I have a simple HTML page on my personal web server at home that contains an HREF tag to allow people to click a word to download a file. Most people don't have any problem downloading the file. However, some do. If I try it from my office network, it does not work.

I know it is not a security issue on my office network because I can download files from other places.

The same thing happens when I try an FTP download. Most people can download. But when I try from my office network, I cannot.

Any ideas?
