After Configuring MSDTC on Computer and SQL Server, with our Network domain area, it's work fine but when i tried to connect on Remote ( Using VPN Forticlient ) i couldn't due to firewall block.
I already checked the configuration :
Configure MSDTC / Add MSDTC to Windows Firewall exceptions list / Add exclusion Port to Firewall.
even the traffic is opened on Firewall
Thanks if can help me
