Can't ping DNS

[Guest john]

I have a network of 3 machines running 2k3. The server can get on the

internet, but the workstations can't get on it. Also the workstations

can't ping DNS with name or address. They also can't ping the gateway

on the WAN side.

Would appreciate any help.

RE: Can't ping DNS

 

What is your setup; you have any routers or anything?

You should be able to ping the server and the gateway, can you be more

specfic?

The server is multi-homed. One is connected to the internet and the

other connected to the LAN. The public one is the only one connected

to the router and the private one and the other two machines are

connected to a hub.I checked and there was no firewalls on the

machines. Are there any ports besides 53 I need to open?

Ok..

 

So you have a server with 2 nics; one cable is going to the internal LAN,

the other cable is going straight into the router. The clients G/W should be

the server or it could be the adsl router; and their dns servers should be

the servers.

 

If you can't ping by IP then DNS isn't your only issue; you shouldn' thave

to really open any ports on the hub; is the hub working? can the 2

workstations on the hub ping each other? You have everything in the right

subnet and ip scope?

Yes all computers can ping each other, up to the server's LAN side.

They cannot ping the gateway on the WAN side and so they can't get on

the internet. They also can't ping the DNS.

Re: Can't ping DNS

 

Ok, let's work on the DNS issue first.

 

If all the machines can ping each other on the LAN via IP address and not

via DNS you have a DNS issue.

 

Are the workstations using the server's IP address as their primary dns? I

assume DNS is installed and functioning correctly on the server.

 

Do you have any firewalls in place?

 

With regards to the Internet; have you configured routing and remote access

in Windows 2003 server? Why don't you just use a router that interfaces

directly with ethernet and have that as your gateway and point the

workstations to that IP address.

 

What kind of switches do you have in place?
