Hello,
Where are you receiving error code returned: 0x80070102?
Is that on the client machine or on SEPM server?
Did you try running the Management Server configuration Wizard?
Please check the Symantec Embedded Database Services and Symantec Endpoint Protection Manager services are running.
If not, please try starting the service and check if you are able to login.
In case not, then please upload us the catalina.out and scm-server-0.log from the server machine.
In case the error code returned: 0x80070102 is from the SEP client machine, in that case check the article below:
SMC service will not start. Error 0x80070102
