can not ping hostnames of other subnet

[Hasan Numanoglu]

Hi,

I have set up a routing and remote access server, and connected two subnets
(192.168.1.1 / 24 - 172.16.0.0 /16) They re perfectly pinging their ip
addresses but can not ping hostnames of other subnet. Then i tried to ping
with ping -a
command this time, it pinged the ip arddress and find the hostname of the
machine on the other subnet. What can be the problem ???


Thanks

Anytime you are trying to ping by hostname, the name needs to be resolved to
an IP. You need to verify this name resolution is working ( DNS, WINS ) If
this is a simple environment, and you want to just prove concept, you can
edit the %Windir%\System32\Drivers\etc\hosts file and add the machines'
names and IP addresses to the file ( Note you need to only do this on the
machines that you want to resolve the names on ). Otherwise, verify your
DNS \WINS settings. Can you reach the DNS \ WINS server? Are you getting
answers back from the DNS \ WINS server with the appropriate information?

Thanks i can ping when i write hostnames but still i can not add member
server from the second subnet there is no incoming outgoing filter on the
router, i can ping dns server with ip and hostname( with writing host file)

It can not find the domain name from other subnet so i can not add member
server??? What can be the problem? Thanks for help

USE NSLookup to perform a DNS query against your DNS server. If your query
times out, try using a network analyzer ( NetMon.exe i.e. ) to see where
your packets are going etc.
