Two PC's behind router cannot see each other. WinXP Pro, Simple File Sharing enabled

Using WinXP Pro:

Simple File Sharing is enabled, and both PC's are behind a router with DHCP-assigned IP addresses. Why can't they see each other? This particular desktop can't even see itself on the network.

Are both computers on the same workgroup?

Yeah. It turns out that I had to enable both Client for Microsoft Networks and File and Printer Sharing. I don't know why they were disabled.
