Navision's Nettest tool

Does anyone know where one can get a copy of Navision’s Nettest tool, I have tried looking through and searching the MBS Partner Forum and cannot find it. It used to be issued with the product CD , but since you can download most versions of Navision from the partner site. I have not had a product CD in years. If anyone knows where or has a copy of the NETTEST tool please drop me line. Thanks Wendy
