急！asp用stream直接下载文件的问题

[kookies]

能够弹出文件下载对话框。可是为什么下载文件的大小才5k？原文件可是5M多呢：（
在我的机器上下载正常，放到外部服务器就只有5k。

我的代码：
Function downloadFile(strFile)
'' make sure you are on the latest MDAC version for this to work
'' get full path of specified file
strFilename = server.MapPath(strFile)

'' clear the buffer
Response.Buffer = True
Response.Clear

'' create stream
Set s = Server.CreateObject("ADODB.Stream")
s.Open

'' Set as binary
s.Type = 1

'' load in the file
on error resume next

'' check the file exists
Set fso = Server.CreateObject("Scripting.FileSystemObject")
if not fso.FileExists(strFilename) then
Response.Write("<h1>Error:</h1>"&strFilename&" does not exists!<p>")
Response.End
end if

'' get length of file
Set f = fso.GetFile(strFilename)
intFilelength = f.size

s.LoadFromFile(strFilename)
if err then
Response.Write("<h1>Error: </h1>Unknown Error!<p>")
Response.End
end if

'' send the headers to the users Browse
Response.AddHeader "Content-Disposition","attachment; filename="&f.name
Response.AddHeader "Content-Length",intFilelength
Response.CharSet = "UTF-8"
Response.ContentType = "application/octet-stream"

'' output the file to the browser
Response.BinaryWrite s.Read
Response.Flush

'' tidy up
s.Close
Set s = Nothing

End Function
