How to create a wireless intranet w/o internet access?

[ettin]

I'm trying to connect my portables to a central server that has all my music on it, all located in the same area. I've tried ad-hoc but it limits me to using the preset shared folders only, and its frustrating to use as it breaks once a computer leaves the network.

Anyways i just want to create an off-line wireless intranet that will remain persistent even when all computers have left it. This doesnt seem to be possible with built-in windows tools, what program will let me do this?

just use a wireless router and don't connect anything to the WAN/Internet port
