I have a sbs2011 server running exchange 2010. It seems as though a lot of the services are not starting up for exchange. The DNS seems to be fine return address of the IPV6 loopback when I ping the server. The IIS site bindings seem to be fine. The exchange management console does not connect properly and the shell does not connect properly as well. Gives error for WinRM client. THrough the logs it states MSExchange ADAccess is the source and that Topology discovery failed error 0x80040a02. THis is causing a large amount of other issues but looks like it is the main source of the problem I am having. I can not even telnet to port 25 on the exchange server. I am not quite sure how exchange got to this point.

When I run a DCdiag the first test that I can see fails is a Netlogon ones. Then it goes through a list of exchange issues. The services in most cases can not start.

Is the Netlogon service started ?
Can you access EMC toolbox ? If yes please run EXBPA and try to fix issues reported

I am not sure why, but the ipv6 got disabled on the domain controls main network interface and services refused to start. Once it was turned on and restarted everything came back up correctly.

Ipv6 should be started on a DC as it is required for communication ... not sure if someone else has rights to the DC and part of some troubleshooting they disabled it
