Can flash player have access to my local network

I’ve got a flash site that is hosted as usual on a webserver.
I need to allow the end user to watch an FLV which is located on the local network, not on the webserver where the site is.
Is it possible to get the flash player on the end users pc to be able to access the local network?

the contentPath is something like:
video.contentPath = “”\server1\folder1\vid.flv";

Any help would be great, I can’t get this to work at all
