It doesn't work that way, that you ask - "my network doesn't work, help me" and somebody miraculously has a solution (well, it may happen, but not often).
Usually, nobody can really help you without detailed info, so publish details, do troubleshooting tests, publish results -- this is how it works.
Such questions are the first coming up:
What system do you use - based on ZD, vSZ or Unleashed?
Are these shared folders on the server which is on the same subnet and VLAN as WiFi clients or on a different subnet?
What authentication mode you have on WiFi is it using Radius authentication?
Can you ping file-server from WiFi client?
Do you have WINS server on your network?
What happens if you try to map shared folder as networking drive manually, printing a path, using server IP, not a name?
