This server is vulnerable to MITM attacks because it supports insecure renegotiation. Grade set to F.

Hi Team,

I am using windows server 2003 web in my office but while doing SSL test(https://www.ssllabs.com/) for 

https://webxpres.tdc.dk/ getting F grade. But my client wants to set it to A. How prevent MITM attacks and upgrade the security.

Regards,
