Merlin2 became unresponsive to fileshare access today at 5:30 PM. The console was still responding, and we were able to log on. Access to the disk arrays appeared to be impaired – we were unable to list the disks or view their contents. No pertinent events were logged in the Event Log. The system was rebooted, and was back to normal.
We have made an adjustment to the antivirus software (changed vendors), and will keep monitoring.
