Our Exchange 2003 server every day at the same time freezes with 100% CPU. The server freezes for about 30 minutes. The process that is maxing it out is svchost which has many services. We started restarting each service and once we restarted the server service that had dependent Exchange services (MS Exchange MTA Stacks, MS Exchange Information Store and MS Exchange System Attendant) the CPU usage went down. Any Idea whey this is occurring?
This server is a virtual server in a VMware environment.
