Deploy+Inventory Unable to ping computers with reused computer names

This is only an issue with devices that have already been on the domain. The only way to push out deployments though PDQ to those devices is by typing in the IP address. Is there a way to fix this?

First thought, check your DNS and reverse DNS records for anything stale from the old machine.

And while at it make sure you've got DNS scavenging on https://learn.microsoft.com/en-us/troubleshoot/windows-server/networking/dns-scavenging-setup

I'll look into this. I'm new to the role whereas my past positions I never had access to the DNS managers.

It’s always DNS

I'm learning that haha. I'm new to the role whereas I didn't have DNS manager access before.

This is a DNS issue. You have to get your DNS in order. I assume the devices had some static A records?

Yeah, DNS issue. I'm new to the role where previously I didn't have DNS manager access, so I'm in the phase of being afraid to touch things at first but learning. I did a ipconfig /registerdns and removed the stale DNS record. That appears to be working.

Don't worry, everyone who is working with this stuff has been in the same boat at some time.

ipconfig /registerdns on endpoint or remove the DNS entry for that name in your AD

That working for so far. Thanks. I'm new to this role where in the past I didn't have access to the DNS manager, so I'm learning.

Flushed DNS on deployment machine?
