Windows Core

We just installed Windows 2016 CORE. As recommened you typically should install all available Windows Updates before you move forward and install other software.

When we started to install Commvault File Agent and Virtual Server Agent setup failed with errors in eventlog and never completed. If you search Application event log you will find two errors logged:

I just installed a Web Console on Windows 2012 R2 Core server and learned how insecure this system is out of the box. You may have worked through the Post-Installation Configurations for Web Server and Web Console. This ends with an highly insecure web server configuration. The SSL encryption is sooo weak that I tend to say you can also leave SSL switched off. You can check your server with SSL Server Test. Commvault default with Java 7 will end with the most worse test result of F.

Java 7.0.17 / Tomcat (Commvault default)
