Slave of old machine still on my IP address

I have a new machine and when I start my machine in the morning, I have two slaves. One for my new machine and one for my old machine. I have been told that this is a legacy issue, so can anyone tell me if this is so and why this is still happening? I can disable the slaves, but they come back. I am using Deadline 6.2, win 7 64bit. We are due to go to D7 soon, so is this still going to be an issue in that version as well? We have a lot of artists who have had new machines and all have second slaves in their Deadline flyout.

Thanks

If you upgrade to Deadline 7.2 you should no longer see this issue, but yes it will still be an issue in Deadline 6.2 that you are running.
