KB937056: Static IP addresses in Windows do not save¶

In some versions of Microsoft Windows, you may manually configure the TCP/IP properties dialog to add a static IP address. After closing and re-opening the dialog, 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.

Symptoms¶

In Windows, the Internet Protocol (TCP/IP) Properties dialog box displays the default IP address settings after you manually configure a static IP address creating the impression that static IP addresses information was not saved or remembered by Windows.

Cause¶

Microsoft has confirmed that this is a problem in some versions of Microsoft Windows. See KB937056

Resolution¶

Follow the remediation steps described in KB937056 to remove the HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Network registry key.

For reference, on Page 575 of "Windows 2000 Server 24seven" by Matthew Strebe (ISBN 978-0782126693) the author describes the registry object ...\Control\Network\* and its subkeys as a store which "contains keys that create the bindings between network adapters, clients, services and transport protocols".

Notes¶

This is not a problem caused by Enclave, but a bug in Microsoft Windows. Some customers may encounter this bug during routine use of the product, which may also interfere an administrators ability to use Enclave effectively.
