I would like to request an option within the service to be able to delay active scan domains from being scanned upon service startup. Being able to specify a delay of a half hour or a user specified amount of time would be preferred.
We have quite a few systems in our domain, and upon service startup this causes some slowdown on the system hosting the website until about 1200 machines from the queue are scanned.
You could disable Active Scanning, restart the service and then re-enable Active Scanning. This will prevent scanning from taking place upon service restart.
