System.Management.ManagementException 'generic failure' during remote WMI query

[Malcolm McCaffery]

Hi There I'm using a C# Visual Studio 2008 / .NET 3.5 / Windows Vista SP1 to
write a utility that queries windows event log remotely.

When querying a certain remote PC it works fine returning a couple of
hundred events then suddenly an exception on this line.

foreach (ManagementObject oReturn in oReturnCollection) (see below for
context)

It appears to be the same event log entry being read that causes this,
because I am always getting the same event log entry before the exception.

Is there anything I can do to detect the cause of this exception, or trap it
(and continue the foreach loop?)

The exception detail is

System.Management.ManagementException was unhandled
Message="Generic failure "
Source="System.Management"
