Problems with the server setup

Hi,

we have a small network,like 10-15 laptops connected between by a router,also do a have a server for the company.

I was trying to install the openfire server on my pc,and then the Spark application on all of the laptops.Unfortunately,only logging in from my computer gives acces to IM.for other pc's gaves that server is unreacheable.

The domain that i used in setting up openfire was my ip adress.

Is somebody that can help me about that?

Thank you!
