How do I build a simple network?

[ksnyder]

I use my Dell PC as my server. All computers in my office are tied to a
router for internet and printing, but only one of them currently can access
the database on my computer. I want to be able to share information between
my laptop and my PC. How do I establish that link??

Depends on the application.
Does it allow multiple users?.
