We had a DMG in our Casper image that would populate the “Connect to Server” fields with often used server links. As of 10.12 there seems to be a problem I just discovered.
On the initial boot after the image, the server addresses are there. Upon a reboot, the address are all gone. Not sure what changed but have confirmed it is not an issue in 10.11.6.

Did something change? Are these being referenced in a different plist now?
