  <p><font face="arial" color="#000000" size="2" style="line-height: 25px">当IIS 
  5.0遇到一个在编译或执行 
  .asp档案时产生的错误时，它就会产生一个500;100错误。在预设的状态下，所有的网站和应用程式都会把这个500;100错误传送到预设的 
  .asp档案中。在这个500;100错误产生之後，IIS也会产生描述错误状态的一个<font face="arial" color="#3e80d7" size="2" style="line-height: 25px"><b style="line-height: 25px">&nbsp;ASPError&nbsp;</b></font>物件的例项。若需如何使用IIS嵌入式管理单元来改变 
  .asp档案，进而处理500;100这类错误的资讯，请参阅《Microsoft Internet Information Services 
  5.0超级管理手册—网站管理篇》第3章〈伺服器基础管理〉中的〈启用ASP错误处理〉 。</font></p>
