Permission error, FSO.CreateTextFile

[barandjelovic]

Platform: Win2000 Server, IIS 5

Here is the server javascript ASP code:
var fs = Server.CreateObject("Scripting.FileSystemObject"
var path = Server.Mappath("test.template"
var tf = fs.CreateTextFile(path, true); //(line 37)

Here is the error:
Microsoft JScript runtime error '800a0046'
Permission denied
/admin/master.template.new.asp, line 37

Can you please help me configure the permissions so that this page can save the files?

Thank you.
