this is likely this issue as I did the same thing and it seems to have resolved the issue
I connected to at least 4 MS techs about this issue and none of them had the slightest idea about how to troubleshoot this problem.
it goes back to LAN support as far back as win 95 as far as networking on Windows and the current techs have no clue.
One tech told me to forget it because it was merely a "legacy" issue
