For some unknown reasons I am having unexpected restart of ALL DC. At first I thought it was a power failure - but its happening ONLY on the DC. In the error log the only major errors I see are:

DC3 -
DCOM was unable to communicate with the computer exchangeiii.domain.us using any of the configured protocols.DCOM was unable to communicate with the computer exchangeiii.resdevelopment.us using any of the configured protocols.

exchangeiii is the only exchange which I previously upgraded and had to do a clean up in order to remove.

Hi,

I doubt the DCOM error is directly related to the crash, but more information is required. Start here:

I actually recommend starting a case with Microsoft, if all your domain controllers are crashing regularly, that has the potential to turn into a big problem for you. Microsoft cases don't cost much and they will analyse all your server logs and the crash data for you and probably get it fixed much faster.

Cheers,

Kalti - I am on experts to try to trouble shoot myself. Calling Microsoft, buying a new server, replacing the IT department will for sure fix the problem.

Your first point of investigation for any Windows based system is the event viewer.
Look for errors around the time that the servers stopped responding.
You also need to consider the impact of any recent updates to OS or hardware of these servers.

Without any error messages we are unable to help you.
DCOM Error would not have any influence on your DC's shutting down.
