T C P / I P and I N T E R N E T Introduction Windows 2000 Implementation of T C P / P is an important point-to-point link to the interconnection of Microsoft Wi N D O W S and U N i X. In order to thoroughly understand the network parameters contained in the Windows 2000 registry (and the correct value of these parameters), it is necessary to fully understand the basic network structure. The in-depth discussion of online background knowledge is exceeded in the scope of this book, but some important content provided in this chapter can enhance the work efficiency of Windows 2000 system administrators. I will introduce the network protocol, T C P / I P architecture, and D h c p on the M i C R O S O f T, which can have a context environment when learning the direct solution after learning. MS Windows Network Protocol Microsoft Wi N D O W S Network You can use a variety of network protocols, including T C P / IP, N e T B E U, A P L E TA L K, I P X / S P x, P P, S M b and D e c N e T. The ability of a server use protocol communication depends on which protocol installed on the system. In fact, there is a special protocol process between Windows 2000 computers and other servers, which can convert an protocol into another protocol in real time. Important is: Remember that the network protocol is hierarchical. T C P / I P is the best example of how the network protocol is hierarchical. 1. TCP / IPI P (I N T E R N e T Protocol, i.e., Internet Protocol) is a protocol that is responsible for addressing and sending data from a computer to another computer. The independent technology called Transmission Control Protocol, TCP is located on the upper layer of I P, which provides communication based communication, supporting reliable, sequential data streams. Both of these two protocols are used to communicate with I N t e R n e t, usually written as T C P / I P. Assume a driver driving a car. Engine (IP) provides the power of the car on the road, but the driver (TCP) uses the car's control system (throttle, brake and steering wheel) from the A point to the B point, and with the network road (network cable), traffic lights and Road signal (router) interaction. No engine, driver can't act, no driver, the engine is meaningless. Therefore, this is the relationship between T C P and I P. 2. Windows SocketWindows socket is implemented by M i C R O S O f T, which is widely recognized, which is initially developed with U N i X. In most cases, Windows Sockets is compatible with U N i x, and is a form of communication between Microsoft Wi N D O W S network and U N i x network. The Windows Socket is located on the upper layer of several protocols, just like T C P located on the upper layer of I P. Windows Sockets can use the T C P / I P protocol, or one of several other protocols, including I P X / S P x and A P L e TA L K. 3. NetBeuin E T B E U i is usually an ineffective protocol. N e t b e U i was developed by I B M in 1 9 85, which was later exchanged with several other platforms (including Microsoft Wi N D O W s). Windows 2000 supports N e T B E U i to provide backward compatibility for other systems and computers, such as LAN Manager. If the Windows 2000 system is running on the token ring, and the route function of the token ring network is started for use in WAN, then N e t b e u i is routed.
4. A well-known pipe (NAMED PI P e) is located in several protocols, including the upper layer of S O C K E T, N E T, N E T, N E T, I P x / S P x. The pipe is a region reserved in memory to process information, usually in a manner of automatic processing. The process of creating a pipe is called a Pipe Server. The process of accessing the created pipe is called a Pipe Client. A well-known pipe is a pipe with a unique name. According to one or more protocols used to create a pipe, the name of the pipe can be composed of multiple elements (associated with the protocol). TCP / IP routing T C P / IP is a protocol used to pass information from one computer to another computer. It implements information transfer by packets (P A c k e t), and the data packet is a data set containing information and routing information that is actually transmitted. Routing information is used to guide the package from the source computer to the target computer. The packet is to reach the target computer. The following events will happen as follows: 1) The client is parsing the host name into an I P address with the D n S or W I n S server to establish a connection between a computer. 2) DNS or W I n S server query multiple information sources, convert the host name of the text form into binary I P address.
3) DNS or W I n S server Send binary I p address back to the client computer, which is usually a value in the Wi N S O C K function call. 4) The client computer uses the I P address obtained in step 3 and sends the packet to the next computer on the network, or the gateway or another machine thereof or another machine according to the network topology. 5) The next computer on the network determines if the I P address of the packet is itself. If so, it retains the packet and a confirmation answer. Otherwise, the packet is sent to the next computer until the destination is reached. The above event sequence is called routing. When the I P address is converted into a numeric address, it can be routed. Routing can be implemented using a gateway computer or a dedicated router, and a set of routing tables.
DHCPD H C P represents Dynamic Host Configuration Protocol, DHCP. D h c p allows temporary connections to computers on the network share dedicated I P address. When the network topology is reorganized, it can help the network administrator by reducing the workload of the Handmade the fixed I P address. DHCP features Similar to a special DNS (see the previous section), it can only be applied to very limited fields (usually small LAN or I NTRANET); DHCP server accepts hostnames like DNS servers, and within it Find in the database and return to the binary IP address. Useful of D H C P is that it optimizes the mapping between rearrangement hostnames and binary addresses, and the standard D N S and W I N s are not. Many other network topics also need you clearly understand how to use the registry to adjust the Windows 2000 computer. Before trying to adjust your computer, you should completely master the web basics of Windows NT / 2000 before adjusting your computer. There are many books on Windows NT network basics, some of which may prove that you are practiced in accordance with methods in a direct solution.

The S O c k e t system uses two values to allow direct data streams without affecting stream control algorithms. You can change these values like this to meet the unique local area network condition: 1) Open the Start menu and select "Run". Click the "Browse" button to start navigation until the root directory of Wi N D O W S2 0 0 0 (usually W I N N T) is found. Go to the S Y S t e m directory and find R E G E D T 3 2. E X E, select it to the dialog and click the "OK" button. The Registry Editor is launched, and all configuration units are displayed in different laminate windows, respectively. 2) Select "Window" menu item H k e y _ L O c a l _ m a c h i n e, its sub-window display. Maximize this window for use. 3) Locate the tree control using the left window to the System / CurrentControlSet / Services Provider / ORDER child. Click this subkey to select it, display its value in the right window. 4) Entries for positioning to value D e f A U L T R e c e i V e wi n D O W and D e f A U L T S E N D Wi N D O W. Use the D WO R d editor to change the two values to be greater than 8 1 9 2 can allow more data stream control; if less than 8 1 9 2 allows less data stream control because the noise of the local line.
Change TCP / IP Server Socket Buffer Assignment to improve performance
Windows Socket allocates a memory buffer for internal use. You can change the registry in accordance with the following steps, increase the amount of memory allocated and increase the performance of Wi N s O C K: 1) Open the Start menu and select "Run". Click the "Browse" button to start navigation until the root directory of Wi N D O W S2 0 0 0 (usually W I N N T) is found. Go to the S Y S t e m directory and find R E G E D T 3 2. E X E, select it to the dialog and click the "OK" button. The Registry Editor is launched, and all configuration units are displayed in different laminate windows, respectively. 2) Select "Window" menu item H k e y _ L O c a l _ m a c h i n e, its sub-window display. Maximize this window for use. 3) Locate the tree control using the left window to the System / CurrentControlSet / Services Provider / ORDER child. Click this subkey to select it, display its value in the right window. 4) Depending on the machine's memory capacity, you will be positioned to the entries of value I n i t i a l s m a l B u ff e r C O U N t, I n i t I a L M e D i m b u ff e RC O U N T and I n i t i a l A RG E b u ff e r C O u N t. Using the D WO R d editor to change the value of the large buffer to 0 to 1 0, the value of the buffer is 0 to 3 0, and the value of the small buffer is 0 to 5 0. It is suggested that the memory capacity of the small memory machine is less than 2 0 m B. The memory capacity of the medium memory machine is 2 0 m b to 1 2 5 m B. The memory capacity of large memory machines is 1 2 5 m b or more. Set the number of threads used by TCP / IP server WINS
W i N S is a large number of working threads to help them complete tasks. Set the maximum number of threads is "art" depends to a large extent on local conditions and resources. The maximum number of threads can only be set by modifying the registry: 1) Open the Start menu and select "Run". Click the "Browse" button to start navigation until the root directory of Wi N D O W S2 0 0 0 (usually W I N N T) is found. Go to the S Y S t e m directory and find R E G E D T 3 2. E X E, select it to the dialog and click the "OK" button. The Registry Editor is launched, and all configuration units are displayed in different laminate windows, respectively. 2) Select "Window" menu item H k e y _ L O c a l _ m a c h i n e, its sub-window display. Maximize this window for use. 3) Tree control using the left window is positioned to S Y S Y T E M / C U R R E N T C O N S / P A R A M E TET E R S. Click this subkey to select it, display its value in the right window. 4) The entry of the value N o f WR k T H d S is positioned. Use the D Wo R D editor to change the value between 0 and 4 0. Note that the default value of N O O F WR K T H D s is the number of processors on the server computer.
Change the process priority of TCP / IP server WINS
W i n s is also the same as a process with other processes. Changing its process priority sometimes helps network performance. The following describes how to change W i N s default process priority:
