Recently I have made some major changes to my PC which make me think that I need to review my file sharing policy.
I have moved from dial-up internet to broadband and installed a 3Com router firewall.
The home network has 3 PCs which have file sharing enabled on all drives The Share Permissions tab allows 'Network' change/read permissions. The 'Security' tab allows 'Everyone' full control. (MS Office gives problems if I don't allow full access). This sounds a bit risky but as I understand it 'everyone' means anyone who logs on with the correct username and password. However, I must admit to being confused between the W2k 'Shares' properties 'Share Permissions' and 'Security'.
Since the NAT on the router makes the PCs invisible to the outside world and the file shares are protected by password access then it seems safe.
My installation is: W2000 Office 2000 Outpost PFW The PCs are not logged on with admin privileges except when doing Windows updates. The router provides IP addresses to the PCs
