Your replies are being very helpful!
I researched how to update the registry to disable SSL 3.
In the registry I see the key had been removed - the path to 'Protocols' had been left open by my tech support who just changed this about a week ago.
I'm reading that the key should have been left in but changed to 'disabled', so that's one concern.
I'm also reading how to fix the Cipher Suite issues shown in the ssllabs.com report.
I will research a bit more before making and registry changes, but it makes sense these need to be addressed.
Thank you again!
