The situation I have is setting up a small network. The network is for a town. It will only have four computers and a laptop. All will need access to the internet. Two computers are running XP Pro, two XP Home and the laptop is XP Pro. The internet access is through a telecable modem. I have setup a Netgear Prosafe VPN Firewall (FVS318 V3) to act as a router and firewall.
As the police department computers (Desk and laptop) has to be super secure, I don't want them to be able to be seen on the network, but I want them to be able to sync files between themselves. The same goes for the standalone desktop in the Mayor's office. If possible these three need to be able to share printers also.
As these three need to be able to send information to each other, how can I do this without opening them up to the other computers on the network and be secure from outside intrusion?
The other office (water company) has access to the same network (2 desktops - XP Home). They need to be able to see each other, use a shared printer and not be able to see the police department or the mayors, but also be secure from outside intrusion.
As these two do not need any access to the super secure side, how can I block them?
There is no server involved to provide password security. I know this would be better, but I am under a very tight budget restraint. This needs to be done immediately.
Thanks for your help!

2. I thought Windows XP home did not support networking...
I'm not great at networking in XP as I've had very little experience in doing so; so that's all I can really help you with i'm afraid. If it was vista or 7 I'd be able to assist you more

Wireless can be hidden, as in not broadcasting the SSID, and given a WPA2 encryption, that would be a pretty secure wireless network.
I guess also you could set everything on a uncommon static IP range, meaning anyone who does try to hack in would also need to be on that range.

1. start > run > net config server /hidden:yes
or via the registry
Either add a DWORD Hidden or modify it and set value to '1'
To Share files, it sounds like you could setup a NAS.
Most NAS's will allow you to set file permissions, users, user groups, and file shares. Once you've setup your shares, you can map the shares to each computer, or you could do what I did was add another layer of protection by writing an HTA Application (http://thehotfix.net...lp-with-script/) PM me if you need the completed script.
I also made sure that I made the shares hidden, by appending a $ sign after the share name. This makes your share hidden from the My Network Places browser list.
You might want to consider getting a Network Printer. This way you don't have to use simple file sharing, and network administration can be done over the web, like you would find with many HP printers.
As far as security is concerned, wifi is the worst.
- As you mentioned you could disable SSID broadcasting
- Setup Mac Address Filtering
- Setup a IP range for the exact number of computers and networking devices on the network
- Use WPA 2

I am going to have to research the server/hidden item. I think I understand wht it does. Just want to make sure.
There is no budget for a network printer. It would also cause a security problem as it would have to be localized and the different offices are locked for most of the time. A very small town with a parttime mayor and town recorder(secretary).
Hydra, send me the script to look over if you don't mind. I want to get this network up and running secure before Saturday.
