We're monitoring our Windows SOFS and Hyper-V clusters nodes with PRTG. When trying to add Windows Network Card sensors to the devices, only a subset of the network cards are appearing. For example, for one of our SOFS servers, only 1 NIC out of 5 is showing, and on the other SOFS server 2 NICs are showing out of 5. The hardware and OS is identical between the two. Windows Server 2012 R2. Any ideas?
