Why won't my 735 connect to my work's wifi network?

My 735 won't connect to my work's Wifi network

I have never had a problemwith this before, when I select my work's Wifi network, a message comes up - 'No internet connection. Your phone won't be able to connect to the internet from this network'. It connects nicely to my home Wifi network. Any ideas?

Thanks - Mark
