Just upgraded (reluctantly) from IE 7 to IE 8, and now I can't open a Microsoft Access database that I was able to get to before (on IE 7). This datasbase is located on another PC on our interoffice (peer-to-peer) network. The message is "Microsoft Access cannot open this file. The file is located outside your intranet or on an untrusted site. Microsoft Access will not open the file due to potential security problems. To open the file, copy it to your machine or an accessible network location." I ran into this same problem when I upgrade from IE 6 to IE7 but I can't remember how I fixed it.
