How to reset Internet Protocol (TCP/IP)

Use a manual method to reset TCP/IP:

The reset command is available in the IP context of the NetShell utility. Follow these steps to use the reset command to reset TCP/IP manually:

  1. To open a command prompt, click Start and then click Run. Copy and paste (or type) the following command in the Open box and then press ENTER:
    cmd
  2. At the command prompt, copy and paste (or type) the following command and then press ENTER:
    netsh int ip reset c:\resetlog.txt
    Note If you do not want to specify a directory path for the log file, use the following command:
    netsh int ip reset resetlog.txt
  3. Reboot the computer.
When you run the reset command, it rewrites two registry keys that are used by TCP/IP. This has the same result as removing and reinstalling the protocol. The reset command rewrites the following two registry keys:
SYSTEM\CurrentControlSet\Services\Tcpip\Parameters\
SYSTEM\CurrentControlSet\Services\DHCP\Parameters\

To run the manual command successfully, you must specify a file name for the log, in which the actions that netsh takes will be recorded. When you run the manual command, TCP/IP is reset and the actions that were taken are recorded in the log file, known as resetlog.txt in this article.

The first example, c:\resetlog.txt, creates a path where the log will reside. The second example, resetlog.txt, creates the log file in the current directory. In either case, if the specified log file already exists, the new log will be appended to the end of the existing file.

Java Control Panel Icon "Application Not Found"

Howto: Fix the "Application not found" error in the Java Control Panel icon. These same steps may be useful for other malfunctioning Windows Control Panel icons. In Windows 7, the Java Control Panel icon may be damaged / corrupted. Attempting to launch the icon results in "Explorer.exe : Application not found". Note the generic icon: When working properly, the circled icon should look like this: This problem appears to be an artifact from previous JRE installations and Sun's installation routines were flawed. Re-installing JRE (the Java Runtime Environment) does not resolve the problem. Immediate workaround: If needed, the Java Control Panel can be manually launched using this location: C:\Program Files (x86)\Java\JRE6\bin\Javacpl.exe As a side note, when launching, other-mouse-click the .exe and choose "Run as Administrator".  Running as Administrator resolves a bug where changes in the Control Panel (especially Auto-update changes) do not stic
