To run PowerCLI cmdlets on vSphere and perform administration or monitoring tasks, you must establish a connection to an ESXi host or a vCenter Server system.

You can have more than one connection to the same server. For more information, see Managing Default Server Connections.

If your login credentials contain non-alphanumeric characters, you might need to escape them. For more information, see Providing Login Credentials.

If you use a proxy server for the connection, verify that it is configured properly, so that the connection is kept alive long enough for tasks to finish.


If you do not want to use a proxy server for the connection, run Set-PowerCLIConfiguration -ProxyPolicy NoProxy.

Run Connect-VIServer with the server name and valid credentials.

Connect-VIServer -Server -Protocol http -User 'MyAdministratorUser' -Password 'MyPassword'
