Let's assume someone has 5 different SQL Server instances running on a server. Initially all are using dynamic ports.
Is it safe to restrict one of those instances to use the static port 1433 while all others still use dynamic ports?
Normally, depending on startup order it could happen that one dynamic instance claims port 1433, so that the fixed port instance can't grab it later on. Would this possibly prevent the fixed port instance to run?
Or is there any internal mechanism in SQL Server that starts fixed port instances first, and dynamic port ones afterwards?
