You can use the exrca.com tool to perform external testing to try and identify the cause of the problem.

What is the “external lan” you’re referring to?

I set up exchange 2016 to look at external dns Servers as our organization does not allow external resolution. However, it seems to have caused an issue with the exchange services not starting up properly.

When doing nslookup on any other server or computer for mail.xxxxx.com they resolve to the internal it address of our exchange server. But doing this on the exchange server it resolves to the external IP address. When I disable the external lan and restart exchange all services apart from a couple start up fine.

How can I resolve this issue
