实际上这可能是微软出于安全考虑而在500-100.ASP中没有显示详细出错信息。其实，你只要把500-100.ASP稍加修改就可以了。下面是我修改的这个文件的内容。你只要把他copy下来存为500-100.ASP然后覆盖原来的这个文件就可以了。注意文件中两行横线之间就是我修改的部分。
500-100.ASP:

Const lngMaxFormBytes = 200
Dim objASPError, blnErrorWritten, strServername, strServerIP, strRemoteIP

Response.Clear
Response.Status = "500 Internal Server Error"
Response.ContentType = "text/HTML"
Response.Expires = 0
End If
Set objASPError = Server.GetLastError
