Did you publish the site from FrontPage, or by using an alternative FTP method ?
Have you ever copied the site root folder to CD then back again to the hard drive ?
Which version of FrontPage and Windows are you using ?
I'd imagne that was has happened is you have published the web and in the process of publishing, the services.cnf file has been marked read only. It should be read and write to the owner (you) and read only to the rest of the world.
It is possible to get corrupt files in a web, so we can't rule this out, but since the error is telling you what the problem is (read only means it can't be opened or written to) we might be able to do a little bit of tweaking to sort things out.
Get back to me with the above and we'll go on from there.
