Diagnosis-DPS Logs

Hello friends!

After installing SP1 on my Vista Ultimate system
I had 2 entries with level Error in the Diagnosis-DPS Log.

Clicking on Event Log Online Help I can read in the online page:
"If a Windows system error code containing four or five digits is included,
you can find the explanation of the error code on the Web ..."

But I could not detect such error code.

I read in Microsoft Technet that no manual invention is necessary
but I am interesting in which environment the errors occur.

Perhaps there is a list to read about it.

Thank you
Erhard.

PS. the error entries in my system:
