Handling unrecoverable monitoring errors.

When Lights-Out detects an unrecoverable monitoring error, a message is displayed in the status page tab and the faulting monitor is marked in red. 

This indicates most often internal server problems like corrupt event logs or corrupt performance counters.

Monitoring errors (created by corrupt performance counters)

No monitoring errors

• First reboot your server. Watch if the problem reappears.
• When the problem reappears try to repair the performance counters (see below) or run Lights-Out Problem Analyzer LoPa.

Log into your server. Open a command prompt (cmd.exe), on Small Business Server 2011 Essentials run cmd.exe with administrative rights. 

Then execute the command:

cd c:\windows\system32
lodctr /R:PerfStringBackup.ini

This command restores your performance counters from an existing backup. Reboot your server. Should the problem reappear, recreate the performance counters and enter:

cd c:\windows\system32
lodctr /R
cd c:\windows\sysWOW64
lodctr /R

Resyncing the counters with Windows Management Instrumentation (WMI):

WINMGMT.EXE /RESYNCPERF

and finally reboot your server. 

Enable disabled performance counters 

Another problem may result from disabled performance counters. To enable these counters download Microsoft Resource Kit Tool Exctrlst.exe. 

Install and run the utility with administrative rights: 

C:\Program Files (x86)\Resource Kit on x64 

C:\Program Files\Resource Kit on x86 

Verify that the counters are enabled. More information is found here:
