SCCM 2012 in IPV6/IPV4 Mixed Network is slow

Scenario

SCCM2012 servers are located on a subnet with IPV6. The clients are on an IPV4 subnet. This is of course not best practice, but could happen during testing.

The clients try to connect with the “IPV6>IPV4 Tunnel adapter”, and eventually tries the normal “Local Area Connection” adapter. This happens every time the client tries to contact the SCCM servers, for example when the clients try to download applications or software updates. The software distribution may also freeze or hang.

In this screenshot, you can see the tunnel adapter tries to connect using IPV6.

The download has no progress.

Eventually it tries to connect using regular IPV4.

And the download starts.

The solution

Disable the “IPV6 tunnel adapter” if your server is running on a subnet with IPV6 and your clients on a subnet with IPV4 only.

You want to configure the registry as described in chapter: “5.E” in the following link:

This registry update is easily deployed with GPO.
