When writing the .NET program, if you use Access to do a database, you often forget something, but make the database you can't access, and the report is not very direct. For example: performing an unrecognizable query. This is often encountered in the ASP. Exception, in ASP.NET. Depressed, have friends, help me solve such problems. The method of handling is very simple, should you say that there should be a big problem, but always forgotten, so on This, to help help .a: Your partition must be NTFS, you want to add a modified or write permission in the security attribute of the folder or database file in the database file, is yours. You want to modify the account of the database can't modify .mdb, may be the permission problem of that account, or it may be .mdb itself is read-only, if it is XP, right click on the folder properties where the database is located, "Allow other network users Modifying my files "before the check; if it is Win2000, you can add write permissions in the safeone in the security, only the ASP.NET write permission can also be A: Step: You can follow the following:
1. Click on the browser (the default IE) tool menu, enter the intenet option; 2, select the Advanced tab, find "Show friendly HTTP error message" to hook out (default is hit) 3, run your error ASP again Program, the browser will display the error message.
Then it is judged a problem.
Step 2: The IWAM account password is incorrect. The IWAM account is an built-in account that automatically established when installing IIS5, which is mainly used for Internet information services for applications outside the process. After IWAM account is established, it is used by the Active Directory, IIS Metabase database, and COM applications. The account password is saved separately, and the operating system is responsible for the synchronization of the IWAM password saved by these three parties. According to the constant, we are responsible for the operating system, we can rest assured that we don't have to worry about mistakes, but I don't know if it is bug or what is the reason for the system's password synchronization, the password of the IWAM account sometimes fails, so that the password used by the triplet IWAM account is not uniform. When IIS or COM application uses error IWAM's password login system, start IIS OUT-OF-Process Pooled Applications, the system will refuse this request due to password errors, resulting in the failure of IIS OUT-OF-Process Pooled Applications, that is Our "Cannot Run Server {3D14228D-FBE1-11D0-995D-00c04FD919C1}" (here {3D14228D-FBE1-119C1} is the key) of IIS Out-of-Process Pooled Applications If you cannot transfer to IIS5 applications, HTTP 500 internal errors are produced.
If it is not resolved, it is recommended to rean IIS or operating system.
