You install Forefront Threat Management Gateway (TMG) 2010 on a computer.
You configure the primary IP address or the DNS address of a network adapter by using one of the following address ranges:
You open Forefront TMG 2010 Microsoft Management Console (MMC), and then you open the Networking node.
In this scenario, you receive one of the following error messages:
Error: 0xc0040446 - The specified IP address is reserved and cannot be used.
Note You receive this error message if you configured the primary IP address.
Error: 0xc004041d - This network adapter DNS address is not defined using a valid IP address.
Note You receive this error message if you configured the DNS address.
This issue occurs because these address ranges are incorrectly reserved.
The Requests for Comments (RFC) 3330 is implemented and reserves these address ranges. However, the RFC 3330 is obsolete. Therefore, the RFC 5735 that allows for the usage of these address ranges is not implemented.
