Can't set a Static IP address for Windows server

Question

_{Monday, October 18, 2010 9:27 PM}

To day I installed an  entrprise version of the Windows server 2008. When I try to configure the server to use a static IP v4 address then I loose internet. If I turn back the configuration to dynamic IP then the internet turns back.

Remarque: I disabled the security enhamcement of the IExplorer from the beginning

The strenge think that I remarqued is that (I have skype installed) it remains connection in both cases and even the network icon remains indication that the connection is established which is wierd. I try to browse I recieve Internet explorer couln't display the page.

I tried with Mozilla same result. So what to do in this case?

You really shouldnt try to troubleshoot this issue at the "Application Layer" of the OSI model.  What I would suggest is for you to write down the DHCP settings, open a command prompt and type IPCONFIG /all).  Take note of your DHCP IP, subnet mask, default gateway, DNS client settings, and WINS settings, if applicable.

Then simply apply the static IP address, using the Network Properties GUI (or netsh if you prefer command line).  You will apply a static IP address from the same network range.  Your subnet mask, default gateway, and DNS and/or WINS settings will be the same so make sure you configure those as well.

If you need further help, feel free to post the results of IPCONFIG /all for both as a DHCP client and static IP client if needed.

Hello,

Do an IP config /all when the system is working and take note of the IP address as well as the DNS IP addresses. When you set the NIC for static, make sure that the IP address is the same (or within the subnet range) as it was in the IP config. Also make sure you have at least one DNS server set up.

Note: Do you have DNS configured? If so, the server NIC DNS IP should point to itself and the DNS should have forwarders set to your ISP's DNS (or a public DNS like Open DNS 208.67.222.222)

Also, please be more specific. Post an IP config as JM asked. Do you have DNS service configured? When you say the Internet does not work do you mean that you are browsing from the server or from a workstation?

What is the result if you:

Ping www.opendns.com

ping 208.67.220.220

ping 127.0.0.1

Hi

I fixed the problem, by setting the static IP adresses

Remarque: The server as Domain controller should refer it self in the DNS IP input

An then I installed the DNS via the server manager as I prompts me requiring static IP adresses and once the DNS is configured then the Internet connection is back again

Thank you
