@george1421 Thank you for taking the time to provide such a comprehensive response.
Starting with the legal problem, the nature of Microsoft to make things more difficult than they need to be… I figure that most people/entities tend to buy computers with Windows preinstalled so as to ensure legality (OEM), so I have so far resigned my mind to having to create images for each machine. Where I encounter those with VLK then the golden image approach would be applied. This should be a way to ensure the applications on the respective machines are good to go. Yes it is going to be tedious but it is what it is until the clients see the value to them (if any) by going VLK. Correct me if my logic is wrong.
The technical complication as you have detailed it is very interesting. Firstly, putting in a dedicated machine on each LAN will initially have to be at our expense as these guys will need to see the benefits in action first. This a major reason for going the route of a laptop we already own that was heading to a closet anyway. Load a Linux desktop to the old girl and she would continue to have a productive life. It can also be used in other ways as a Tech Support machine. From what you have detailed, there is a known work around for any DNS issues so it could move from LAN to LAN without much challenge. They Type C connection would be a problem for this old girl as she doesn’t have a port. So that bring me back to good old USB - any advice to help address that? Also would greatly appreciate if you would advise further on the network modifications involved to properly boot target computers for imaging.
Thanks again for the help thus far.
