Dividing PC's on Network

I have 5 computers on a network with one DSL router. I would like to setup 2
different network domains on this one connection. For instance, 3 pc's on
MSOFFICE and 2 on GOLDOFFICE using the same router but one domain unable to
access the other. Is this possible with XP.

Not simply, without adding extra hardware.

With one router, ( say on 192.168.0.1 ) all the machines will need to share
the same range of IP addresses ( eg 192.168.0.x ).

With additional hardware, you could subnet up this address space and
hardware firewall between the subnets.

With no additional hardware, the best I can suggest is to:

1) Install XP-SP2;

2) statically assign the machines in one workgroup to one range, say
192.168.0.2 thru 192.168.0.127, and the second workgroup 192.168.0.128 thru
192.168.0.254. All with Subnet Mask 255.255.255.0, and Default Gateway
pointing to the router at 192.168.0.1.

This means they can all access the Internet via the router.

3) Then use the Windows Firewall to specify File and Print Sharing
exception, but adjust the scope to the limited subnet of that workgroup.

Exceptions Tab;
Select F+P sharing;
Edit button;
Change Scope;
Custom List;
Enter a list of IP addresses, eg
On all machines on workgroup 1, enter:
192.168.0.0/255.255.255.128
This means addresses 192.168.0.0 thru 192.168.0.127.
On all machines on workgroup 2, enter:
192.168.0.128/255.255.255.128
This means addresses 192.168.0.128 thru 192.168.0.255.

Now, each wokgroup is firewalled from each other as far as file and print
sharing is concerned.

( I'm writing this from a theoretical standpoint, I've not tested it. )

Jerry, I don't think that those web pages answer the question that
"kycruiser1" asked.

I wrote the one on PracticallyNetworked. It describes the Windows
TCP/IP settings and gives troubleshooting steps for some common
networking problems.

The other one doesn't apply to Windows XP. With a couple of
exceptions, the settings that it describes don't exist in Windows XP.

"Kycruiser1", I don't think that it's possible to do what you want
with your current network setup. Windows XP was designed to allow all
of computers on a network to communicate with each other.

I suggest that you get two more broadband routers, which are commonly
available for $30 or less at computer and office supply stores in the
USA. Connect each group of computers to LAN ports of its own new
router. Connect the WAN (Internet) port of each new router to a LAN
port of the old router. Each new router must use a different subnet
than the old one. For example, if the old router uses 192.168.1.x,
use 192.168.0.x on the new ones.

One way is to add to more routers to your configuration. Another way is to
setup firewall software on each computer to ignore the IPs of the Network
you dont want to have access.

Example:
Network 1 IP Addresses 192.168.0.20, 192.168.0.30 and 192.169.0.40 Subnet
255.255.255.0
Network 2 IP Addresses 192.168.0.100, 192.168.0.110 Subnet 255.255.255.0

You would goto the computers in network 1 and open the windows firewall
(SP2). then click on the exceptions tab. Double click on File and Printer
Sharing. You will have to click on all options in this window one at a time
and select the custom feature and enter all the IPs in Network 1 seperated
by comas and click OK.

Now goto Network 2 and do the same thing, except enter Network 2s IP
addresses.

That should do it.
