not real clear on what you are trying to accomplish here. you cannot chmod any files on windows vista or any other windows environment. are you trying to run a server on your local machine? i suggest you get an application such as wmserver tools and setup the webserver. if you are trying to use IIS, then i cant help you out on that. but there are tons of applications on the net that are open source. wamp, xamp, wmserver-tools and many more.
you can also setup an ftp server so you can login via local host and that would allow you to chmod those files, but i dont think you are going to have any luck changing the file attributes in windows vista the way you are going about it.
