最近经常有人问在win2000和iis5中不显示asp错误的详细信息，而只显示错误号，如"错误id800xxxxx"，这使得程序调试很不方便，有些人采取在iis中设置500-100错误指向默认，这样做也不会出现详细的错误信息。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:
<%@ 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
%>
