Hello,
I have found a resolution to this issue with the help of telephone support.
It was found that the CRF.log file in "C:\Documents and Settings\All Users\Application Data\Symantec\CRF\" was filling up with the following error message:
----------
05/18/2007 12:01:48 [3]: Initializing reporting engine.
05/18/2007 12:01:48 [3]: Could not load file or assembly 'System.EnterpriseServices, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a' or one of its dependencies. The system cannot find the file specified.
----------
The problem was resolved by uninstalling ".NET 3.0", ".NET 2.0", rebooting, re-installing ".NET 2.0".
Just removing ".NET 3.0" did not fix the problem, this really did require a reinstall of ".NET 2.0".
For the sake of completeness I also reinstalled ".NET 3.0" to see if the problem came back, which it did not.
Hopefully this will help someone else who runs into this same problem.
Regards,
Iain Watson
