godaddy windows空间没有写入权限吗？

<%
Set FSO=Server.CreateObject("Scripting.FileSystemObject")
Set MyFile=FSO.OpenTextFile(Server.MapPath("data.txt"),8)
MyFile.WriteLine("写入内容")
Set MyFile=Nothing
Set FSO=Nothing
%>

以上代码在本地可以执行，godaddy上无法运行，提示The server encountered an internal error or misconfiguration and was unable to complete your request.
读写权限都设置过了，不知道问题在哪里
