[Solved] NLA Domain Profile and Disabled IPv6 on Windows Server 2012.

May 19th, 2013 by Andrea Matesi 4361 Views

Hello all,

today I experienced a Windows Server 2012 issue which puzzled me for a couple of hours.

After deploying a DC, I went on and disabled IPv6 (by adding the "DisabledComponents"-Key to my Registry):

reg add HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\services\TCPIP6\Parameters /v DisabledComponents /t REG_DWORD /d 0xffffffff

After rebooting the System, I noticed the Network Location Awarness-related "Domain" Profile wasn't loading (I noticed it 'cause I was unable to successfully Remote-Desktop-login to the DC since the "Public" Profile was ON!).

To preventy this from happening again, I went through the following Ace Fekay's article over the net: https://msmvps.com/blogs/acefekay/archive/2010/05/27/how-to-disable-rss-tcp-chimney-feature-and-ipv6.aspx

  • ...and I choose to setup my Registry to "Prefer IPv4 over IPv6":

reg add HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\services\TCPIP6\Parameters /v DisabledComponents /t REG_DWORD /d 0x20

By so doing, during my next reboot, my DC successfully loaded the NLA "Domain" Profile (&& I was able to successfully login to it thru RDP...).

Thanks Ace!
