Hi all! i have 9 domain controllers over two sites and one of the domain controllers is running exchange server 2007. when i transfered the PDC and RID roles to a newly installed server, and open 'AD domain and trusts' and right click on properties it shows PDC emulator can't be found. Kindly help me with this :-) here's the output of dcdiag: ************************************************** Domain Controller Diagnosis Performing initial setup: * Verifying that the local machine ICCSERVERAD, is a DC. * Connecting to directory service on server ICCSERVERAD. * Collecting site info. * Identifying all servers. * Identifying all NC cross-refs. * Found 9 DC(s).

I see two PDC role owners in your output. Do you get the same results if you use dcdiag /v? This shows all of the FSMO role owners in one section. Also, the PDC emulator should be specified by the fSMORoleOwner attribute of the domain object. You can use ADSI Edit to browse the attributes of the domain object (dc=domain,dc=local) and view the fSMORoleOwner attribute. There can be only one value, and I would say that value reveals the DC with the PDC Emulator role. I cannot explain how your output indicates two PDC role owners. Richard MuellerMVP ADSI

Hello, Thank you for your post here. 1. I'd like to know whether you experience the same issue on all DCs in the domain in two sites? Or do it happens on the DCs in separate sites? 2. Is there any customized replication period between two sites? If yes what happens if you force the replication between two sites? 3. Please help to collect the MPS report on 2 DCs in different site for further investigation and upload the CAB files to Skydirve (you may send the URL to me at v-mileli@microsoft.com for troubleshooting).

Hi There,Apart from the suggestions from the engineers above, i would suggest not to install the exchange server on DC . please find a supportive document http://technet.microsoft.com/en-us/library/aa997407(EXCHG.80).aspx
