Gigabit Network

Just wanting to know if I am doing this correctly

I have 3 computers, 1 has a 10/100 lan and 10/100/1000 lan card installed,
the other 2 systems has 10/100/1000 lan cards, I also have a 4 port 10/100
adsl all in one modem/router and a 5 port 10/100/1000 switch.

So what I want to do is have the computer with the additional 10/100/1000
nic card install able to transfer files from one of the other 2 computers at
1GB, I have bridged the system that has the 2 nic cards installed, do I plug
the computers nic running 10/100/1000 to the gigabit switch and the 10/100
nic into the all in one router?

Why? Are you using ICS or some other proxy software? What does each connect
to?

I'm presuming your modem/router has a firewall and does NAT and DHCP.... ?
If not, get a small firewall/gateway appliance that does, and stick it
between your modem & your LAN.

Pretending you don't have two NICs in that PC, you'd plug
everything, including the DSL modem or router, into your 10/100/1000
Ethernet switch.

If you're using ICS/etc, connect the 10/100 NIC to your DSL modem, connect
the 10/100/1000 NIC to the Ethernet switch, and connect all the other
computers to the same switch.

Hi
All of the Giga Computers/Cards have to plugged into the Giga Switch
configured as a second Network (I.e. not the same subnet as the Router and
the 100Mb/sec NIC) and the tow Networks should Not be connected with any
cable between them.
One computer with two Cards has to run WinXP Pro and has to be configured as
a Bridge.
Since you have a Router do not use ICS, use straight Bridging.

The computer with 2 nic in connects to the 10/100 4port 3COM adsl router and
the 10/100/1000 nic connects to the 1GB switch then I bridge both
connections in Network connections, I'm not using ICS, is this the wrong way
to do it
the other 2 computers with GB nic is connected to the 1GB switch

OK - but why?

Does the 3COM do NAT and DHCP? If so, get rid of the bridge, disable your
10/100 NIC and connect the 3Com directly to the switch, and connect your GB
card to the switch.

Maybe; I suspect so. What do you hope to accomplish with the bridge?

I think I'm getting a bit excited here Lanwench.
The 3COM is a
http://www.3com.com/products/en_US/detail.jsp?tab=features&pathtype=purchase&sku=3CRWDR101A-75

It is set to DHCP not sure about NAT, but it's listed in the router and is
not checked where it says diasble NAT.

I thought I would benifit somewhat from a bridge but guess I'm looking at it
in a totally different light.

I've disabled the 10/100 card on the desktop and now using the GB nic, all
computers with 1GB LAN is plugged into the Gigabit switch, now while
transferring a 2GB file over the network it's only transferring at 35 mB/sec
what's going wrong here? I've put in CAT6 cables for extra performance

If you connect a single computer to the Ethernet switch on the 3com, you'll
get a private/non-routable IP, right? If so, there you go.
Disable bridging, disable the 10/100 card, and see what happens.

Yep.

Try locking down the NIC settings at 1000/full, and see whether you can get
it to connect.

I've changed the settings to 1000/full on both computers and still getting
around 20 mB/sec transfer rate, what should it be over a 1GB LAN?
