Ever wondered what would happen if Exchange services are suddenly stopped or rebooted? It could possibly corrupt mailbox stores. Sounds super scary, right? Well, read ahead for a situation that you could face in your wonder days as a SysAdmin.
Consider a Scenario
You are the overworked system admin and the lone ranger. Your Exchange server's CPU is running at 100% for a long time, and you’re getting alerts from your monitoring software. ALERT! ALERT!
After some initial troubleshooting, you decide to restart the Exchange services. The restart process fails, and the CPU continues to run at 100%. Ugh.
The Reboot Disaster
As the status remains the same, you decide to reboot, hoping this will resolve the issue. After 15 minutes, the server finally reboots and as it restarts, some of the mailbox stores do not mount.
The Bad News
The reboot corrupts several mailbox stores, and you discover that a shutdown or restart of the operating system does not necessarily wait for all services to stop. The Information Store service apparently did not stop completely and after a timed delay, Windows shut itself down. You know that the corruption happened because the Information Store was actively being written to when the service stopped.
When It’s Safe to Stop Exchange Services
When you perform maintenance on your Exchange servers, it’s always best to dismount all of the mailbox stores first. This will assure that all "in flight" transactions are completed before the service is stopped.
For example, to stop Exchange Server 2003 services, you must stop System Attendant, IIS Admin service, ExIFS, and SRS (if this service is running), and all dependent services first.
Service Control Manager: Remotely Start & Stop Services
SolarWinds Server & Application Monitor’s new feature, Service Control Manager, allows admins to see all services available on the host, their current state, start-up settings, as well as the services description from within. Stopping, starting, and restarting services instantly is a simple point-and-click affair, all from your Exchange server monitoring tool!
The new Service Control Mangaer feature in SAM 5.5
The very same interface also provides a quick method for monitoring new or problematic services – it’s as easy as clicking a button! The service remediation for any Windows service currently monitored by SAM subtly changes and reduces mean time to resolution when application issues occur by ensuring what you need is readily at hand. So, keep a tab on all those critical Exchange services and control them at the click of a mouse.
