Oui, j'ai besoin d'une solution
Updated SEP to 12.1.6.1a build to allow install on Windows 10 Enterprise LTSB evaluation. After it was installed, the client never appeared in SEPM. In looking at the client, it looks like the firewall exceptions for Symantec Antivirus weren't created. SMC and SNAC were created. I've tried both the full and reduced size installs. I can manually add the RTVScan entries, but shouldn't those entries be added by the install, like it did for SMC/SNAC? Is this why it's not showing up in SEPM?
