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 220.127.116.11
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
deault gateway:192.168.1.254 --->router
pref dns:18.104.22.168---->main server (jobs)
alter dns server192.168.1.254 ----->router
in advanced i have two ip (192.168.1.6 and 22.214.171.124)
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
