System uptime no longer updates on windows

Symptoms: 

System uptime no longer updates on windows.

Cause: 

Some third party programs can corrupt the registry settings for performance counters.

The issue has been seen with "Symantec Embedded Database" which adds a sem5 entry in "Performance Counter" section of the agent configuration.

Resolution: 

Run the lodctr program from Microsoft. They describe it like this

Registers new Performance counter names and Explain text for a
service or device driver, and saves and restores counter settings
and Explain text.

"lodctr /r " will restore as mush as possible.

Before you can see a change in the SysOrb web interface the agent must be rescanned.
