asp.net error

Hi, I keep getting the following error when trying to load a .aspx page. Has anyone seen an error like this and solved the problem. I am running windows 2003 server that is sitting behind a firewall (which I think might be the cause of the problem but cannot see what I am missing) The page is trying to call a phpbb forum
