SUS Server Problem - W2003

I have two problems with SUS server on our W2003 Server.
>
>1. Syncronizing server works fine and a get a bunch of
>new updates but the approve update page is blank.
>Logging on susadmin locally on the susserver with the
>administrator account.
>Have solved it temporarly with a script that
>automatically approves all new updates, but why is the
>page blank?
>
>2. Have configed the OU with group policys that are
>correctly installed on the client.
>Looked in their registry and the setting seems ok. They
are
>configured to automatically install updates at 12 every
day.
>But the clients doesn't even try to contact the
susserver. Nothing at all shows
>in the windows update.log
