The connector software will require the Administrator password of your home server anyway and usually can be installed directly from the WHS.
Which version of Windows Home Server do you use? For WHS 2011 the link would be
https://servername/connect
For resetting the admin password you would need either to reinstall the server or use a more tricky way (if your WHS has a interface to connect a screen).
