Difference between cross-over cable and straight-through cable

I tried to connect two computers by UTP cable, it worked on both straight-through and cross-over. Why?

The answer is when your computer have built-in auto-crossover (a.k.a. auto-switching or auto-MDI/MDIX) port that lets a computer connect directly to another computer using a straight-through cable. A crossover cable is also used to connect two hubs (or switches) if both hubs (or switches) don't have uplink ports.

Straight-through cable is used to connect a computer to a hub or a switch. It can also be used to connect two hubs (or switches) if each hub (or switch) has an uplink (i.e. built-in crossover) port.

HP LaserJets - Cold Reset Instructions

Cold resetting a printer resets the printer to factory defaults.Please note: Any settings you make at the printers control panel will be reset to factory defaults, including the IP address if you have a JetDirect card installed. Remove the JetDirect card while you cold reset the printer if you don't want to erase the JetDirect card's settings. You can also reset the NVRAM. Resetting the NVRAM will clear the page count and reset the service mode settings to factory defaults. On printers with a display panel you need to enter service mode to manually change the information stored in NVRAM. On printers that don't have a display panel, such as a 5P, 6P, 2100, 2200 there is a different procedure outlined below.

"Older" printers with a display panel. (e.g. 4000, 4100, 5si, 8000, etc.) Cold resetting the printer is simply a matter of turning the power off, holding down the GO or Online button while turning the printer on. Resetting NVRAM settings must be done manually through service mode. See entering service mode. "Newer" printers with a display panel. (e.g. 2300, 2400, 4200, 4250/4350, 4300, etc.) Turn the printer off and then on. When the printer begins its memory count, press and hold down the Checkmark button until all the main LED signal lights illuminate and stay illuminated. Then release the Checkmark button, and use the Up/Down arrow keys to find the Cold Reset option, then press the Checkmark button again to choose that option. Printers with no display panel. HP 1100, 1200 - While the printer is on, press and hold the Go button for 5 seconds. This will reset the printer. To reset the NVRAM. Turn the printer off. Press and hold the Go button for 20 seconds while powering on the printer. HP 2100 - To perform a cold reset, turn the printer power off, then press and hold the JOB CANCEL button. Turn the printer power back on and after all the LEDs come on release the JOB CANCEL button. A cold reset changes most system parameters in NVRAM to the factory defaults. The JOB CANCEL button must be released within 20 seconds after all of the LEDs come on; otherwise, an NVRAM initialization is performed instead of a cold reset. HP 2200 - Cold reset: 1. Turn the printer power off. 2. Press and hold GO. 3. Turn the printer power back on and continue to hold GO until the Attention light turns on. 4. Release GO. 5. The device lights will begin cycling from front to rear. The cold-reset process will run until completion and the device will go to the ready state. NVRAM Reset: 1. Turn the printer power off. 2. Press and hold GO. 3. Turn the printer power back on and continue to hold GO until the Attention, Ready, and Go lights turn on. 4. Release GO. 5. The device lights will begin cycling from font to rear. The NVRAM initialization will run until completion and the device will go to the ready state. HP 5P & 6P Cold reset: Turn the power off and hold the reset button (button closest to the back of the printer) for LESS than 20 seconds while turning the printer on. Reset the NVRAM: Turn the power off and hold the reset button for MORE than 20 seconds while turning the printer on..

Solution:
Steps to clean Virus Definitions folders and republish Live Update Product Inventory on Symantec Endpoint Protection Manager:

1. Delete the content of folder "c:\documents and settings\All users\Application Data\Symantec\LiveUpdate\Downloads\"
   Note: Application Data is a hidden folder. Delete the content of the Downloads folder, but not the folder itself.
2. Update the LiveUpdate catalog by opening the following link in Internet Explorer:
   http://localhost:9090/servlet/ConsoleServlet?ActionType=ConfigServer&action=PublishLuInventory
   After few seconds you will get a confirmation message "Responsecode="0".
3. Stop the services "Symantec Endpoint Protection Manager" and "Symantec Endpoint Protection"
   To stop the services:
   1. Go to Start > Run.
   2. Type the following: Services.msc
   3. Select and stop the above mentioned services.
4. Delete the numbered or TMP folders inside the paths:
   • %programfiles%\symantec\symantec endpoint protection manager\inetpub\content\{1CD85...
   • %programfiles%\symantec\symantec endpoint protection manager\inetpub\content\{C60DC...
   • %programfiles%\common files\Symantec Shared\SymcData\sesmvirdef32
   • %programfiles%\common files\Symantec Shared\SymcData\sesmvirdef64
   • %programfiles%\common files\Symantec Shared\VirusDefs
5. Launch the process LUALL.EXE from %programfiles%\Symantec\LiveUpdate (May be requested to click on "START")
   (LiveUpdate should run for some minutes (5-10 min), if some error messages are displayed, exit and launch again LUALL.exe)
6. Restart both Symantec Endpoint Protection services when LiveUpdate is complete.
7. Verify the numbered folders of virus definitions are created in the following paths:
   (There might be just 2-3 folders in the beginning, but the default number is 10 folders)
   • %programfiles%\symantec\symantec endpoint protection manager\inetpub\content\{1CD85...
   • %programfiles%\symantec\symantec endpoint protection manager\inetpub\content\{C60DC...
     
8. Log on to Symantec Endpoint Protection Manager Console and launch a LiveUpdate from Admin > Server > Local Site > Download LiveUpdate content.

Verify the correct download/usage of new virus definitions from "Admin > Server > Local Site >Show LiveUpdate Downloads".

Note: In Server 2008, the Downloads folder in step 1 is located at C:\Program Data\Symantec\LIveUpdate\Downloads

How to share one Internet connection with another computer using Vista?

If you have two computers at home, one is connected to the Internet. The computer A with Internet must have two network cards. It can be wireless and LAN card or two LAN cards.

The computer A (with Internet), 1 LAN card is connected to the other computer (Computer B).

First let me explain how to connect two computers in LAN.

Step 1: In Vista, before doing this you should enable Sharing and Discovery. You can do that by going to Control Panel -> Network and Sharing Center. Under the section ‘Sharing and Discovery, enable Network discovery, File Sharing, Public folder sharing and others if you want to. (See picture below)

Here, first network represents connection to internet and second one the local connection with another computer.

Step 2: If your LAN card that is connecting to another computer is installed, it will be shown under Control Panel -> Network Connections.

Step 3: Right click that local area connection and click properties.

Step 4: Under the tab ‘Networking’, click the properties Internet Protocol Version 4 (TCP/IPv4).

Step 5: Click the radio button to ‘Use the following IP’ and give an IP address (For example, IP address: 192.168.0.1 and Subnet Mask: 255.255.255.0)

Step 6: Don’t give any other information, Click Ok and close everything.

Step 7: In computer B, make sure you enable the LAN card which is used to connect to computer ‘A’. Here you need not give any IP information as Computer ‘A’ will assign an IP address dynamically. If it’s not working make sure there are no IP assigned and change the properties to ‘Obtain an IP address automatically’.

Step 8: Test the connection by pinging. (You can do this by typing ping 192.168.0.1 or whichever is Compter ‘A’s IP in the comand prompt)

Sharing the Internet connection of computer ‘A’ with computer ‘B’:

Right click LAN card which is connected to Internet under Control Panel -> Network Connections and click ‘Sharing’ tab and enable both the options to share Internet. (Note: Unless there is another enabled LAN setting you will not be able to see the shared tab under properties)

Click Ok and close. This option is given by the Windows OS known as ICS (Internet Connection Sharing).

Now you can use Internet from both Computer A and Computer B from a single connection.
