Server shares aren't responding on Windows Server.
Server shares aren't responding on Windows Server.
I need a new perspective to guide me. I regret the low quality of the diagram provided, but it's only for reference. My issue is this: my Windows Server 2012 R2 was initially connected straight to the switch, so all its settings and network SMB shares were configured there. Everything functioned perfectly at first. Now the server isn't working properly—it needs to be near the router, but the PC on the switch can't access any network shares. If I reconnect it to the switch, it works fine again. The switch model is a D-Link DGS-108 (unmanaged). Are there any details I'm missing? Feel free to ask if you have questions.
It appears you're asking about the type of router you have, its connection to a LAN port, and whether it's handling multiple LAN networks or assigning IPs differently from your switch.
It's an Asus RT-AC68U. For the network configuration it isn't isolated, so ideally everything should share the same LAN setup. That's a good point about assigning the same IP address. I'm not sure if anything unusual was detected with the IP already given, but I'll double-check to be sure. The DHCP server has a valid IPP assigned, and it's definitely on a single LAN port. Same domain as expected.
