Error:
You should consider SQL authentication account for database ownership; then you don't have to worry about accounts coming and going, databases or instances moving to different servers, and your next PC name change. I have several systems where we use:
ALTER AUTHORIZATION ON DATABASE::LumZueeDB TO [sa];
Or if you want to change the owner to that local Administrator account, then it should be:
ALTER AUTHORIZATION ON DATABASE::LumZueeDB TO [ThinkPad-PC\Administrator];
Note:
LumZueeDB : name of database
ThinkPad-PC\Administrator: account
