How can I get my Windows 10 laptop recognized on network quickly by its UNC address

[zmatch]

I use a large domain network at work, with an always-on workstation and a laptop that goes home with me. When I am away with the laptop, on a home network for example, and return to work put my laptop in its dock in the morning, I cannot access from the workstation over Windows in File Explorer using its UNC name \\LAPTOPNAME\C$. If I wait a long time, maybe 20 minutes, I can eventually connect to it. Until then, if I ping LAPTOPNAME, it gives me a stale IP address.

I can immediately connect from the workstation to the laptop using its IP address, 10.127.149.111, for example, if I do an IPCONFIG on the laptop to find its IP address and manually type it into the workstation File Explorer, like \\10.128.149.111\C$. That is awkward, of course, since the "recent files" list in applications will reference an old network address in the future, instead of \\LAPTOPNAME\C$, for example.

Is there a way to immediately force the workstation to get the up-to-date IP address, not the old one? Or perhaps force the domain controller (?) to return the correct IP for the laptop? It seems like the workstation DNS cache is not to blame, since the FLUSHDNS doesn't seem to fix it.

I have tried many things, including some long-shots, on both machines.

IPCONFIG /RELEASE
IPCONFIG /RENEW
IPCONFIG /FLUSHDNS
GPUPDATE​

Thanks.
