Problem when select "software update"

Hi guys,
I upgraded my Tiger Server to Leopard Server last 2 weeks, but there is a problem that everytime when i select 'Software Update' in apple then it tells me this:
"software update can't connect to the update server. Make sure you're connected to the internet, then try again.
Software update can't check for the updates because of a network problem"
My Leopard server connect to internet just fine. But I don't know why it keeps saying that message every time. any idea ? Thanks

sign in and out of app store
shut down iphone
reset iphone
reset network setting
