File and Print Sharing ports and firewall restrictions and DFS?

victor2008 used Ask the Experts™

Therefore, I would need to allow all subnets (within the company) access to the 20 file servers File and Print Sharing ports, correct? That is, for each file server, I should add a custom list of subnets to the File and Print Sharing firewall rule that includes all the company subnets?
