Hi
at mid day today 29 /01 all the computers cannot connect to the server..
the server i checked is fine no hardware failure...after a try and try with the connections i found that my modem router dsl was down...i tried i got it up then the connection to server comes back..
i have two dell servers..
one for the main jobs second for the internet and email server..
the main server is 194.125.10.1
second pc is 192.168.1.4
the dsl is 192.168.1.254 (to connect to the router for the )internet

each pc i create an ip as follows
ip:192.168.1.6
deault gateway:192.168.1.254 --->router
pref dns:194.125.10.1---->main server (jobs)
alter dns server192.168.1.254 ----->router
in advanced i have two ip (192.168.1.6 and 194.125.10.7)
when the dsl was down everythings is down
how i can setup this in the future that when i lost dsl i will still have connection to my main server

Is the main server in a different location?  If it is not then...

I would put ALL the machines on the same subnet, for example:

each pc i create an ip as follows

ip:192.168.1.x
deault gateway:192.168.1.254 --->router
pref dns:192.168.1.1---->main server (jobs)
alter dns server192.168.1.254 ----->router

Reassign your servers to be on the same subnet
Main server: 192.168.1.1
Secondary server: 192.168.1.2


Now even if your internet goes down everything inside the lan can still communicate.

remember to take out any statically assigned IPs from your DHCP pool


If your man server is at a different location your will not be able to connect to it if your internet is down.  Sorry, the only option would be to get a back up cable/dsl connection.

Good luck!

Hi
means my job server with ip 194.125.10.1 will be 192.18.1.2..
and each pc i create one ip
like :
192.168.1.x
default gateway:192.168.1.254
pref:192.168.1.1
alter:192.18.1.254
and i will have connection to my jobs and to the internet..

Yes, all your PC's should be on the same subnet (for the simple and effective setup)
