Does CSW Client logging work?

[GraemeBrowning]

Following advice, I installed the CSW Clients on ArcGIS for Desktop 10.1 and ArcGIS Explorer Desktop Build 1750.

I have no problem configuring either, and getting access to their respective interfaces, but every search to a Catalog Service that I have been asked to test says "No records found", which is contrary to expectation. 

To debug this, I am trying to turn on CSW logging.

In C:\Program Files (x86)\ArcGIS\Desktop10.1\bin I have edited CswClient.properties to be:

logFolder=C:\ProgramData\ESRI\Geoportal\CSWClients\Logs\CswClient.log
maxLogFileSizeInBytes=500000
debug=on
dataFolder=C:\Program Files (x86)\ESRI\Geoportal\CSWClients\Data

And in C:\Program Files (x86)\Explorer\bin I have edited CswClient.properties to be:

logFolder=C:\ProgramData\ESRI\Geoportal\CSWClients\Logs\CswClient.log
maxLogFileSizeInBytes=500000
debug=on
dataFolder=C:\Program Files (x86)\ESRI\Geoportal\CSWClients\Data

I've then restarted both ArcGIS for Desktop and ArcGIS Explorer Desktop to perform the searches again.

However, C:\ProgramData\ESRI\Geoportal\CSWClients\Logs remains stubbornly empty of any files.  I can create a test folder there so I do have write access.

Does CSW Client logging work for anyone else?  Can anyone spot anything that I may be doing wrong above?
