In order to enable the Unit staff timely understanding of the instructions of the superior and the unit notice and other information, the unit leader decided to build in the LANWebserver, to ensure that the LAN -Common workstations can be successfullyWebaccess. Received the leadership request, the network administrator immediately chose a hardware performance quite good computer, installed aWindowsServer2003system, and in which the erection of theWebServer;to ensureWebaccess speed, the network administrator willWebthe server is connected to the same switch at the same time as the normal workstation in the LAN, and is guaranteed to be in the same working subnet directly. Usually, some of the common workstations are installedwindowsxpsystem, and some have installedWindowsVistasystem, but regardless of what operating system is installed, they can be quickly accessed to publish toWebvarious types of information on the server.

However, local area network users are doingWebwhen you visit, you encounter a baffling symptom: regardless of which type of system comes with theIEbrowser Access units published toWebnotification information on the server,Webserver systems are forced to enter user name, password information for authentication;in fact, the network administrator is not at allWebserver-side authentication settings, and when you look at the relevant settings, the network administrator discoversWebThe server system allows any user to access anonymous logins, what is the reason for the system to force users to log in??What's even more amazing is that even if the network administrator correctly entered the loginWeba valid user account for the server, or even a super user account for the corresponding system, will not be able to log intoWebserver, what the hell is going on here??is there a problem with the network line??or isWebthe server is not working properly?There are other unknowable problems ...

Test line Connectivity

In order to determine whether the line connectivity is normal, the network administrator first login into the switch backend management system, and the system to switch to the global configuration state, in this state to execute the " Disdia string command, from the switch diagnostic results information that is returned later, the network administrator sees that the switching ports on the switch are working in the up state, which indicates that the working state of the swap port is normal.

after that, the network administrator randomly tested the connectivity of several common workstations and found that the cables were connected.;simultaneous usePingCommand TestWebServer'sIPaddress, it is also possible to find the addressPingThe connectivity of the LAN network line is normal; Since the network line is unblocked, the client system accesses it in the default state .WebThe server should be normal, and now access is not normal, most of the problems appear inWebserver "Body".

Re-check the authentication settings

Now that the Login dialog box appears on the system screen, it meansWebThe server must have the authentication feature enabled at some point;To do this, the network administrator decides toWebThe authentication-related settings in the server are re-examined. Log in with system administrator privilegesWebServer System, open the system's Start menu, click Settings, click Control Panel, and from the System Control Panel window that pops up, double-tap the Administrative Tools icon, and then expandIISConsole interface, select TargetWebThe host name of the server, right-click the host name, and then click the Properties command on the shortcut menu to enter the targetWebProperties dialog box for a site;Click the Directory Security tab in the Properties dialog box, locate the authentication and access control location, click the Edit button at the corresponding location, and then in the Settings window that pops up, the network administrator selects the integrationWindowsauthentication, anonymous access, and so on, found that you still cannot log on successfullyWebserver, and then cancels the selection of these settings options, but no matter how it is set, the above symptom still exists.

later, the network administrator found Web server's home directory, open the corresponding home directory of the Property Settings window, go to the window's "Security" tab page, the results see that the directory allows any user access, it is clear Web failure of server access failure, regardless of authentication settings.

Try adjusting the licensing mode

because any account entered cannot successfully access the published toWebunit information in the server, the network administrator begins to suspectWebServer Licensing mode may be a problem, so immediately search for relevant information on the Internet, and sure enough, the online licensing mode can cause the wrong accessWebthe server's symptom. See this prompt, network administrator conquered, over Boots, immediately openWebThe Start menu of the server system, from which you expand the Settings, Control Panel window, double-click the Authorization Feature icon in the window, open the Licensing Mode Settings dialog box, the network administrator sees the targetWebThe server system uses the Per Server licensing mode by default, while discovering that the number of user connections is set toTen", it is clear that such a setting would likely result in the entry of any account that cannot be successfully accessedWebServer Failure Phenomena;To do this, the network administrator attempts to targetWebthe server's licensing mode is adjusted to the "Per Device or user" option, and then the "I agree" option in the Per Device or per Customer authorization box is selected, which originally thought to rebootWebthe server system can solve the problem, but in fact the server licensing mode adjustment does not play any role at all.

Address conflict implicated access

in the attempt to adjust the various possible settings are not the case, a user in the local area network suddenly call to help the network administrator, said that they new put into use a printer, after setting up the network print status, not long after, it will not print properly. Hearing such a fault description, the network administrator in the mind immediately flashed a hint of the idea that the network printer affectedWebthe working state of the server?try to hold the mentality, network administrator immediately to the network printer site, log in to the Network Printer Management page, check the relevant network settings parameters, the print log page unexpectedly indicated that there isIPAddress conflict phenomenon;further check for conflictingIPaddress, the network administrator suddenly dumbfounded, the conflict of theIPthe address is actually in the unit LANWebThe address used by the server host, it is no wonder that LAN users cannot successfully access the unit'sWebserver.

Originally, the network printer in order to facilitate user management and maintenance, in the default state is also enabled to run aWebServices, print users can log intoWebmanagement interface, to remotely modify the various printing parameters, only the network printer automatically runWebThe service does not allow anonymous access. When the network printerIPaddress to rob the unitWebafter the host address of the server, the Internet user will visit the unit again laterWebserver, you may be accessing the network printer'sWebAdministration page, which does not allow users to access anonymously, the authentication window pops up on the system screen, where the network administrator enters the targetWebany user account in the server, of course, cannot successfully complete the logon operation unless the user account and the login target of the network printer are logged onWebthe server has the same user account.

after finding the specific cause of the failure, the network administrator adjusted the network printer used in the unit LANIPaddress to ensure thatWebserver hosts use theIPaddress has not been illegally robbed, and then restarted the unit'sWebServer host system, this time no longer let the network administrator disappointed, the client system re-try to access the unit'sWebserver, you can access all kinds of information normally,Webthe failure of the server access failure is completely resolved.
