I can already say just after glancing at the article that I DO NOT have reverse lookup zones for at least one office. That might be my problem. Let me look. Will reply tomorrow. In which event log will I find these errors? The System log?
Issue with DNS records not updating
I am running Server 2016/2019 DC's. DCs are located in 4 different offices connected by vpn connections. All servers are in the same domain.
DNS is AD integrated. All DCs run dhcp and dns.
I have two DC's in the main office and one DC in remote_office1, remote_office2, and remote_office3.
Issue: Earlier this week I went to remote_office3 and did some work with my laptop. The next day I returned to the main office. I needed to scan a document to my laptop and after it failed I troubleshot and found out the reason was because my laptop was still in DNS with a pointer record from the subnet in remote_office3. I have seen this happen before and I am not completely sure there is anything wrong. My dhcp servers, on the DNS tab, have the options set for "always dynamically update dns records, and discard a and ptr records when the lease is deleted".
This problem does not happen very often as people work out of the same office most times. What do I need to do to make sure I have everything setup properly and how can I make DNS records update quicker or what can I do to make this work more smoothly for when someone goes from office to office? Thanks for the help
