  • The ESET Security Management Center Web Console (ESMC Web Console) is inaccessible after ESMC 7.x Server was installed using the All-in-one installer.
  • The era.war file located at %ProgramFiles%\Apache Software Foundation\Tomcat_folder\webapps was not extracted into the era directory (Replace Tomcat_folder with the actual folder name in your system).


This issue occurs on Windows Server installations and is caused when the Apache Tomcat service is being logged onto as a network Service. 


  1. Click Start → Run, type services.msc and press ENTER.

  2. Right-click the Apache Tomcat service, and select Stop from the drop-down menu.
