AD server is not available - Exchange 2013 ECP
Hi
I just installed Exchange 2013 on a 2012 R2 member server part of a domain with a 2012 R2 DC. The DC has AD DS installed (obviously).
The install appeared to complete correctly however when I go to http://servername/ecp, I get the following message. Also trying to open EMT gives a snap-in error.
Any advice? I used this version of Exchange 2013 - https://www.microsoft.com/en-us/download/details.aspx?id=47679

All services are started and there isn't anything blocking, disabled the firewall to test and it still fails.
Based on the error message you have posted it is clear that "something" is blocking communication. Can you ping via IP/DNS Name? If you are on your DC can you ping the Exchange server by IP/Name? Have you checked the logs on the Exchange server to see if there is any other events which would point to why the communication is being blocked?
Will.

I can ping the opposite server via IP & DNS from both servers.
Where do I find the logs?

This solution is only available to members.
To access this solution, you must be a member of Experts Exchange.
It seems that the AD and Exchange communication is not working properly.. Kindly first reboot the AD servers and let is come up. Once the AD is up then reboot Exchange server and wait untill the services are up on exchange, verify all the services are running specialy MS Exchnage AD topolgy service.

No other solution resolved the problem and as stated in my answer, it was because the Exchange Server's IP had reverted back to DHCP.
There isn't anything blocking traffic between the Exchange server and the DC is there? (firewalls, load balancers, etc.)
