This would seem to be what you're asking for

Random rand = new Random();
string hostName = companyName + departmentName + rand.Next(1000,9999).ToString();

It's better if Random rand = new Random(); is called once and not everytime you create a new hostName, because you want to avoid any possibility that 2 Random objects would have the same seed.
