In the ESM > Server Properties > Directory Access > Configured for "All Domain Controllers" and only two of my 4 DC/GCs show up (one is in second site, three in same). Automatically detect servers is checked. Native 2003 domain w/ one Svr2008 DC/GC.Is there a way to force discovery of at least the three in the same site? Thanks!

Please the event log entry from the 2080 event in the app log of the server:http://support.microsoft.com/kb/316300Event ID 2080 from MSExchangeDSAccess

Process WMIPRVSE.EXE -EMBEDDING (PID=3596). DSAccess has discovered the following servers with the following characteristics: (Server name | Roles | Reachability | Synchronized | GC capable | PDC | SACL right | Critical Data | Netlogon | OS Version) In-site:dc1.domainname.org CDG 7 7 1 1 1 1 7 1dc2.domainname.org CDG 7 7 1 0 1 1 7 1dc3.domainname.org CDG 7 7 1 0 1 1 7 1Out-of-site:dc4.domainname.org CDG 7 7 1 0 1 1 7 1*I see they are all discovered here, both sites, but not listed in the GUI. Is this expected?

Is this server installed on a DC? I cant quite tell from your initial post. BTW, The event 2080 you posted looks normal and expected.

Please veryfy thisA. Open theDefault Domain Controllers Security Settingssnap-in on the domain controller specified in the event description. In the console tree, underSecurity Settings, expandLocal Policies, and then clickUser Rights Assignments. In the results pane, double-clickManage auditing and security log. Verify that both theExchange Serversgroup and theExchange Enterprise Serversgroup are listed.==============================================Exchange server is still a member of the Exchange Domain Servers group. Also, make sure that the Exchange Domain Servers group is a member of Exchange Enterprise Servers group.================================================Check this post http://social.technet.microsoft.com/Forums/en-US/exchangesvrgeneral/thread/4cfab637-4d82-4c03-9362-5fa11777c70d/ Raj
