One of our Child Exchange Server disappeared from the server list of our Exchange System Manager

Hi Experts,

Please help, all our users in one of our remote site has no email because their exchange server cannot be seen anymore in our Exchange System Manager Server list. Our Domain Setup is Parent - Child . We are using Windows Server 2003 and Exchange 2003. Each Site has a exchange server. As far as I know we did not perform any updates and their exchange was working fine yesterday. We can still log on to the Exchange server using our domain credential and the server is still listed in our Active Directory Users and Computers list.

I will send later the log files.

My Last resort is to Un-Join and Re-join our exchange server from our domain.

If you do that, DO NOT REBOOT in between.  Unjoin and rejoin, THEN reboot.
Active Protection takes the fight to cryptojacking

While there were several headline-grabbing ransomware attacks during in 2017, another big threat started appearing at the same time that didn’t get the same coverage – illicit cryptomining.

Have you checked AD to see if the server shows up?  In adsiedit, go to
<your domain or child domain>
Microsoft Exchange
<your Org>
Administrative Groups
<Your admin Group>

Also, take a look at the dependencies tab under the IS service and determine whether it is the IS itself, or a dependency that is failing to start.

Hi Enphyniti,

Yes the Exchange server appeared on the parent and child AD servers, which made our troubleshooting much harder. This incident is like someone accidentally or intentionally delete the server name from the Server list of Exchange System Manager.

Anyway thanks for your comment and suggestion. We just re-installed again the Exchange in our child off-site domain to restore their email asap. On going investigation on our part on why it happened.

Hi Experts,

We decided to re-installing again their exchange server. They need their email badly.
