MDT client still looking for old deployment share

Use MDT 2012 to push OS and apps to client, then I changed the deployment share name now unless I do a diskpart clean it keeps looking for old deployment share name

I want to run litetouch etc to do hard links USMT etc

I image centrally then send these units out

 I need the easiest way to allow them to find the right deployment share based on the bootstarp.ini settings I have for IP
