We are using Symantec Endpoint Protection Version 11.0.2010.25.
I just read through the thread you're referring to. Doesn't appear to me that any of the solutions there are 100% positive solutions. Appear to work for some and not others. I'd rather not monkey with registry changes, etc for a solution that may not work.
Are we missing a critical update or something? How do I go about getting the Maintenance Release?
