Connecting diferent networks

Hi,

I have this scenario:

I have one domain with a network with the PCs with fixed IP 193.1.1.1-254.

I created a new domain where we have a DHCP server with the scope
192.168.1.0.

Now I will create accounts for the users in the new domain and i'will change
the Pcs from old domain to the new one.

In the old domain their all work in shares of the server, so between the
time that it will take to change all PCs from one domain to the new one I
need that the guys that are already in the new domain could access the
shares on the server of the old domain to continue to working. How can i do
it if they are in diferent networks?

Thanks in advance.

I presume that the machines are all in the same segment (ie plugged into
the same hub/switch).

They will not be able to see each other without an IP router. If there
is no other connection it is straight forward. You set up a device as the IP
router and make that device the default gateway for both subnets. eg

193.1.1.x dg 193.1.1.254
|
193.1.1.254 dg blank
IP router
192.168.1.254 dg blank
|
192.168.1.x dg 192.168.1.254

If you want either subnet to connect to another network or to the
Internet it gets a bit harder.

Hi Bill again,

Sorry but I don't if I understand correctly.

I have all the computers in two switch. you are saying that I can get an IP
Router, for example
http://www.linksys.com/servlet/Satel...VisitorWrapper
and setup it with one IP address from one of the networks and then connect
the switches to the router and setup the pcs gateways from both networks to
the IP that I had gived to the router.

Is that it?

If they are on different switches, you need a router to connect the two
networks together. The device you use as the router doesn't really matter.
You can even use a Unix or Windows workstation. The important thing is that
the router has an interface in each network and IP routing is enabled.

What happens is this. If the target machine is in the same IP subnet as
the sender, the data is sent directly (sometimes called "on the wire"). The
sender gets the hardware MAC address of the target and sends directly on the
Ethernet link. If the target is not in the same IP subnet, the data is sent
to the default router. The router then delivers it in the other subnet. It
can do this because it has an interface in the target subnet. (The router
receives a packet from one Ethernet segment and delivers it in the other).
