...on a load balance web farm.

Is there an easy way of doing this under Windows 2003 Web Edition?
Currently the only thing I've come accross is to use task scheduler to kick off an app every so often that would do the a file check, but that sound clunky. But they seem to expect a source and destination, I don't know on whcih server the files maybe updated.

Doesn't Microsoft's Distributed File System (DFS) do something like this?

Built in? Nothing real easy that I can think of. I do however have personal experience with HP Openview Storage Mirroring that works really well, and is very low bandwidth using. What it does is it sits at the kernel level and watches the filesystem traffic. Any activity to filesystems it is monitoring gets thrown into a queue to be distributed to the mirror. This can be done instantly, or at scheduled times.

The other issue I see with any software though is if it will install on Web Edition. I know the list is pretty short of software Microsoft allows to be installed, for licensing reasons. The above linked software will run on Web Edition, but make sure to check that on any other solutions you might look into.

Thanks Tom. I had a good think about this last night (ah the wonders of beer!) and could not come up with a good reason as to why developers sould be changing files on more then one server. ie change the files on a master server and leave the other(s) alone. In which case it is just a simple robocopy command.

Don't know if I'd be allowed to use that HP software but I might be able to get a copy of LEGATO RepliStor though I do think that it would be over kill for the job.

unison ?
