Remove Network Bridge
I have a Windows Server 2012 R2 with 4 on board NICs, someone prior to me set up the server with what appears to be a network bridge between 2 of the 4 NICs. The network property page for each of the NICs in question report back that they are part of a bridge. I do not see the usual Bridge icon in the Network and Sharing control panel. I do not see one listed in device manager either. From what I have been able to deduce, the consensus is to uninstall the NICs via device manager, reboot and allow the system to re-install them. As this server is running among other things, SQL server, and it is in an active production environment, I was hoping not to have to go that route. So any chance there might be a silver bullet that I can use to regain control over these 2 errant network interfaces?
Does the server have Hyper-V installed on it? If so, the bridged NICs are bridged to the virtual switch in Hyper-V. If that is the case, they won't appear as a bridged NIC, but there will be a "virtual" NIC in the adapter list.

I do not see where Hyper V has been configured on this server, its twin is running Hyper V and I see on that server the virtual switch in the network control panel. I have attached a few screen snips of what I see.

Select one NIC, hold CTRL and select the other, right click on one of them, and it should give you the option to remove the bridging.

Had tried that too.....

Do you have any third party NIC teaming software installed?
ASKER
The Broadcom BASCs suite is installed but not configured and the services are set to not start.
When you right click the NICs and select properties, does it show a sharing tab and the list of protocols on the NIC or just the name of the NIC with a configure button?
ASKER
All that appears in the "Configure" button, no normal tabs to set the protocols, IP address, etc.
