I'm not good at English.
I may use wrong English, so please forgive me then.
I upgraded an existing SEPM server from 14.2 to 14.3 Ru5.
After the upgrade, it is no longer possible to remotely map the C drive (default share) of a Windows computer in the corporate network as a network drive.
Disabling the SEP client allows mounting.
Before the version upgrade, I was able to mount the C drive without any problems.
I checked the SEPM firewall settings.
"Allow Local File Sharing to private IP addresses" contains the appropriate IP addresses.
It doesn't matter which group Firewall is applied to.
Do you know the reason?
