Reporting Service中遇到的一些错误及解决方法

情况1.
错误文本如下:
System.Configuration.ConfigurationErrorsException: Could not load file or assembly 'Microsoft.Web.Extensions, Version=1.0.61025.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35' or one of its dependencies. The system cannot find the file specified. (X:\www\web.config line 29)
如图:

造成这种情况的原因是由于web.config文件中有Microsoft.Web.Extensions这个文件没找到,应该是System.Web.Extensions

情况2.
错误文本如下:
The report server cannot decrypt the symmetric key used to access sensitive or encrypted data in a report server database. You must either restore a backup key or delete all encrypted content. Check the documentation for more information. (rsReportServerDisabled) (rsRPCError) Get Online Help The report server cannot decrypt the symmetric key used to access sensitive or encrypted data in a report server database. You must either restore a backup key or delete all encrypted content. Check the documentation for more information. (rsReportServerDisabled)

这个是由于密钥出错,只要在reporting service配置工具中,加密密钥中删除旧的,然后按"更改"按钮,就可以了.
