I installed nw65sp6 on my BM3.8sp5 server today, and then re-installed the BM38sp5. When I try to connect to the C2S VPN I get "Failed NMAS Authentication", followed by the above error. I can connect and authenticate Ok if I set the VPN client to backward compatibility, but then I can't connect to anything. This worked fine prior to the sp6 patch. Is there a log file I can look at or anything else that can tell me what the issue might be? Nothing showing up on the IKE screen or anywhere else that I can see.

Thanks for any help or suggestions!
