We have several staff who may switch computers in different classrooms whose default printers may erratically change. Our GPO's are split so certain computers fall in different areas of the school - i.e in the east areas they have different deployed printer GPO's than those in the west.
Some staff may only stay using say 1-2 computers in the west areas, yet their printers might change to some in the east. In some cases they default to OneNote. We have no GPO's specifying default printers so I'm at loss as to why their Default Printers are now changing - especially with staff who have an office beside their classroom and always use the same default printer.
Any ideas as to the cause?
