Hi,
Thank you for posting in Symantec community.
I would be glad to answer your query.
Try the following steps
1) Try to repair the Symantec Endpoint Protection Small Business Edition through add/remove programs
Not helped then
2) Go the services.msc, try to start Symantec Protection Center and Symantec Embedded Service.
If service didn't start then
3) Attach scm-server-0.log and catalina.out log file. Also check event viewer details.
These logs should be present under (SEPM installed drive)\Symantec\Symantec Protection Center\Tomcat\logs
