SSL Diagnostics tool for Windows Server 2003 is no longer available for download on TechNet. I had to ping my peers to who had a copy of the tool which they had downloaded earlier.
Main stream support Windows Server 2003 ended in 2010, while extended support will end next year in 2015. Click here for more details
For server admins and support folks who still work on IIS 6 realise that SSLDiag was a great tool. I’m sharing it here, in case anyone needs to download it:
