The model of the server is a Dell PowerEdge T410 and the NIC being used is a Broadcom BCM5716c NetXtreme II GigE (NDIS VBD Client)

On the Server:

I configured the NIC on the server with Smart Load Balancing and Failover and assigned that NIC a static IP. I set it up on vlan 1, untagged.

On the Switch:

I configured LAG via the LAG membership page. I did not make any other configurations because all ports are on vlan 1 and by default the lag is untagged. I could not find that feature to set the LAG to access mode.

Problem:

I can access the internet and shared drives from the server. I cannot not RDP into it from another machine or access a machine from the server. I cannot even ping the server from my workstation.

I have the switch connected to other unmanaged switches on my network. I don't know if that might make a difference.

I can rdp into the workstation on the 2848 switch from another switch, but i cannot rdp into the server.

Yes I do have a DHCP Server on the network. From the server I am not able to ping the 2848. I am not able to ping any workstation on that same switch. The server and workstation are on the same subnet. There was nothing of note on the Event Viewer of the server regarding networking or rdp connections.

I restarted the server and now I can rdp into it, but i lost internet connection and connection to my shared drives. I have a yellow triangle with a question mark in it on top of the notification sign of the network connectivity icon on the desktop.
