Well, like I said, I think a FileSystemWatcher doesn't make sense in a Web application but is more suitable in desktop or Service applications.

What do you expect to happen? Some file changes and then what? The server tries to send a new ASP file to the browser? No way, it's not going to happen.
The Web is stateless by design. What this means is that there is no continuous connection between a browser and the server. The browser requests a page, at the server that page is loaded / constructed and then sent to the client. This loading will only take a second, or maybe even less. When the page has been sent to the client, the server forgets about the client and will see the same client as an entirely new client when the next page is requested.

So in your scenario, as soon as you hit the button, the FileSystemWatcher will be created (I think; I am not even sure it's possible), the page finishes loading, goes out of scope and all objects created during the page's events will be destroyed.

A Web app is just not the right tool for what you're trying to accomplish. You're trying to saw down a tree with a screw driver ;)

Everyone is unique, except for me.

Great analogy! Thanks for your input. Actually, my final result *was* going to be something that could look at a log file, determine that a change event has occurred, and append the changes that occurred to the file to my output display (basically, the UNIX tail command). Looks like I'll have to bark up another tree with a BIGGER saw...
Thanks again.

There seems to be huge inconsistency when I run a FSW on Windows 2003 Server box, as opposed to a Windows XP box, both of which are monitoring a network share directory. Windows XP box seems to pick up 1000 file change events, whereas, Windows 2003 box seems to pick up only 250 events.

Does anybody know of any network file event conditions on Windows 2003, that could be causing this?

Is it generally a bad idea to watch for file change events over the network?

Any ideas or suggestions will help.
