Hi..everyone..
Excuce..My english..isn't very good-lookin' lol..
so I have 3 routers connected directly to a switch and 3 host they're in the same network...

Router 1 ip adress int fast 0/0 192.168.1.1
Router 2 ip address int fast 0/0 192.168.1.2
Router 3 ip address int fast 0/0 192.168.1.3
host 1 ip address 192.168.0.4 DG 1.1
192.168.0.5 DG 1.2
192.168.0.6 DG 1.3
broadcast address for this network is 192.168.1.255
so I want to send a net send to all the host in the network..
example.. net send 192.168.1.255 "Hello people" i can't do it..please..can anybody help me..? thank's
 
Usually you use the command like this:

net send * Hello people



The * means to send to all hosts.

Yup, use the *.

Beware, if you are using that command on Windows XP with serivce pack 2 installed, the Messenger service (which is what the net send command uses) is disabled by default, so your broadcasts will not be recieved by users.
 
The broadcast address is not for humans to use, only for TCP/IP to use. You can on some Cisco router IOS sets ping the broadcast address from the CLI prompt and you will get a response from every host that wants to answer on that subnet.

my question for you, why do you have three different routers all on the same subnet ? why not just one router with four interfaces?

What is the Subnet Masks?
It looks like your Host are on network 192.168.0.0and your routers are on 192.168.1.0. I can asume your mask is 16bit if your hosts true DG are 1.1, 1.2 and 1.3. If that is the case your true broad cast is 192.168.255.255 and not 192.168.1.255.
