My co-workers can't see my instances connections

Well I need a help about it... The reason of this post it's because I did a connection of SQL Instances on spotlight so... everything went well on Virtual Machine, I saw the monitors about database but when my co-workers log in on the same VM, they can't see the instances that I connected. When they open the spotlight software there aren't connections but when I open Spotlight in the same Vm but with my user I saw everything I did... Does anyone know how can I fix this problem ?
