ASP Error Messages Not Getting To The Client With IIS5.1 On XP Pro

I just upgraded to Windows XP Pro from Windows 2000 Pro. All my ASP stuff seems to work, except that when an ASP page generates an error, and the Error handling is set to "On
Error Goto 0" the page just stops, as if I typed a response.end, and no
error information is returned to the client. If I set On Error Resume Next,
and write err.desc after the offending line, the error text is written
correctly. For debug purposes of course it is nice to be able to
immediately see the line number, and description though.

Anyway, does anybody know what setting I need to change to fix this? I have
server side, and client side debug set, and I have it set to send detailed
errors to the asp page.

Another interesting thing is if there is a compile-time error, like a syntax
error, or something, the page doesn't load, but I get the error message
until an error happens with the above condition, after that, it will just
return a blank page.
