How do I Share an entire Hard Drive with Everyone on Windows 7?

Are all the computers in the same workgroup? IE: MSHOME, WORKGROUP, ETC....

Are firewalls configured to allow access from/to the network?

What OS is on the computers?

Is every computer equipped with Windows 7? If so is, there's a way to configure a shared map available for every computer connected to the network to access. If the entire drive is to be accessible, this is problably not the solution you are looking for.

Would you rather set up a network with a mainsystem used for storage the other computers are constantly connected to?

This answer isn't really what you are looking for, I'm just trying to help the professionals with supplying eventual info about your requirements they need to help you out  

how are you trying to access the share from the other computers?
Can your share anything on that computer, or is nothing working?

Go to Network and Sharing Center, on your computer you want to share stuff. Make sure your network your connected to has been classified as a Home or work network NOT public (this will disable everything with file sharing). If that is all good, go to "Change advanced sharing settings" on the left side of the screen. Expand Home or Work, make sure
Network discovery is ON
File and Printer sharing is ON
Not sure but you might want to turn Password Protected sharing off, that might be for media sharing and doesn't apply to file sharing, I am not sure.

I had to change the security settings for each user as well and this worked. Thanks everyone.
