I would have liked to have seen the actual ipconfig /all output
ipconfig /all >ipconfig.txt but from the looks of it, the problem is caused
by the two network adapters on the same server connected to the same network
on the same subnet facing each other with NetBIOS enabled on both. When you
do this, the two adapters broadcast the NetBIOS name to the same network and
both get ignored.

You need to disable one NIC, or use Teaming software for the NICs that will
make them act like one connection with one IP address.
