Recently Microsoft released July security patches for Windows OS. Now some of those patches are "buggy". After applying them, we started seeing lots of TCP port conflict issues. In our case, Apache httpd as well as Tomcats were affected. Symptoms matches what you mentioned in the mail. netstat will show ports are free but TC will not be able to bind to it. So, we decided to uninstall those patches and after that everything came back to normal. Here is some details: https://www.computerworld.com/article/3290465/microsoft-windows/stung-by-a-festering-pile-of-bugs-on-patch-tuesday-ms-releases-27-more-patches.html To fix this issues, MS has released another set of patches. :) Can you please ask the affected users to uninstall July security patches and try again? Thanks!
