LogJam, RC4 and Forward Secrecy

LogJam, RC4 and Forward Secrecy

When I run a security test on my ADSelfService Plus website using https://www.ssllabs.com/ssltest, I get the following errors:

This server supports insecure Diffie-Hellman (DH) key exchange parameters (Logjam). Grade set to F.
This server uses RC4 with modern protocols. Grade capped to C.
The server does not support Forward Secrecy with the reference browsers.

I can always correct these if I'm running IIS or Apache.  However, I can't find the SSL configuration pages anywhere in the ManageEngine install directory.

How should I secure my server?

Thanks!
