Modify registry to enhance network functions

We can regard the registry as a huge database, which collects the configuration and status information of all software and hardware of the system and various user-related settings, it plays a vital role in the normal operation of the system. If we are a system maintainer for Internet cafes or public data centers, we should make full use of the unique functions of the Registry in the network to enhance the practicability of the LAN or the efficiency of surfing the Internet. Today, I have collected some operation skills on the Registry's network applications. I hope these skills will be useful to everyone.
1. Hide servers in the LAN
In general, we can use our network neighbors in the LAN to see which computers are currently working, so as to share resources on these computers. However, in practice, we sometimes want to hide the name of the specified server computer in "Network Neighbor" to ensure security, especially the security of servers in the LAN. So how can we hide a server in "network neighbor? In fact, it is very simple. You only need to follow the steps below: First open the editor operation window and click the following branch in the editor dialog box: HKEY_LOCAL _ MACHINE \ SYSTEM \ CurrentControlSet \ Services \ LanmanServer \ Parameters key value. Click the name of the Hidden value under the key value. If this name is not found, add a value whose data type is REG_DWORD. Next, double-click this item, and enter 1 in the pop-up "DWORD Editor" dialog box.
2. Modify the search engine in the browser
In the registry, expand "HKEY_LOCAL_MACHINE \ Software \ Microsoft \ Internet Explorer \ Search ", in the window on the right, change "CustomizeSearch" and "SearchAssistant" to the search engine we have defined. "Target = _ blank> empty.
3. the login network timed out and the connection to the server is automatically disconnected
We often need to log on to the NT server, but it may take a long time to log on to the network due to incorrect login parameters or other reasons, we don't want to see this situation. To solve this problem, we can configure idle timeout disconnection through the Registry, in minutes. The specific steps are as follows: Open the registry editor window and find the following key values: [HKEY_LOCAL_MACHINE \ SYSTEM \ CurrentControlSet \ Services \ LanmanServer \ Parameters]; then select the "AUTODISCONNECT" key value in the list on the right of the editor; finally, double-click the "AUTODISCONNECT" key value, and the editor will pop up a dialog box named "string Editor". In the text bar of this dialog box, enter the value "1 ", 0 indicates that the automatic disconnection function is canceled, and 1 indicates that the automatic disconnection function is used.
4. Change the dynamic effect of the browser window
If you want to change the Registry as follows when you open or close the IE window: Open the Registry Editor operation window, in this window, click the HKEY _ CURRENT_USER/Control Panel/desktop/WindowMetrics key values with the mouse in sequence, create the string values "Minanimat" and "Maxanimat" in the window on the right, and set the value to "0" and "1 ", in this way, the IE window is incrementally changed during the minimal switchover.
5. Improve network access speed
For dial-up users, time is money. How can they save time and money? The answer is to increase the network transmission speed. So how can we improve the network transmission speed? As you know, the network speed is mainly restricted by the network bandwidth. Increasing bandwidth is not what dial-up users can do. The only thing they can do is to increase the transmission speed of the modem. In fact, dial-up users can also start from the computer's own running speed, as far as possible to explore the maximum potential of the computer in network acceleration. Below we will try to speed up network transmission through some settings. The specific settings are as follows: First, expand the following key values in the Registry Editor window: [HKEY_LOCAL_MACHINE \ System \ Current Control Set \ Services \ Class \ NetTrans \ 000n \, where n indicates the number of network connection entries for some numbers, in the list box on the right of the editor, select the "MaxMTU" key value name. If the preceding key value does not exist, you can use the "new" key value command in the "edit" menu to add one, select the Data Type "DWORD" value, select the specified key value, and double-click it. When the "string Editor" dialog box appears, enter "576" in the "string" text box ", 576 indicates the maximum transmission unit value. In the Editor menu bar, select "edit"> "add"> "string value". A new string is displayed in the List window on the right, name it "MaxSSS", double-click the string value and set it to "536", and then expand the following key values in sequence: [HKEY_LOCA Rochelle MACHINE \ System \ Current Control Set \ Services \ VxD \ MSTCP]; follow the same operation method described above, in the list on the right of the editor, add the string values "DefaultRcvWindow" and "DefaultTTL", and set their values to "2144" and "64" respectively ", at last, when you restart the computer to log on to WINNT, the computer will exert its maximum energy in network acceleration.
6. Change the default download directory of the browser.

If you often use IE to download files online, the browser stores the downloaded content in the "C: \ WINDOWS \ Desktop" directory by default, that is, put it on the Windows desktop. After a long time, the desktop will be messy! To keep the desktop clean and tidy, and to effectively manage the downloaded files, some users need to change the default download directory of IE to a special download folder, for example, in the "C: \ download" directory. Therefore, we only need to start the Registry Editor for Windows 98 and expand the HKEY_CURRENT_USER \ Software \ Microsoft \ Internet Explorer key values with the mouse in the editor window, in this case, you can find a string value named "DownLoad Directory" under the Internet Explorer key value. Its default value is "C: \ WINDOWS \ Desktop ". It is used to define the default IE File download path. We only need to modify it as needed, for example, change it to "C: \ download", and then use IE to directly download the file, the system will directly save the file to the "C: \ download" directory.
7. Automatically log on to the server
Generally, you must enter your own user name and password before entering the NT network. However, WINNT also provides the ability to automatically access WINNT with the user name and password of a group at startup, without the need to manually set the parameters to log on to the network. To enable automatic login, you must configure the following: first, in the open registry editor, expand the following key values: [HKEY_LOCAL_MACHINE \ SOFTWARE \ MICROSOFT \ windows nt \ current version \ WINLOGON], and then click "AUTOADMINLOGON" on the right, the editor will pop up a dialog box named "string Editor", enter the value "1" in the text bar of the dialog box, and then select the "DEFAULTDOMAINNAME" key name on the right, enter the name of the DOMAIN name to be logged in or the name of the computer to be accessed in the pop-up text box. For example, enter the name of the "DOMAIN or" COM "computer, click "OK". Follow the same operation method, select the "DEFAULTUSERNAME" key value name on the right, and enter the name of the user logging on to the network in the "string" text box, for example, enter the ADMINISTRATOR name "ADMINISTRATOR" and click "OK ". In the volume table Editor, click the "edit" menu and select the "new key value" command from the drop-down menu. Then, in the list on the right of the Registry, enter the key value "DEFAULTPASSWORD", the key value type is "REG_SZ", and then click "OK". Then, double-click the "DEFAULTPASSWORD" key value, in the displayed dialog box, enter the user password. Here, enter the password of the system administrator as the password for logging on to the network. after entering the password, click OK to complete the setting.
8. Prohibit Access to a floppy disk through the network

To prevent viruses from intruding into the entire network and paralyze the entire network, we must strictly manage computer input devices to cut off the source of the virus. Therefore, we must disable access to the floppy disk through the network. When setting, click Start and select Run Command from the pop-up menu. Then, the program will pop up a run dialog box, in which the regedit command is entered, then, in the open registry editor, open the key value [HKEY_LOCAL_MACHINE \ SOFTWARE \ Microsoft \ Windows NT \ CurrentVersion \ Winlogon]. in the window on the right, check whether the key value AllocateFloppies exists. If no, create a DWORD Value, set the name to AllocateFloppies, and change the value to 0 or 1, 0 indicates that the domain can be accessed by all administrators, and 1 indicates that the domain can only be accessed by local administrators.
9. added the automatic identification function for the website.
If you want to access a website such as www.aaa.com, you only need to enter aaa in the address box, and IE will automatically add it. com suffix for access, saving a lot of trouble. However, if we want to access a website like www.aaa.com.cn, it is not that convenient, because IE does not include the automatic connection function with the. cn suffix. Can we expand the auto-match function of IE to automatically match suffixes such as ". gov", ". net", and ".com.cn? The answer is yes. We only need to start the Registry Editor of Windows 98, and expand the HKEY_LOCAL_MACHINE \ SOFTWARE \ Microsoft \ Internet Explorer \ Main \ UrlTemplate branch in sequence, then, you can see six names under the UrlTemplate branch: "1", "2 "...... "6" string values: "www. % s.com", "% s.com", "www. % s.edu", "% s.edu "...... They are used to specify the auto-matching range of IE. If the majority of users want to add a new automatic matching function for IE, they only need to create two new strings, such as "7" and "8", under the UrlTemplate branch "), and set the value to "www. % s.com.cn "and" % s.com.cn "then enable IE to automatically identify the suffix" .com.cn. Of course, we can also use this method to increase IE's automatic identification of suffixes such as ". gov" and ". net.
10. Delete the underline in the webpage link

When we open an IE page, we will find that there is a line below the hyperlink, which makes it easier for users to distinguish the hyperlink from common text. But sometimes we don't want to see any dashes under these hyperlink to achieve a certain layout effect, but we want to cancel them, which is also very easy to do! In fact, IE also provides three different display statuses for underlines, they are "always show underline", "Never show underline", and "show underline when you place your mouse over a hyperlink ", the majority of users can adjust it according to their own needs. Specifically, if we want to set whether IE displays the hyperlink underline, start the Registry Editor for Windows 98 and expand the HKEY_CURRENT_USER \ Software \ Microsoft \ Internet Explorer \ Main branch in sequence, then we can see a string value named "Ancher Underline", which is used to set whether to display the hyperlink Underline. When the value is NO, it indicates that NO underline is displayed; if it is YES, it indicates that NO underline is displayed; if it is HOVER, it indicates that NO underline is usually displayed, put the mouse under the corresponding Hyperlink and show the underline. The majority of users only need to change it according to their own needs.
Note that the above method is used to modify the default value of the system. That is to say, the system will display the default value only when the website we browse is not set to show the underline, if the user browsed the website and set whether to display the underline, IE will display it according to the settings of the corresponding website.
11. prohibit others from accessing historical information

As we all know, Windows 98 has a history function, which can record various operations performed by users, such as the searched content, running programs, and browsed websites, then, we can retrieve the records directly from the same operation, so as to facilitate the use of the majority of users. However, there are two aspects to everything. Although the historical records can be used by users conveniently, they also bring about the possibility of leaks, some illegal users use these records to obtain the Web page information that we have accessed. To ensure absolute security, we need to take appropriate measures to clear these historical records. How can we clear the historical records that we leave when we use IE to access the Internet? Start the Registry Editor of Windows 98 and expand the HKEY_CURRENT_USER \ Software \ Microsoft \ Inertnet Explorer \ TypedURLs key value. This key value is used to save the IE history, it has a total of 25 records, saving the 25 websites that the user has recently browsed. we can delete the records as needed.
