exchange 2016 suddenly stopped working
i have installed a fresh installation of exchange 2016 CU5 on a fresh clean system. also a newly constructed domain forest. so no previous domain garbage.
i followed the regular instructions. prepared the schema and did the install. restarted, configured a send connector and everything worked perfectly without an issue.
suddenly and without a clear reason. exchange just stopped receiving any messages. and when i try to send a message it goes immediately to the drafts.
the firewall gets the messages tries to communicate with exchange but nothing happens. when i open the queue viewer there is nothing there at all. the main submission queue disappears and appears.
beteween the time it was working and the time it stopped working nothing at all has changed. the system is still the same.
the case is really urgent so any help will be appriciated

Exchange connectors are tied deeply to the name resolution. You can ensure that the server can resolve its own name correctly (loopback, short netbios name, full fqdn name). Additionally, ensure that your exchange servers are up, that there are enough resources on the system (memory, processor, disk) and the status of your queues (You can check it using Get-Queue, after performing a test, and you can send us the result).

well like i said nothing has changed between the time it was functioning and the time it stopped.
and yes it actually can resolve itself and its name.
if you have an tests i can run im all open to it.

also the system resources are all fine. enough disk space, enough everything its all fresh. there is even no data in the tabases. they also appear to be healthy.
If your emails going to drafts it's mean that Send Connector can't communicate with smart host or if you're using MX record there is a problem with DNS name resolution on Exchange.
Try restart Transport Service and just after do nslookup to some domain you're trying to send email to. Leave info in dos window and wait. If server wil get problem again do nslookup again to same address and compare results.
You can also check your internet connection, Root Hits on DNS and some tracert to domain you're trying to send email to.

well here is the issue its not sending anything to anywhere any more or receiving anything from anywhere anymore. its as if the transport service doesn't exist anymore
NSlookup works fine.
tracert to Hotmail or google mail where it doesn't send or receive anything still looks fine.

Drafts is for sending emails not receiving, so please clarify your issue

when i logon locally to the exchange server i can actually ping the domain controller on the new IP but something is still off i cant logon the domain
Was it necessary? If yes, then you will need to change IPs at many places...
- dns server of your exchange
- applications using your server as an smtp relay.
- bindings of your connectors (onless they were set to use any ip address)
- bindings of your iis websites (onless they were set to use any ip address)
- appliances (if any), delivering messages to exchange.
- etc.
If you need to make it, better wait to resolve the problem at first.

the setup has only two servers. the DC and the Exchange,
so i changed the Ip range on both.
they can communicate and they can ping each other and i can even resolve names.
what i just noticed is that login doesnt respond to the domain name anymore but to the Pre windows 2000 login name.

further i also discovered that i can login when i do this.
domain\administrator (doesnt work) it used to untill i changed the IPS
domain.local\administrator (works) didnt matter before the ip changes.
