Microsoft SSL Diagnostics is as Secure Socket Layer (SSL) troubleshooting tool for Internet Information Services (IIS). A common problem for administrators of IIS servers is configuring and troubleshooting SSL enabled websites. To assist in administrators efforts, Microsoft has designed a tool - SSL Diagnostics - to aid in quickly identifying configuration problems in the IIS metabase, certificates, or certificate stores.

This tool allows users to review configuration information in a easy to read view mode or to run the tool silently with only the creation of a log file. During use, administrators can simulate the SSL handshake to find errors. They can also quickly "hot swap" certificates for testing purposes.

These packages come in two forms: Express and Full. The express will only give the pertinent tools for administrators to use SSL Diagnostics while full install installs the same files with the appropriate documentation. Included in the full install is a SSL Frequently Asked Questions that can assist in the learning of SSL for administrators.
