NexusE. Thanks for dropping by. You are correct. iDisk is available on Windows. I forgot about that; which is odd since I wrote an article on how to do it. LOL.

MobileMe and iDisk however do not work at all behind a corporate firewall with proxy servers. This is what Apple has to say:

Check for proxy servers

If you use a proxy server to connect to the Internet, you may need to talk with your network administrator or Internet service provider (ISP) to find out if the proxy server supports WebDAV connections. WebDAV is the protocol used to allow your computer to interact with the iDisk. Sometimes a proxy server may be running outdated software that does not allow WebDAV connections. If your proxy does not support WebDAV connections, the network administrator or ISP may be able to give you information to enter in your network preferences that would enable you to bypass the proxy server when connecting to the Me.com domain.

The whole point of web proxy servers is to allow the company to control how it's network resources are being used and to mitigate legal liability (from porn etc). So why would the network security admin tell a user how to bypass the proxy?

I am the web gateway (proxy) security policy manger for my employer and I know that our (brand new) appliances support WebDAV. The problem is that MobileMe is coded to use port 80 instead of whatever the Internet Explorer settings are.
