I am noticing that when my exchange 2010 servers are discovering domain controllers all of them are found except for DC's in one state.  All of my california DC's are not being found.  We have 3 AD sites in CA (LAX, SFO, and IRV) and none of those DC's show up in my event 2080 as being out of site DC's.  Its not an error or even a warning, just those DC's do not show up in the list.  Any ideas on what to troubleshoot here?

This article has a good description of how Exchange DA Discovery works and a few steps to explain why some DCs don't show up under the Event 2080

The issue is most likely with your AD Site Links.  Exchange will only discover the local and adjacent DCs (if they have the same link cost.)  If you have multiple adjacent sites with the same link cost then you should see the local DCs in the In-site list and all of the other DCs in the Out-of-site list.  If each AD site link has a different cost, then Exchange will only discover the DCs in the adjacent site with the lowest Link Cost.

Thanks!!  That would be it.  We do have two site links and all the CA site are in a separate link with a higher cost.  Which is why Exchange is not discovering them
