How will windows handle dual networks? (100+1000mb)

[StraightPipe]

I'm adding a gigabit connection between my 2 main rigs in order to get faster file transfers. I already have a 100mb LAN set up and use it to share my internet conection (DSL) between 5 boxes.

I'm wondering if windows will recognize that the 1000mb NIC-to-NIC connection is the quicker of the 2 and use it when i move files from PC to PC.

anybody know?

I believe it depends what you have set as your gateway. If the IP of the router is in there by default, it will got through the router. I've never come across that. So, just giving it my best shot without actually being there to test the speed.

Well, you could just buy a gigabit switch and fast cards for the high traffic paths, then there's be no configuration issues.

well i alreadh have a router on my modem, and a switch into that (for extra ports, all 10/100) both PC's are on the router.
i wanna connect the 2 PC's with the NIC-to-NIC connection so i dont have to buy a $100 gigaswitch.

I'm assuming the router is set to gateway since they are currently connected to it (i'm setting up the giga network next week when i get the parts.)

I'm still stumped, anybody know?

it all goes back to your host routing table.

for example
one nic has 192.168.1.0/255.255.255.0 and a default gateway
the other has 192.168.50.0/255.255.255.0 and no default gateway

anything that communicates on the 192.168.50.0 network goes out that network card
anything that communicates on the 192.168.1.0 network goes out that network card
anything no on those networks is sent to your default gateway

Nothing too it. No magic.

DOH! check your other thread...its explained there.

I've re-read the other thread. I'm still a little confused. also a friend of mine has been helping me, and he insists that it will got through the router as a default.

am I going to have problems with this? or should it work once it's set up? will i have to do something special to force the gigabit transfers?

Follow our instructions on addressing the network cards, masks and gateways.

I can assure you it will most definately not use the router for local transfers. The router or default gateway is for non-connected networks.

If your router is using DHCP it is even easier.

10/100 nic - gets all IP information from the router
1000 nic - manually set IP to an address like 192.168.50.5 with a mask of 255.255.255.0. the other computer is 192.168.50.6 255.255.255.0

When accessing another computer via the gigabit link simply use the 192.168.50.x address. You're all set!

thanks, i'll probly be posting again once i get the hardware setup

So, when I open up Network Neighborhood and select the other machine with the gigabit card, I type the IP address in where? I believe you can do this with the routing table, but I don't see how this works.

You don't have to do anything with the routing table. All of the Microsoft machines will be broadcasting browsing info.
If the interface is "local" (i.e., no "hops") that is the preferred route.

If you want to browse by name, and you don't have a WINS server, then edit your "hosts" file following the example entries.
in NT/2K hosts is found in C:\WINNT\SYSTEM32\DRIVERS\ETC, IN WIN9X it's in C:\WINDOWS\SYSTEM32, in XP it's in C:\WINDOWS\SYSTEM32\DRIVERS\ETC

the original file is "hosts.sam" edit it and save it as "hosts" (".sam" = "Sample").


The default gateway is only for off-LAN addresses where there is no known route in the routing table. The machine first looks at "local" machines (on the same LAN segment /SUBNET/broadcast domain), then any static routes, then any learned routes ... anything left over gets sent to the Default Gateway.

Good Luck

Good point, it's in the routing table, I just don't have to put it there. You're right, I forgot about Microsoft having done something right with their networking.

If I were to just take of file+print sharing on the old PC's 100 line wouldnt that solve my problem instantly?

Is this possible, I've not tried running 2 networks simutaneously. would it work out better if I were running XP on both boxes

 

[spidey07]

follow the directions provided and you'll be fine.

You can try to take microsoft networking off the network cards but in my experience windows doesn't listen and will still use those cards even if you have microsoft networking completely disabled.

Use the IP address of the 1000 Card or place a name in your lmhosts file.
