Solution: In the IIS application configuration, check the extension mapping settings to check the file If there is a ", then no such exception information will be received. It is estimated that IIS and the application handle the 404 error. The user access first requests the relevant page through IIS. If the setting is not set, the IIS does not judge and directly submits it to the application for interpretation, but the access is This file does not exist, nor does it set the relevant interpretation rules, thus causing the application to be abnormal and writing the exception information to the event record. For example, to configure a pseudo-static .html mapping, the html file does not exist and needs to be interpreted and executed by the application. In this example, the extension is .asmx. For the time being, it is unclear how the access can cause this exception. At least I enter the non-existing access address in the browser and it will not cause event logging.
Solution: Start -> All Programs -> Ms Sql Server -> Configuration Tools -> sql server Peripheral Application Configurator -> Services and Connected Peripheral Application Configurator -> Open In the Database Engine node under the MSSQLSERVER node, first select "remote connection", then select "and use TCP/IP and named pipes" at the same time, after confirming, restart the database service.
