We are running a windows 2008R2 domain environment. i am running into a problem where clients that have two records in DNS (one for wireless and one for ethernet) are failing to update. What happens is when a laptop is connected to both wireless and ethernet then the ethernet is disconnected, the record in DNS for the ethernet connection doesnt go away. This causes server initiated connections to the client to periodically fail as the server (in this case our SCCM 2012r2 server) tries to connect to the ethernet interface which is disconnected.
If I manually delete the record for the client ethernet connection, everything starts working.
