I'm using an MX84 security and SD-WAN connected to a 2960 cisco switch. the Win server 2012 is connected to switch which are all on the same subnet. Workstation cannot authenticate and connect to the domain once i connect the MX84 but work well once i change the router to the old cisco 19xx. I didn't set any VLAN on the MX84 i used the single LAN settings. I will appreciate any suggestion how i can solve this
