Dirk, I will certainly try re-enabling TLS 1.1 and/or SSL 3 and see whether that solves it for the time being.
I had disallowed the other protocols after the heartbleed alerts came out. Reference, for example, https://www.digicert.com/heartbleed-bug-vulnerability.htm Thank you very much for the clear answer on this one, at least now I know what I am dealing with. This does strongly imply that IE10 and IE11 do not implement TLS 1.2 either, which is contrary to the implication of the [x] tick they offer under options. (!!)
