XP network and file security tips tips

Is your computer shared with people? If so, you will be concerned about the security of your personal files. If you are using the Windows XP operating system, then you can use Windows XP to provide some simple and efficient settings to maintain your file security.

1. How to make XP automatically connect to the Internet

IE—— Tools——internet option——Connect, check "Dial when the network does not exist" Pull IE to "Start" After each boot, you are already online! There is another way: enter the connection content, cancel the checkmark of the prompt name, password, credentials, etc., and then put The connection is pulled to “start”.

2, quickly browse the local area network sharing

Normally, Windows XP will check all the scheduled tasks on the other machine when connecting to other computers. This check will let you wait. 30 seconds or more. The method of removing is found in the registry "HKEY_LOCAL_MACHINESoftwareMicrosoftWindowsCurrent VersionExplorerRemoteComputerNameSpace".

Under this key, there will be a {D6277990-4C6A-11CF-8D87-00AA0060F5BF} button, delete it, restart the computer, Windows XP will not check the scheduled task, the speed will be Significantly improved.

3. Encrypting files and folders

Encrypting files and folders makes it impossible for unauthorized users to read them. To encrypt a file or folder in Windows: Open “Windows Explorer'; right-click on the file or folder you want to encrypt, select the <;Properties" option, and click the “General” In the card, click the “Advanced” button and select the “Encrypt content to protect data” check box (this operation is only available for NTFS file system).

When encrypting a folder, the system will ask if you want to encrypt all the files and subfolders in the folder at the same time. If you choose to do so, then all the files or subfiles in the folder that are currently and will be added in the future. Folders will be encrypted; if you choose to encrypt only folders, the files and subfolders currently in the folder will not be encrypted, but any files and subfolders added to the folder will be encrypted when they are added. When encrypting a single file, the system will also ask if you want to encrypt the folder containing it at the same time. If you choose to do this, all subsequent files and subfolders added to the folder will be automatically encrypted.

4, improve the 10/100M network card transmission rate

Select “ start → connect to → display all connections & rdquo;, double-click the connection used by the network card, click & ldquo; attributes & rdquo; Button, open the “Properties” dialog box and select the “Advanced” tab. In the "Properties" column, select “Link Speed/Duplex Mode", and then in the "Settings" column, change "Auto Mode" to “10 Half Mode”.

In this way, the 10/100M adaptive NIC's attributes are manually forced to 10M half-duplex mode, so that auto-negotiation is not performed between NICs, so that the NICs always transmit at 10 Mbps. Greatly improve the transmission efficiency between networks. This setting is only valid for some NICs.

5, shared drive or folder settings

Windows XP can be used to easily set the drive or folder to "share" &, if you do not want these shared drives Or if the folder is seen by a remote computer user, simply add a "$” after the shared name of the shared drive or folder, such as “C$”. However, when the remote computer user knows the computer name of the machine and the user name and password of the administrator and server operator, then any remote computer user can access the computer through the local area network or the Internet. Undoubtedly, this also enables the shared drive. There is a security risk in the computer of the folder or folder. To secure the shared drive or folder, we should disable the server service. When the server service is disabled, all remote computers will not be able to connect to any drive or folder on that computer, but the administrator of this machine will still be able to access shared folders on other computers. To disable the server service, go to “Control Panel>——“Performance and Maintenance ——“Administrative Tools", double-click “service”icon, at "service In the window, double-click the “Server” option to see the dialog box shown in Figure 1. In the “Startup Type” list, select “Disabled” or “Manual”

6, solve the problem of WinXP execution pause

Start & mdash; — network connection & mdash; & mdash; local connection, right click, select properties, select “ Internet Protocol (TCP /IP) & rdquo;, click on the property, use the following IP address: 192.168.0.1, subnet mask: 255.255.255.0, this is fine, and will not stop after booting.

7. Set the folder as a dedicated folder

By default, all folders in Windows XP are open, that is, all users on the machine can use them. This undoubtedly poses a serious threat to the important personal data of some users. To this end, Windows XP has added a feature called "folder-specific", which refers to a folder in the NTFS file system that is set to "private folder" by the user. It can only be used by this user, and other users can't use it after logging in to Windows XP, which is convenient for protecting important personal information. To make a folder dedicated, simply move the folder to the folder "x:\\Documents and Settings\\username\\” (where x is the partition where the Windows XP installation files are located), then right click on the folder Folder, select the "Properties" option, check the "Share" tab in the "Share” tab to make this folder personal, so that only I can access the ” checkbox. In this way, when other users want to enter this folder after logging in to Windows XP, they will be prompted to "deny access".

8, Accelerated Sharing

This is a great optimization. Before I found this optimization, I often waited for the window to display the shared directory on other machines to break the scalp. .

Normally, when Windows XP is connected to another computer, it will check all the scheduled tasks on the other machine —— this is superfluous, and it will let you wait for 30 seconds, it is too bad It is.

Fortunately, it is easy to ban this process. First, find HKEY_LOCAL_MACHINE\\Software\\Microsoft\\Windows/Current Version\\Explorer\\RemoteComputer\\NameSpace in the registry. In it, there should be a {D6277990-4C6A-11CF-87-00AA0060F5BF} button. Just delete it, restart the computer, Windows will not check the scheduled tasks, the speed is significantly improved!
