Re Format Workstation and Re Install Windows had similar issues with different flavors of windows that came pre-installed from Dell and HP. Brand new systems but had issues.. Did not worth the effort to figure out what changed in Microsoft OS, if Adagio works on some desktops, clone one of those PC and deploy..If ALL did not work then it would be an issue... The fact that you, like me have to work alongside (IT Guys)- Network Administrators, let them fix the PC so that it will connect .... It may be a Microsoft BUG ...

Finally - RE-Boot the SERVER...
