From the Disk Drive Performance Counter Information page of the Troubleshooting Assistant: SMTP drive: Maximum '\LogicalDisk(C:)\Avg. Disk sec/Write' should be less than 50 (0.05 ms). The measured maximum value is (NaN ms). Several of the data points are "NaN ms", what does that mean?
Additionally: under Other issues, the Troubleshooting Assistant failed to analyze the ETL file - Time Range: 01/01/1601 00:00:00 - 01/01/1601 00:00:00 That date range (which the Troubleshooting Assistant selected) isn't very helpful.
