Question

Can't resolve or ping from the server itself for domains setup on the server

Asked by: rot299

Hi

I have a domain (name.com) that it setup on my windows server 2003 server.

I can access (resolve and ping and view in Firefox) this domain name from my computer in my office, however, I can't do any of these when using the actual server itself.

When I do a ping I get:
"Ping request could not find host name.com. Please check the name and try again."

When I try and view in Firefox I get:
"Server not found"

Why is this happening? How can I fix this?
Thanks

from the server itself can you ping the FQDN? ie servername.domainname.com

can you ping its own IP address from itself?

1...  is the server also a primary DNS server?

if so..  any MS Primary DNS Server needs to have as it's primary DNS  ITSELF!!
why on earth microsoft did this I am not sure..
But you must set the primary DNS on the Primary DNS Server to ask itself what it already knows..

2... Name.com ...   is this server hosting the web page???

3... Is your Hosts file modified...
      where is your hosts file???
      C:\WINDOWS\system32\drivers\etc
      how do you know if it is modified??
      there  should be only one line that does not start with #
      127.0.0.1       localhost

Jinx_IT:

I can ping the servers IP, localhost (which returns 127.0.0.1) and also the "computer name". Strangely pinging the "computer name" returns an internal IP address ie. 192.168.0.4

Please note: the "computer name" in the Control Panel - System, is not set as a FQDN like a domain. It is just a name - should it be a FQDN?

toniur:

My office computer uses my ISPs DNS server.

I am not sure what DNS server my server uses. Checking the network card settings, it is set to use itself as the DNS server (it's own IP address).



cdbeste:

1) Yes - the server is also the primary DNS server, in the network settings it is set this way. However, I don't think it should be because I don't run DNS on this server. The DNS is run on other servers.

2) Yes, the server is hosting this domain name. The domain name isn't "name.com" - this is just an example.

3) the hosts file has not been modified.

so the "full name" under the "computer name" tab in System properties just displays the servers name?

ie, just "server" instead of "server.domain.com"

is the server joined to the domain? or in a WORKGROUP?

you say "Strangely pinging the "computer name" returns an internal IP address ie. 192.168.0.4", WHY, what IP address is it suppose to have? not 192.168.0.4?

 

by: rot299Posted on 2008-08-01 at 00:10:10ID: 22136081

cdbeste:

1) No, the server is not a ns1.domain

Jinx_IT:

"so the "full name" under the "computer name" tab in System properties just displays the servers name?"
- yes

The server is part of a workgroup and not a domain.

"you say "Strangely pinging the "computer name" returns an internal IP address ie. 192.168.0.4", WHY, what IP address is it suppose to have? not 192.168.0.4?"
- I thought it would reply a internet accessable IP address and not an internal IP address.

You should configure your server to to use ISP DNS. If you want to use this server as DNS server for others you should configure forwader in DNS console and configure network card to use 127.0.0.1 as preferred DNS.

If you don't want to use DNS service, just configure network card with ISP's DNS as preferred DNS server.

Run "ipconfig /flushdns" in command prompt after each change.

Jinx_IT:

"what is the exact function of this server you are referring too? is it a webserver publish sites to the internet? "
- yes, this is a web server. Shared IP addresses for multiple domains using IIS as the webserver. The domains are all working.

Thanks everyone for all your help - much appreciated!!

Should a web server be part of a domain or workgroup? Or does it not matter?

I changed this to use my ISPs DNS server, and now I can ping the name.com. However, I still can't load the actual name.com in Firefox or www.name.com domain which points back the server itself.

Not on the same topic (I can post as another question if you like):

 in Control Panel / System / Computer Name tab / Change... / More...

Does anyone know what "Primary DNS suffix of this computer:" means/does?

 

by: toniurPosted on 2008-08-01 at 05:30:50ID: 22137575

Primary DNS suffix of this computer, this setting specifies the DNS suffix to be appended to the name of this computer when completing its fully qualified domain name.

Computer can have multiple DNS suffixes, for example:

server.domain1.com
server.domain2.com
server.domain1.local

I found this thread after suffering the same problem.
I solved the problem by deleting the forward lookup zone for my domain.

So if my domain were domain.com and my server name was server.domain.com, I deleted domain.com from the forward lookup zone completely.  I can now resolve my own domain from the server.  The reason I noticed the problem was that I could not ping the domain name from any computer on the network that was using server.domain.com as the DNS server.

Just trying to add information onto the Internet where it might belong.
Regards.
