256986 Description of the Microsoft Windows registry
In Windows Server, you manually configure the TCP/IP properties to add a static IP address. After you do this, the Internet Protocol (TCP/IP) Properties dialog box still displays the default settings. Additionally, the Obtain IP address automatically option is selected.
However, when you type
ipconfig /all at a command prompt, the static IP address information that you entered manually is displayed.
Serious problems might occur if you modify the registry incorrectly by using Registry Editor or by using another method. These problems might require that you reinstall the operating system. Microsoft cannot guarantee that these problems can be solved. Modify the registry at your own risk.
To resolve this problem, follow these steps:

If your server is a domain controller, go to step 5. (This includes servers that are running Windows Small Business Server 2003.) If your server is not a domain controller, delete the following registry subkeys:
Click Start, click Run, type
sysdm.cpl, and then click OK.
In the Systems Properties dialog box, click the Hardware tab, and then click Device Manager.
In Device Manager, expand Network adapters, right-click the network adapter that you want, and then click Uninstall.
Restart the computer.
After the computer restarts, the operating system automatically detects the network adapter. If the network adapter isn't detected, you may have to manually reinstall the network adapter drivers.
