password> is his password.
Open this link from a browser to check the web client: https://vsclient.mydomain.local:9443/vsphere-client/
