You don't need any license files to get the analyzer back up and running, but you do need them for any of the optional tools that might have been purchased, such as Inverse Assemblers, Source Code Correlation, etc...
The license files are specific to each 16702 and can't be transferred.
Sadly, licenses files can no longer be created. The 16702B went off the price list in 2005, and support ended 5 years later, in August of 2010. Once support ended, the HP-UX systems used to create the licenses were shut down, disconnected, and recycled.
Can node locked licenses issued to PC Hosted 1680/1690 series using the agilent site be transferred to another PC in case of failures? I understand this is hostid dependent but I can't find a way to re-issue these in the license page using the entitlement certificate.
Nothing broken here, just want to understand how the licensing works.

Not officially, but if you know your Agilent contact, they may be able to help you.
Just that. They sit on a server, and get checked out when they are used. That way a company with a lot of systems can use a smaller number of licenses, and share them as needed. These are tied to a specific server. The checkout/checkin process can be automatic, and very short term, or it can be very long-term, in that a license can be borrowed, and the borrowing client can be disconnected from the server. The license stays with that client, until they are reconnected and the license is returned to the server.
Node Locked Licenses
This is what you have. The license is in a file and is tied to a hostid. If you change the hostid, the license no longer works. The hostid can be the disk drive id, or the LLA of the NIC, or any other non-changing id. If the LLA is used, then a dead and replaced disk drive will allow you to continue using the license.
This is used more by 'pure' SW tools. The license can be loaded onto a system and used on that system for as long as you want. When you are done, there is a way to disable it on that system and move it to another system, usually via a USB key. This can be done as often as needed.
When using a 1680A logic analyzer. Can it be remotely controlled by the Logic Analyzer application running in a PC and use the plugins licensed under that PC hostid?
Yes, the licenses must be associated with the machine that is running the GUI. If you run the GUI on the LA, then the licenses must be there. If you are running the GUI on a PC, in remote (also called "hosted") mode, the licenses must be on the PC. If you are using Windows Remote Desktop, or VNC, to control a remote LA, then the licenses must be on the LA.
