Doing some grave digging here... Anyways, last year I got the private fix 200.5.10.0.293 . I'm planning to upgrade to 200.6.10.1.308 (GA Refresh) . Reading the release notes, 200.5.10.0.291 is the latest version that can be upgraded to 200.6.10.1.30...
.291 is out, but does not fix the problem described in this topic (or my problem). I just got .293 privately and it fixes the problem with RRAS encryption settings.
