Cisco Catalyst Password Reset

October 23, 2014 Leave a comment

In the event that you forgot any remote login password, there is no way to recover the password but there is away to change the password and retail all the configuration.

1) Put the switch in ROMmon state.
2) Initialize the switch with command flash_init
3) Rename the flash:config.text file to flash:config.text.renamed
4) Boot the switch.
5) After rebooting, the switch is back to factory setting, copy the renamed config file to the running config.
6) Amend the remote password, save and reload.

Reset Internet Protocol (TCP/IP)

July 26, 2010 Leave a comment

One of the components of the Internet connection on your computer is a built-in set of instructions called TCP/IP. TCP/IP can sometimes become damaged or corrupted. If you cannot connect to the Internet and you have tried all other methods to resolve the problem, TCP/IP might be causing it.

Because TCP/IP is a core component of Windows, you cannot remove it. However, you can reset TCP/IP to its original state by using the NetShell utility (netsh).

Follow these steps to use the reset command to reset TCP/IP manually:

  1. Open a command prompt, click Start then click Run. Type cmd into the box and press ENTER.
  2. At the command prompt, type the following command and press ENTER:
    netsh int ip reset reset.log
  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 registry key:
