This article contains information about the 'Unknown Error' network status code.
The 'Unknown Error' network status code indicates the audit process encountered an error but was unable to return any further information about the error.
It is possible that the audit agent (EntAudit.exe, ENT NetCenter or ENT Monitor) encountered a problem when trying to establish a connection to the WMI service. If you get this error message systematically each time you try to audit a particular machine then you could probably resolve this problem in the same way that you would resolve the RPC Server Unavailable error.
Another possibility is a corrupted WMI repository. For further information about correcting problems relating to a corrupted WMI repository, please refer to our knowledge base article http://www.microforge.net/kb/102.
