How Do I make visible on a windows network a test web server for CentOS and WordPress?

I am setting up a test server with CentOS 6 and WordPress. It is almost done. But one problem is seeing the server on the internal network. I can ping the machine and view the site on the box but not on other boxes on the network. The network is a windows based. I can not ping the host name. What do I do next to make it visible on by other boxes. Thanks.
