Nodes are not consistently configured with IPv4 and/or IPv6 addresses on network adapters that are usable by the cluster.

During cluster validation of a multi-subnet SQL Server 2012 Availability Group cluster, the validation report kept returning the following warning:

"Nodes are not consistently configured with IPv4 and/or IPv6 addresses on network adapters
that are usable by the cluster."

Below that entry was as follows:

Node <Server1> configured with IP addresses from protocol IPv4
Node <Server2> is configured with IP addresses from protocol IPv4 and IPv6

After comparing ipconfig /all and device manager (show hidden devices) entries on both nodes, Server2 included 4 Microsoft ISATAP Adapters, while Server1 didn't.

Shown here as already disabled
After a couple hours of research and verification that we aren't using IPv6 on our network, I disabled the ISATAP devices inside the device manager and the cluster was able to validate properly.

How to keep your remote desktop session active when it's minimized

If you have an interactive application running on a machine that you have open in an RDP session and you want the app to continue to run when the RDP session is minimized you'll have to make some changes to the registry on your computer (not the remote computer).

Original blog post

The general steps are to modify the registry by doing the following:

locate the key:


HKLM\Software\Microsoft\Terminal Server Client\


add a DWORD value in this key, naming it "RemoteDesktop_SuppressWhenMinimized", and give it the value 2.


If you're a 64-bit client, add that value to this key:HKLM\Software\Wow6432Node\Microsoft\Terminal Server Client\
