Hello,
What version of SEPM are you carrying??
What machine (OS) are you installing the SEPM on ?
I agree with pete and w-d for the scm-server-0.log and catalina.out from the SEPM server machine, to get to root of the issue on what is causing this issue to occur.
However, by the time you upload the logs, you can check the following few things.
1) What error does the Application Logs show in the Event Viewer?
2) In the Services.msc, what Symantec service is stopped, is that Symantec Embedded Database Service OR Symantec Endpoint Protection Manager??
3) Are you able to Login if you try to start any of the above services manually?
4) Did you restart the machine and check logging in the SEPM?
Hope that helps!!
