Server Fault is a question and answer site for professional system and network administrators. It's 100% free, no registration required.

I ran into a problem while installing our Exchange 2010 server where client access authentication does not work unless the server is configured as a domain controller with global catalogue.

I went to production with this because of time constraints but I really need to fix it now. I have no idea where the problem could be or how to identify the problem.

My question(s) is(are):

What could cause this issue? How could I test it and repair it?

I don't really know what information would be relevant to the issue but;

Server OS is Win 2008 R2 and all DCs are the same. Exchange server has CAS, Hub Transport and Mailbox Server roles. External mail is received by another exchange 2010 server running the Edge role in the DMZ. (this works okay and Edge server is not a DC... obviously ;) )

Please let me know what additional information could be added to improve this question. I will add it as soon as I can.

This is a follow-on question from this.

What do you mean by "local"? Do you mean if there is no GC in the same site as the Exchange server? –  MDMarra Mar 19 '13 at 2:36

Good question. I should word that better. I mean local in the sense that the server is a DC with a global catalogue. If I don't have the global catalogue on the server or I change the domain controller exchange uses it stops authentication working. –  Ablue Mar 19 '13 at 2:58

Exchange 2010 servers requires a domain controller with a GC in the same site.

Also, running Exchange on a domain controller is not recommended. And you definitely can't promote an Exchange server to a domain controller.

It sounds like from your description you broken at least two of these rules, if not all three.

Solution offered by ashdrewness


It's not supported to run dcpromo on a server after exchange is installed. It's also not supported to do an in-place upgrade from std to ent with exchange installed. You have to uninstall exchange or perform a disaster recovery install of exchange (setup.com /recoverserver).

From http://technet.microsoft.com/en-us/library/aa996719(v=exchg.141).aspx

Installing Exchange 2010 on Directory Servers

For security and performance reasons, we recommend that you install Exchange 2010 only on member servers and not on Active Directory directory servers. However, you can't run DCPromo on a computer running Exchange 2010. After Exchange 2010 is installed, changing its role from a member server to a directory server, or vice versa, isn't supported.
