Disk Image Package source not editable - Access package from a specifically set up package server

Hi Folks,

In DS 7.1 a customer of ours has created a package. After creation another administrator logs into the console and tries to edit the package source. But he cannot edit it because it's grayed out. Same thing with Package location. There is also a mysterious entry in package source. "Access package from a specifically set up package server". You cannot set this manually to other packages because it's not an option. Furthermore it's not documented in help. Does anyone have a clue what this is supposed to mean and why the setting could be grayed out?

Thanks in advance!
