We still need good tools to help troubleshoot SSL issues on IIS 7 and IIS 7.5. Then we have two choices,

Use The Official SSL Diagnostics Tool for IIS 6

1. Turn on IIS 6 Compatibilities features on IIS 7.*.

2. Install SSL Diagnostics 1.1 for IIS 6.

3. Run SSL Diagnostics tool as administrator.

Use This Non-official SSL Diagnostics Tool for IIS 7.*

My colleague Vijayshinva created this small tool for IIS 7.* and it works fine without IIS 6 compatibilities,
