  错误|显示|原创asp程序出错后,错误提示不是很清楚明白,让人摸不着头脑,用下面方法看看有没有帮助(此法目前只适合处ADO错误外的错误)
步骤一,用编辑器打开c:\winnt\help\iisHelp\common\500-100.asp
将它另存为500-101.asp备份(以便日后恢复)
步骤二,将下面的代码覆盖500-100.asp原文件,保存退出
步骤三,创建新文件test.asp,添加如下代码
<% response.write now(1)%>,存盘退出
步骤四,在浏览器中输入localhost/test.asp查看结果

500-100.asp的新代码:
<% language="VBScript" %>
<%
  Option Explicit

  Const lngMaxFormBytes = 200

  Dim objASPError, blnErrorWritten, strServername, strServerIP, strRemoteIP
  Dim strMethod, lngPos, datNow, strQueryString, strURL

  If Response.Buffer Then
    Response.Clear
    Response.Status = "500 Internal Server Error"
    Response.ContentType = "text/html"
    Response.Expires = 0
  End If

  Set objASPError = Server.GetLastError
