You need to go to:
Other Information - Fog Settings, then change the FOG_VIEW_DEFAULT_SCREEN to:
LIST
(the default setting is SEARCH)

Is fog service running on the system? Double check that the fog client is installed and see if that helps you out.

Do do this go to the webpage:

[url]http://<your-fog-server-ip>/fog/client[/url] and download and install the client on the machine. Then try deploying the snap-in.

Got answer to silly qwestion

Tnx. I found answer! Need to edit /opt/fog/service/etc/config.php and /var/www/fog/commons/config.php. Need to edit root pasword to be the same in both files.
