MS released kb4099950 to address the NIC issue that was presented in March rolloup/security updates (KB4088875 and KB4088878). Unfortunately it has to be installed prior to KB4088875 and KB4088878 to help the issue.

I don't see it as of PMImport 7.3.71. I put a ticket in with support asking or ETA and also if the patch intelligence will be updated so that the march rollup and security only update (KB4088875 and KB4088878) will require this as required before installing so our clients don't lose NIC settings. Will report back as I have more info.
