Not true...
In the setup environment I have, the ADS 1.01 Add-On is now unable to connect to a MS Windows 2008 64-bit Domain Controller (aka Active Directory server).
Without any changes to the Active Directory or Win2008 64-bit server, the previous ADS that came with firmware 1.04b3 works fine. After upgrade to v1.04 official and ADS 1.01, it refuse to work anymore.
I am now forced to run DNS-343 in standalone mode until more testing and troubleshooting can be done to determine the cause of failure.
Note: The entire forest of 4 domain controllers (2 on root domain, 2 on child domain) runs on Windows 2008 64-bit. Have yet to upgrade any of them to Windows 2008 R2 yet.
