Does the dock install a separate network adapter?
The best course of action is probably going to be to get a dock made for that laptop that supports NIC/MAC address passthrough.
Hi Folks, first post here. LMK if there's a better subtopic or thread for me to post this in please.
Basically, the issue is users not being able to RDP in. The reason why seems to be that their USB-C Dock changes IP address for host, breaking DNS and RDP service. And it might happen when the laptop goes to sleep, but we have a GPO that's supposed to prevent them from going to sleep.
I'd appreciate any sort of perspective or ideas you could share. Just something to get my brain working a different way...

Thanks Big Green Man you're reply has many layers. We're considering going with docks made by the same manufacturer of the laptops in question.
I'm confused as to how the IP changing is breaking DNS. What are you using as your DNS server? If it's also your DHCP server, it sounds like the DHCP and DNS services may either be misconfigured or setup to not communicate with one another.

If the record's TTL is short enough, this shouldn't be a problem. If it's not, clients with the old records cached will fail to resolve until their resolver cache is cleared, even if the record is updated on the DNS server.
changes the host address? if the device is dhcp, then it is the server that would change it upon dhcp request if it needs to.
Is the host only using the dock for network (no othr wired nic, no wifi)?
What are the dhcp lease times - that is the likely cause.
I would suggest that Big green Man's suggestion of making sure DNS is updated is the best resolution to this.
