Example: The operating system is XP, win2000, the recent fast start bar is not, even if it is checked, the system will prompt "Can't create the toolbar"? Solve: First, confirm that the quick start-up directory exists. For XP or 2K, the directory is in C: / Documents and settings / [username] / Application Data / Microsoft / Internet Explorer / Quick Launch. If this directory does not exist, create it with IE4uinit.exe under the System32 directory. If the above is executed, there will be an error, then perform the following statement regr32 / i shell32.dllregsvr32 / i braowseui.dll in "Run", then restart Windows. It should be possible now.
Restore the "Show Desktop" button in Quick Start
Just use a text editing software, enter the following: [shell] command = 2Infile = Explorer.exe, 3 [taskbar] command = Toggledesktop then saves the file named "Show Desktop .scf", then drag and drop this file directly "Quick Start" in the lower left corner taskbar.

Easy to detect if the IP address in the network is occupied
Here I gave you a script, through this script we can automatically detect the computer in the network to see which IP addresses online. For example, we have to see 192.168.1. * What addresses have been online in this network, follow these steps.
Step 1: Right click on the desktop to create a new text file.
Step 2: Copy the following code to the text file. FOR / L %% I in (0, 1,255) do ping 192.168.1. %% i -n 1 arp -a -> ip.txt
Step 3: Save the text file after modifying the text file after being exit. Bat. This generates a batch file.
Step 4: Double-click this batch file to automatically search 192.168.1. * All IPs in this network, and save the ARP information to the IP.txt file. (Figure 3)

Step 5: After the scan is completed, we can see the IP.txt file directly and what IP addresses have been used. This file saves information such as all computer IP addresses in the network and corresponding MAC addresses.
hint:
This method is also applicable to the case where the firewall cannot ping. Because the principle is to send an ICMP package to all IP addresses in a certain network segment, perhaps the other computer blocks the ICMP package but not tight, because he will definitely respond to the package of a MAC address to give the source computer, so that locally in ARP -A ARP cache can see his IP address with the MAC address.
In addition, if you want to interrupt, you can use the ctrl c command. Maybe you feel that you want to complete the scan task in the batch file, you want to complete the scan task through the instructions in the command line mode, just need to make the command simply modify I.e. Enter for / l% I in (0, 1, 255) do ping 192.168.1.% I -n 1 to scan, and enter the arp -a -> ip.txt command saves the information. The difference is that it is required to be %% I in the batch file, and the command direct input method only needs% i.
