Thanks for a answer,
No solid answer, I seldom see such an effect.
One possibility, many services have a default config file installed with the service. They also may have a "local" config file that takes precedence if present. "local" may be done by location or by a specifice name variation.
If you are configuring your services by modifying the default config file, it may be overwritten by an update.
