To happen on one PC, it is okay. But to have it on 50 PCs, seems there's a conflict with other application/service. I would suggest to debug SMC.EXE and send it to Symantec Support.

Dear all,

I solved the issue, as bellow:

Remove the Symantec Client using the installation package that I did download from Symantec Website.


Restart the Desktop.

Reinstall the SEP client using the same package that I did download from Symantec Website, and install unmanaged type (single instalation).


After finish the instalation, stop the smc services.

smc -stop

Export the Sylink from SEP Manager, and import to SEP Client.

Start the Services smc or restart the computer.

smc -start

Check in the SEP Client in troubleshooting if the General Information show the SEP manager server.

Best Regards

Grande Bart.
