In the use process of the local area network, if network setting is undeserved, can bring about network function to sell at a discount greatly, cannot produce the effect with due network. Author union work is real, undermentioned the analysis of a few kinds of breakdown reachs his to eliminate a method to make one brief introduction.
One, hard disk of reasonable configuration server
When the visit speed of the local area network is reduced, often can think of the equipment of " of alleged " bottleneck such as net card, switching equipment above all, actually the speed of server hard disk also is the main factor that affects network performance. Normally, it is under consideration of the need when installing hard disk two respects element: The hard disk of the server should choose rotate speed as far as possible hard disk of generous of fast, look. The server had better use SCSI interface hard disk. SCSI interface uses collateral transmission mode to send and receive data, the IDE that uses than common PC or EIDE interface should be gotten quickly much. If the condition allows, to network server array of installation hard disk gets stuck. Hard disk array gets stuck can relatively promote hard disk substantially read keep function and security. On SCSI interface, not equipment of low speed SCSI (be like CD - ROM) as common as high speed hard disk, otherwise the SCSI interface high speed of hard disk transmits function general to cannot be developed effectively.
2, reasonable match switching equipment and net card
Install switching equipment and the data that the net blocks to also can improve a network well to transmit function reasonably. The author ever was the port setting of a switching equipment mode of 100M full duplex operation, and check of net of a 100M was installed on the server, everything is normal after installation ends, but when data transmission amount is large, transmission speed becomes very slow. Discover this net gets stuck not to support pattern of full duplex operation later, instead of switching equipment port after mode of half duplex operation, breakdown disappears. The port of this specification switching equipment and the rate that the net blocks and working mode ought to agree.
Note: When the parameter that installs network equipment, want a foundation actual condition, make the equipment such as switching equipment and net card matchs the job as far as possible, cannot copy product manual completely.
Breakdown example: Some unit Qi of business of a Founder 3100 brands machine (its configuration is: Intel surpasses raise 600, the equipment such as 10MRealtekRTL8029(AS)EthernetNICPCI net card) , when getting online through in-house local area network, discover abrupt join not to go up, cannot login normally, but the machine can be started normally.
Means of settlement: According to breakdown phenomenon, suspecting above all is computer virus do mischief. Undertake poison is handled killing, did not discover any virus; Whether is share of analytic system network put in breakdown accordingly. Click the “ network " in " of “ Control Panel, examine each parameter the setting is proper, all install correct; Doubleclick " of the neighbour on desktop " net to search whole network system again, discovery has this plane number only. Command of executive “Ping192.168.0.1 " and “ search " computer command, also look for equipment of machine of the other inside the net such as the lead plane in be less than a local area network, this machine is searched to also was not found on lead plane; Check equipment of this machine hardware then then: Double skeining thread of net card and network. After removing reticle trouble, need to block breakdown to make further analysis judgement to the net only right now. Ordinal click equipment of → of system of → of “ Control Panel to manage implement " , examine a net to block attribute, it is “ this equipment works currently unexpectedly normal " . Try to switch on the mobile phone enter MS - DOS means, with “Scanreg/restore " the command restores backup to register a watch. The result registers watch editor RegistryChecker to show: “Systemrestorefailed" (the system restores to fail) .
