SYMPTOMS
You run the following command to disable the TCP/IP Version 4 (TCP/IPv4) protocol on all network connections on a Windows Vista-based computer:

netsh interface IPV4 uninstall

You restart the computer, and then you view the properties of a network connection in Control Panel.

However, the Internet Protocol Version 4 (TCP/IPv4) check box is still selected. Therefore, the properties of the network connection incorrectly show that the TCP/IPv4 protocol is enabled. This behavior occurs even though you disabled the protocol from all network connections on the computer.



CAUSE
This problem occurs because the properties of a network connection are not updated correctly in Control Panel after you run the netsh interface IPV4 uninstall command to disable TCP/IPv4.



WORKAROUND
To work around this problem, use either the Ipconfig.exe command-line tool or the Netsh.exe command-line tool to verify or modify the TCP/IPv4 settings.



STATUS
Microsoft has confirmed that this is a problem in the Microsoft products that are listed in the &quot;Applies to&quot; section.



MORE INFORMATION
When you experience this problem, you cannot re-enable TCP/IPv4 on a network connection if click to select the Internet Protocol Version 4 (TCP/IPv4) check box. After you disable TCP/IPv4 by running the netsh interface IPV4 uninstall command, you must run the netsh interface IPV4 install command to re-enable TCP/IPv4 on a network connection.

For more information about the Ipconfig.exe command-line tool and the Netsh.exe command-line tool, see Windows Vista Help and Support.
