Route mode sharing Internet frequently removed line Q: Use ADSL sharing Internet access: Use a broadband router (TP-LINK TR460) to connect two machines to automatic connection, instantaneous drop in the Internet (once every 20 minutes), View Routing System Log Specific Tips: "Receive PADT, the server is required to disconnect this connection." There is no such thing as "cat" without a router. How to solve this problem? A: From the problem, it is estimated that there are two questions: First, the router settings, in which the router settings are automatically disconnected if the line is idle within a certain period of time. If this is this problem, set "Yongxing" in your broadband router. Another problem should be a telecommunications to limit the network by binding the MAC address). You can use your ADSL MODEM's MAC address "clone" to the broadband router. File sharing response is too slow to ask: When using HUB Internet access, the file sharing between each other can be smoothly performed. Since the use of the router, my machine can see the shared file in the network neighbor, but can enter other machines, but Drag the file shared into my machine is not the response is the speed of the speed, what is this malfunction? A: "Other machines are always shared", indicating that your network and hardware are no problem, and the fault should appear on the end of your machine to the router port. This part is: Troubleshooting, NIC, network cable, port of switching equipment. Use the way to change to resolve: 1. Check if the line sequence and the network cable itself have problems. 2. Try the network cable on the other port of the switching device. 3. Check your machine, network card driver installation, set whether it is normal, does the firewall software are installed, whether the software is faulty operating system and settings or other programs, in addition, check if there is a fault to solve the method to solve it. Also check the settings of the BIOS. 4. Check the network card of the faulty machine to see if the NIC has a compatibility issue. DHCP service subnet mask assignment Q: I use the ADSL broadband Internet access, use the router and then pick a 16-port switch (DHCP assignment IP), recently there are several machines to always have a local area network, but I can access the Internet, use ping After the command, IP and gateways are correct, only the subnet mask is different, 255.0.0.0, these two computers that cannot be connected to the LAN are the same situation. How to solve this problem? A: The subnet mask is different, and it is not accessible to each other. Your problem is that DHCP does not have an IP address correctly for a computer in the LAN. This should be caused by your DHCP settings. First, the DHCP server must have a static address, and the subnet mask should be what you need (255.255.255.0 in the text), when you create a scope, you want to set the assigned address range, subnet mask, gateway , DNS and other parameters. Please check the DHCP server or router in your network. If you use its DHCP service function, see if the setting is correct. In addition, it is also necessary to check if there are other DHCP servers in the network at work, have other DHCP servers exist, shut down the DHCP you are using, see if the DHCP client can get the address, if it can, explain other DHCP servers . The implementation of the load balancing of KTV catalog system: Can the KTV song system can be implemented with network load balancing technology? A: This is very easy to implement. The main methods are as follows: 1. If you do load balancing with three computers, your song interface is estimated to be similar to IE.
Install IIS on each machine, install the song system, each machine IP is in the same network, but cannot be the same, if set to 192.168.1.1, 192.168.1.2, 192.168.1.3. Each song system uses the address and mapping of the relevant service settings of itself. 2. Enable network load balancing function on each computer, and set the network load balancing address of 192.168.1.5. 3. On each client, you can use 192.168.1.5 to log in. Network load balancing technology automatically forwards requests from 192.168.1.5 to different machines. Reply

Accessing the web server To enter a password Q: I set up a web server (using IIS), but when you browse IE, you have to enter your password every time. What is going on? A: Please open from "Program → Administration Tool" "Internet Information Services", click on "Computer Name → Site → Default Site", right-click "Default website (if you have newly established a website, click", click "Directory Security Sex "tab, in" Anonymous Access and Authentication Control ", click the Edit button, enter the Authentication Method dialog, confirm the" Anonymous Access "and" Allow IIS Control Password ", Cancel" Integration Windows Authentication "and" Basic Authentication (if selected). Return it after completion. Also, if NTFS access is set for the web home directory, it should be restored to the system default value, allowing Everyone to have read permissions. Concurrently accessed IP restrictions: Use the IIS erasure server, use the netstat -na command with the netstat -na command on the server, found a large number of HTTP requests (more than 500 connection requests), connect to this site 80 port, please teach what Good way to solve the problem: A: You can solve the problem on the IIS. From Administrative Tools, go to the "Internet Information Service", right-click the Select website, select Properties, go to the Directory Security tab, click the Edit button in IP Address and Domain Limits, Select "Authorization Access (Default)" in the pop-up dialog box, and then click the Add button to pop up "Deny the following access", select from "Type": 1. If you want to limit a computer, please select "Single", and enter the IP address you want to limit in "IP Address"; 2. If you want to limit a set of computers, select "A set of computers", enter the subnet network segment you want to limit in "Network Identity" In the "Subnet Mask", enter the corresponding value, if you want to limit the address of this network segment 111.222.1.1.1.1.1.1., Enter 111.222.1.0 after "Network Identity", enter 255.255 in the subnet mask. . 255.0. For example, a computer access to the network segment from 111.2222.1.1 to 111.222.1.222. 111.255 should be 111.222.1.0, and the subnet mask should be 255.255.255.0. Click the "OK" button to return. 3. If you want to limit a domain name, select Domain Name and enter the domain name you want to limit below. If you restrict the XXX.ZZZ domain name, you cannot enter www.xxx.zzz, and you should enter xxx.zzz. In addition, this operation is to limit the domain names on this primary domain, limiting all hosts in the XXX.ZZZ domain name, this operation requires IIS for a large number of DNS reflection inquiry, traffic is relatively large, do not use easy to use . Communication between different sub-networks Q: There are two computers in two network segments in A, B, and the A-machine IP address is 15.xx.xx.7, B machine IP is 18.xx.xx.10, two networks The internet has been connected to the Internet, and can be pinged to each other, I can make the B machine to connect the Internet without the Internet, and connect the Internet through the A-machine, if you can set? A: In the TCP / IP network In, only the computers within the same network segment can communicate with each other. The gateway is an exit that connects another network segment.
That is, a computer must be implemented by means of a gateway if you want to communicate with other networks (including the Internet). Normally, the gateway communication involves two IP addresses, one is the IP address of the local network, one is the IP address of the remote network, and the communication between the two networks is routed or converted by the gateway. Since the computer of the B network segment cannot access the IP address of the A network segment, even if the computer of the B network segment is set to the gateway of the A network segment, the gateway will fail, resulting in failed communication, thus making B network segment Computers can only access the local network. Therefore, the gateway must work with the workstation in the same network segment. Breakthrough in the upper limit of the domain account: Server and workstations are Win2000 systems, and the workstation is prompted "" The maximum value of the computer account allowed to be created exceeds the domain, reset or add limited value ", and the computer account on the domain has only About 30 days of validity period. How to solve this problem? A: Open the Control Panel window, double-click the "Authorization" icon, display the Select Authorization Mode dialog. Select "Each server ..." radio box, click the Add License button to display the New Customer Access License dialog. Add a suitable number in the "Quantity" text box. If there are 100 computers in the network, you can add more than 100. Of course, the more users are, the more system resources, and it should be confirmed to be authorized by Microsoft. Then click "OK", "I agree". The settling cost of the thick cable network is asked: Under the premise of transmission distance exceeding 185 meters, ADSL can be connected with a thick cable. Excuse me, how many rice transmission distance can you support? How much is the price? Can you replace it with fiber optic line? A: The thick cable supports up to 500 meters. Now the price of the thick cable is about 1 to 5 yuan / meter. The cost of the fiber is similar to the thick cable, but the fiber is converted to the RJ45 network cable, and the transfer device is relatively expensive. When the network bandwidth usage is not high, it is preferred to use a thick cable (low cost, easy). No Network Can Configure Activity Directory: Do you configure Windows 2000 Server Active Directory? If you can, how can you configure it? A: If you have a network card on your computer, it is not connected to the network. It is possible to configure an active directory. However, if you don't have a network card, you cannot configure the activity directory. However, the following methods can be made: 1. Install the virtual network card provided by Microsoft. Double-click the Add / Remove Hardware icon in Control Panel, run "Add / Remove Hardware Wizard", select "Add / Exclude Equipment Fault → Add New Equipment → No, I want to select hardware → network card from the list", manufacturing Merchants choose "Microsoft", the NIC selection "Microsoft Loopback Adapter", install the Microsoft Virtual Net Card. Then, set a static IP address for the network card and set the DNS address to your IP address. 2. Install the virtual machine. If you want to do network-class experiments on a computer, such as active directories, add domains, DNS, DHCP, etc., just install a virtual machine software --vmware workstation, even if you do not have a network card, you can also build a network environment, complete Various network experiments. return

ADSL device CRC error Our bedroom computer is connected to the Internet in ADSL, and it is often turned off. When you enter the ADSL MODEM management interface, sometimes the data transfer rate is very low, and the number of CRC errors uploaded time has reached more than 3,000 (the previous value is basically 0). The line attenuation has reached around 20, and the computer that installs the same ISP broadband is normal. May I ask what is the reason? Virtual Dial Protocol Error The operating system is Windows 2000 Professional SP4, using the RaspppoE 098C dial-up software using the FTTX LAN. After reinstalling the system, there is a phenomenon that often has a svhost.exe file error. In the management tool, you can see that the error source is iPnathLP and Service Control Manager, and event code is 7031, 7002, 7009, 30013, 7000, 7009, respectively. After an error occurs, you can't access the Internet again, only restart. What is this caused by this? Is there any way to fix it? ASP services frequently stop our cell's server for Windows 2003 IIS CGI, Web, FTP and other services, and recent ASP services often cannot access. Ping When each machine of the DNS server accesss the Internet server, you will appear in the log file, and the ID is 1000. Checked the Microsoft Database, saying that the DNS error sharing Internet MAC address conflict school server's operating system is Windows NT, assigns an IP server to send a DHCPDiscover packet through the DHCP user through the NIC MAC address, the server receives the backward At that host, it provides a valid IP address that has not been assigned yet. However, some users can get the same Internet authority by modifying the MAC address to obtain the same Internet authority, but very unstable. When IP address resources are tight, share the Internet and unstable, what is the solution to solve? There is no route to implement a network card with a Windows 2000 Server machine installed a dual network card, which is connected to the A broadband and B wideband. After the Windows 2000 Server comes with the "network router" in remote access, the two network segments can be interoperable, but there is a problem that is always unable to solve: Because the A broadband and B broadband have IP limitations for the other party, Do not allow each other's users to access their own video resources, if you want to see a broadband video, you must disable the network card to connect B broadband; vice versa. Under Win2000 / XP, modify the MAC address, before the report has been introduced to modify the MAC address of the NIC by modifying the registry under Windows 98 / ME, but the key value cannot be found under Windows 2000 / XP. Ask, how do you change? return
