Weak current College】 【Web server failures of strange why troubleshooting.

Accompanied on information requirements and continuous improvement, I believe most of the units will set up their own Web server, to Internet network unveiled information, publicity and self. In order to ensure that any Internet user can seamlessly access to Web server content, network maintenance in official announced Web information needs to be configured before you often look at IIS server in order to ensure the unit's Web site to be able to consistently stable operation. However many times, we will encounter Web server access failures of the symptom, in the face of the Web server failures, we tend to become flustered simply do not know that to get started, to deal with these Web server failure. Originally, the Web server failures caused by many factors, we need to perform troubleshooting, one by one in order to efficiently process the corresponding Web server failure phenomenon.

Web server fault symptom

In order to fully display units, expanding units visibility, unit leadership requires network maintenance, immediately took out the programme, the establishment of a character in the character of the Web site, not only ensure the unit's internal staff to resolve intranet normal access to the Web site, while also ensuring extranet users are also able to high-speed access to the site content. In accordance with the directives the leadership network maintenance staff to pick up a computer running performance particularly efficient computer as a server system, including installation, configuration, the application of the system, and WindowsServer2003 the system comes with IIS components set up Web server; in order to improve Web site performance, network maintenance has to be the same computer as the Web site directly to the unit Gigabit core switch, the destination host's IP address is configured with the units of the General staff by computer is similar to the address of a network segment. Beginning of time, whether intranet user, still outside the network users, all users are properly access unit's Web site.

However, not long, flat network users to access the Web site, you have access to the Web server failure failure, more performance-no matter from which a client system, use intranet address access units of the targeted site, the system screen will pop up an authentication dialog box, enter the requested unit staff have access to the account number and password, but when network maintenance workers try to Web site maintenance status of the system perform the login action, always login will not go; even more of a feeling that cannot be ignored is that the network maintenance personnel arrived at the scene of a Web server, see security configuration, the target Web site is that it has no enabled logon authentication configuration, the authentication dialog box pops up what?

Web Server troubleshooting

As a result of such factors Web server failure, we must have to perform on a range of possible factors, in order to troubleshoot to find detailed Web server failure causes and remedy to the targeted approach to high-speed processing failure phenomenon:

Web Server troubleshooting process 1, testing secure login configuration

Thought to access the target Web site, the system has an authentication dialog box pops up, which means that the target Web site may lack in the security log is configured correctly, causing users to access Web content, you must enter the access account. According to this analysis, network maintenance staff is ready to test your Web server's secure login configuration parameter, see the configuration can not correctly; think of it, network maintenance immediately came to the target Web site host to privileged account login, and click the "start"/"configuration"/"Control Panel" option from the pop-up system control panel window, locate the "maintenance tools" feature icons, and double-click the icon option, enter the corresponding system maintenance tools list window; then double-click IIS feature icon popup corresponding system of IIS console window, from the list on the left side of the window, locate the target region Web site is located in computer name, right-click the computer name from the pop-up menu in the implementation of the "property" command, pop-up target Web host properties configuration window; in the properties configuration window click on the "Directory security" tab, open the directory security options configuration page; the following, in the configuration page of the "authentication and access control" in the configuration item right, click "Edit" button, enter the authentication and access control configuration dialog box, network maintenance personnel found that one of the "anonymous access" and "integrated Windows authentication" and other options are selected, so he tried to withdraw these parameters option selected, and then again from the intranet of a computer to perform Web access, but similar symptom persists; therefore, the network maintenance again by selecting the "anonymous access" and "integrated Windows authentication" and other options, but let him feel particularly disappointed that the above two options, either select still not selected, like symptoms are present, this indicates that the target Web host security login configuration and the above symptoms and no contact.

Web Server troubleshooting process 2, testing directory access permissions

Is the target Web site points to a home directory on the user's access permissions to perform a qualified? think in building the FTP site, if not the FTP site home directory and open the user access permissions, then the average user cannot login to be IE reader FTP site; to this end, the network maintenance immediately open the destination Web site system resources maintenance window, find the corresponding main directory, use the right mouse button to click the home directory from the shortcut menu to perform the "property" command to open the corresponding primary directory properties configuration dialog box; click on the "security" tab, network maintenance, see which did everyone account access is not authorized to perform everyone account, resulting in a loss of Web server accessThe defeat of the symptom? in order to verify that such speculation cannot correctly, network maintenance immediately click Security options configuration page in the "add" button to add the Everyone account to the account list, and at the same time as the account is configured with the appropriate access permissions, the end click OK button to perform the configuration save operation, thought this configuration can handle queries, but network maintenance retry from ordinary client system Web site access operation, still not successful, it is clear the symptom of factors might not be a directory access permissions.

Web Server troubleshooting process 3, test Internet connection configuration

Since login configuration and permissions configuration, can affect Web server access failures of the symptom, that question may play in other locations. Thought to the unit's Web server since the build is successful, the network maintenance crew seldom goes to change it, then the server's own doubts about the possibility of a relatively small, so the network maintenance decisions from common client network connection configuration to see if I could is client itself causes stir up.

Network maintenance workers fear that there may be a local area network, the ARP viruses resulted in ordinary client system to access the destination Web site, the Internet packets were forcibly forwarded to another host, so he immediately login to units of local area network core switch background system, and to use the system comes with diagnostic commands on the network every Internet ports perform the scan, diagnostic, results found that all the Internet port for operation is normal, and intranet network does not exist by ARP virus stir up address conflict, this indicates that the intranet network ARP virus does not exist.

Then network maintenance and on a few regular client system's network cable connectivity to perform the test and found that their status is normal, and from the client system to perform the ping command to test the target Web site IP address connectivity, it is normal, this indicates that the normal client system is able to correctly access the target Web site.

Later, the network maintenance worries about client system uses a proxy form online, because LAN use this form to access the destination Web site, you must first enter the proxy server logon account and password, so let's do the Web site access operation, the system screen pops up an authentication dialog box, for proxy? to exclude such factors, network maintenance immediately open client system IE Reader window, click the "Tools"/"Internet Options", open Internet options configuration dialog box, click the "connection" tab, and in the corresponding label configuration pages, network maintenance personnel found that local client system does not enable proxy server configuration, this indicates that the Web server access failures of fault and the client system's Internet connection without any contact.

Web Server troubleshooting processes 4, inspection authorization mode configuration

Troubleshooting the client system itself, the network maintenance once again the focus to the Web server. Experience Internet consulting related questions, network maintenance estimated WindowsServer2003 Server system authorization mode may be only modified, because the server licensing mode if the configuration is not very likely to occur at that time, no matter what the user logon account have entered is not valid for symptoms. Think of it, network maintenance immediately log into the Web server system, click the "start"/"configuration"/"Control Panel" command from the Control Panel window, double-click the "authorization" icon, a pop-up authorization mode configuration window, where network maintenance staff found the target Web site currently uses "per server licensing mode"; in order to determine the parameter can have an impact on Web access, the network maintenance will be licensing mode to modify in order to "every equipment or users" option, and restart the Web server system, however, this adjustment does not yield any results, it appears that the licensing mode configured on the Web access operation does not have direct effect.

Web Server troubleshooting process 5, inspection and other Web services

Experience the above troubleshooting, network maintenance personnel to confirm a Web server and the client system's own status is normal, flat network of lines is good, why the client systems must be in access unit Web site, the authentication dialog box pops up, and no matter what user account entered vain? experience dissect, network maintenance estimates for local area network may exist other Web services, and other Web services happen again Rob spent unit Web site address of the server, the end result a unit staff in implementing Web access, you are actually visited the other one without going through the correct configuration of the Web site.

Legitimate network maintenance staff ready to troubleshoot LAN should be can't exist other Web service, a faulty phone suddenly hit came in and said units newly bought printer suddenly doesn't network printing, then the fault is with the Web server access failed in what will certainly contact? think this, network maintenance immediately rushed to the scene of the network printer, login into the equipment maintenance page of the background, checking its configuration parameters, the equipment of the log page prompts that exist address conflict, look closely, the network maintenance staff found that conflict is actually the address of the Web site address units, are we from intranet client system access to the target site, access the printer background maintenance system? since there address conflict, network maintenance immediately began as a network printer to reallocate a address, he once again on the destination Web site performs access operation, this a very successful open the corresponding site content, it is clear that Web server failure phenomenon has been successfully processed.

Summary Web server failures

Experience more in-depth testing, network maintenance personnel found the printer equipment default runA Web service, then print the user will be able to resolve Web forms for printing equipment perform remote maintenance; and default network printer does not have to enable anonymous access, so when a network printer using the unit IP address of the Web site, the Internet user should have access to a printer background maintenance page and that page is required to perform authentication, this is a normal user why access to the target site authentication dialog when ejected proclamation, and network maintenance due to enter the network printer authorized user accounts only occurs no matter what the user entered the account cannot successfully log in. This Web server failures of the main culprit is the cause.

Recalling the above Web Server troubleshooting process, we found that the Web Server troubleshooting was very basic, if we're able to pay attention to new in LAN add a network printer, then in perform troubleshooting time we might have been able to pay attention to the change will affect Web server failures. To this end, we will troubleshoot network problems, you should first observation network environment can exist, if a change, and then on the change in thinking and Lenovo launched targeted, so failure to deal with are not games.
