Hi folks, I'm still trying to get Mathematica to get through our corporate proxy and firewall. At home everything is fine, even though I run a firewall on my PC and use a NAT router. I've given the network administrator the user-agent string that Mathematica uses when it does its http requests (they are restricting http requests to a fixed list of clients, with the respective user- agent strings used to detect allowable clients). I got that by sniffing my local network. At the office network (which has a http proxy and a firewall running on separate machines) it seems Mathematica doesn't get so far as to make this request. I can see a few packets (3 or 4) exchanged between the proxy and my PC (TCP SYN and ACK) and then everything stops. IE and Firefox don't have a problem getting through. I have traced the update function of Acrobat and can see its user-agent string appear on the network. I tried both the "Use the proxy settings of my system or browser" and explicit proxy settings in the Internet connection tab. I copied the proxy settings straight from Firefox where they do work, so it can't be a typo. I seem to remember that a week ago the connection button responded directly with a fail message. Now, it takes a few minutes, but is still fails. The documentation mentions that this might be the result of using SOCKS where it isn't allowed. I may have tried SOCKS before, but I have removed the setting now, so this shouldn't be an issue. I have emptied the https, ftp and socks boxes, but can't seem to clear the port number boxes (I set them to 0 for now). As far as I can see, this is a problem with SetInternetProxy that can be called with an empty host string, but not without port number. Any clue? Thanks -- Sjoerd
