I have a LinkSys wireless router. There are four machines that are hard wired to the router, and they see each other and are able to share files, etc. I have two laptops that are on the router wirelessly. They can't see the other machines, and the other machines can't see them. The laptops can see the internet but can't see the local workgroup computers.

At one time, they worked. I've tried disabling Kaspersky Internet Security firewall, but it doesn't seem to matter.

Both laptops are on XP Home Edition SP3. All the wired machines are XP Pro SP3.

Thanks for any helpful comments!
