Hi,JWHNL
Welcome to the Microsoft Community.
Based on your description, I understand that you are having problems accessing your local devices over your LAN.
I wish I could handle your problem, however, the issue is out of reach of the response support community. It is more suitable for publishing on Microsoft Learn (English only), you can click on "Ask a question", there are experts who can provide more professional solutions in that place. Here is a link to the forum where you can raise specific scenarios and share your idea to help solve the problem. Sincerely hope that your question will be dealt with appropriately after contact the correct department. Thank you for your understanding!
Wish you solve the trouble soon!
Best Regards,
Huon | Microsoft Community Support Specialist
