Issue/Introduction

Getting error "Unexpected Server error" or "Failed to connect to Server" while logging in to the Symantec Endpoint Protection Manager (SEPM).

Cause

conf.properties file is blank/missing parameters

Resolution

Check whether conf.properties is empty.
Default Path: C:\Program Files (x86)\Symantec\Symantec Endpoint Protection Manager\tomcat\etc\

1. Copy the conf.properties file from a working SEPM or from a backup file
NOTE: If its a "hybrid / cloud enrolled" SEPM, be sure to use a "hybrid" specific conf.properties version for comparison and rebuilding purposes.  A non-hybrid SEPM version of conf.properties is "missing" parameters needed in the hybrid version.   

2. Follow the below steps to update the conf.properties file 

a) Stop the SEPM and SEPM Webserver services

b) Add/Modify the below values as per your SEPM (NOTE: Hybrid SEPM "conf.properties" version has additional parameters that are "required" that don't exist in a non-hybrid SEPM set up) 

scm.db.datasource=jdbc/metadatabase
scm.agent.root=C\:\\Program Files (x86)\\Symantec\\Symantec Endpoint Protection Manager\\data  (modify the drive as installed)
scm.liveupdateclient.path=C\:\\Program Files (x86)\\Symantec\\LiveUpdate
scm.server.version=<your SEPM version, in the format 14.2.1031.0100>
scm.agent.kcs= (This value can be found in Server Private Key Backup - recovery file - Setting.properties file. Encryption password is the scm.agent.kcs value)
scm.server.id=  (This value can be found in Server Private Key Backup - recovery file - Setting.properties file.
scm.db.client.bin= C\:\\Program Files\\Microsoft SQL Server\\Client SDK\\ODBC\\130\\Tools\\Binn  (This value is the path to your bcp.exe on the SEPM)
scm.server.name= (This is your SEPM Server hostname)
scm.site.name=   (This is your SEPM Server hostname)

c) Start the SEPM and SEPM Webserver services

d) Run the Management Server Configuration Wizard, then attempt a login to the manager.
