How to resolve dual Nic conflicts

Now there are more and more friends with two computers, and broadband is gradually popularized. Maybe everyone wants to build their own home network. Generally, it is the most common and simple way to achieve dual-host interconnection and sharing of resources by installing dual-nic on a single machine, which is much cheaper than the solution to buy a router. However, because the system now has many boards and peripherals to load and sometimes resource conflicts are inevitable, it is learned how to adjust the machines with dual NICs:

1. Board replacement slot debugging resource conflict

When I first purchased a computer, there were few devices. Most people just inserted the PCI board into the slot and they could use it. IRQ conflicts often occur between NICs, modem, And the mouse. If dual NICs are inserted, windows may fail to be started or, A resource conflict occurs on the system device, prompting that the device cannot be enabled. Note: "This device lacks available resources. You must disable other devices to enable this network device ". At this time, do not trust the conclusion of Windows-I found that switching the card slots sometimes allows these conflicting accessories to "get along with each other ". However, due to the combination possibilities of boards in different slots, each time windows is started, the resources allocated for the Boards are different, and sometimes the driver changes a lot.ProgramThe information library is messy. Before debugging, you 'd better perform a backup on the ghost. If it is messy, mirror a new clean windows system for debugging. if it continues to be messy, sometimes an inexplicable error may occur when you connect to the original normal device, allowing you to take a detour. 2. Use two systems to balance resource conflicts

In different versions of Windows, the built-in driver libraries are different. Sometimes, you cannot load drivers or allocate available resources to some devices in an operating system, in another system, it may be another device. If you think inner cat is useless, it doesn't matter. If you think modem is needed as a backup, I suggest you use a dual system or multiple operating systems to balance the unsolvable resource conflicts, that is to say, in this operating system, some devices are forbidden to open the device you need. In another system, the opposite is true. In particular, windows and XP operating systems will intelligently install their own drivers on all the devices that can be identified, making it difficult to stop and uninstall them. Therefore, a relatively "dull" Windows 98 is added, sometimes you can load the necessary drivers as needed and select the desired device.

In addition, Windows automatically checks the current settings when configuring the network IP address and gateway. If you want to replace the two connections when a connection already exists, if the assigned IP address cannot be assigned to another IP address in Windows, it may be confusing. Therefore, before debugging the network, You 'd better back up the operating system and adjust it, otherwise, it is difficult to recover to normal.

3. Stop the installation after it is installed.

Even if the network adapter and modem conflict cannot be reconciled, you must install the network adapter. You cannot leave an unknown device because it still occupies resources. Generally, after the installation is complete, disable it to restore the previously abnormal dialing to normal. In addition, if you do not complete the installation, every time you enter the Windows system, you will be reported to find new hardware, which will make you tired of installing the driver.

Note that every time you install a hardware or make major changes to the system configuration, Windows usually requires you to restart. Many of my friends wanted to restart after installing all the software and drivers. This habit may need to be changed when configuring dual NICs. In addition to allocating IRQ and memory available resources to network devices, windows also needs to Configure Ports and IP addresses, if a device is not yet installed, it may be "overwhelmed" when Windows allocates these resources to it, especially in Windows 98, IRQ sharing is poor, it is better to restart it honestly; XP and 2000 will be better, but it is better to restart insurance. After all, if you do well, it will be done once and for all, and now there is no trouble at all.

4. Nic speed and connection Cable Problems

Many people started to have no dual network card online plan, but they only needed to buy a new machine, so the network card they bought may be different. In this way, when networking, you need to consider the problem that a 10/100 M Adaptive Nic is sometimes connected to a 10 m NIC-during external connection, 10/100 M Nic and 10 m Nic do not matter, however, when the two machines are interconnected internally, the connection may fail to be pinged, or the connection is normal, and the client cannot browse the webpage, this error occurs when two NICs exchange data packets at different rates. Of course, this connection method may not always cause such a fault, but when you find it, you need to check it. You can connect the 10/100 M Adaptive Nic to an external line, use a nic at the same rate as an internal connection.

It is worth noting that, even though the system passes the test by using an instrument, it may not allow you to achieve dual-host interconnection, because the instrument does not consider the Jumper and connection method, the author began to connect to the Internet to let people do a line, this is the case, the instrument passed, but the actual connection is not available, and finally carefully check, you can do it again (for example, in the following order: Yellow-earth, blue-earth, red-earth, white-Earth, to truly connect the two NICs, the last line must be called, that is, to convert the white-ground to the ground-white ). You 'd better use Windows XP or 2000 to connect to the Internet. They can display the network connection status and icons. When there is a cable problem, it will tell you that the cable is not plugged in; and Windows 98, it's hard for you to judge. In addition, if the internal network is not disconnected before the client is shut down, the shutdown may be extremely slow or even unresponsive, And the NT System can easily disable the connection, XP also provides the Network Wizard backup function, that is, to generate a backup file for the network settings on this machine, so that you can call other computers with the same task configured at any time; windows 98 is a lot of trouble. This is why Windows2000 and XP are much better than 98 on the network. Many network-related details have been taken into consideration by the NT System, although the size of 2000 and XP is several times larger than that of Windows 98, the mainstream hard disks are now 60 and 80 GB. Considering the completeness of network functions and the automation of settings, it is worth upgrading.
