if I recall correctly, services.ora belonged to the pre-grid-control oracle intelligent agent, where it kept the services it has discovered.
Recently, I've had the same experience with an Oracle DBMS 10gR2 on Win2k and apart from listener.ora and tnsnames.ora (sqlnet.ora, in case) I did not change any files; system is running on production since a couple of months without any problem; I don't remember anything about services.ora: what is this file for ? (sorry for ignorance).
A completely different matter is in case of an Oracle Application Server: I've never nedeed to change an hostname with AS but it seems to me it's not a simple (or even possible) task.
