Dear Techies, I have an environment which contains Domain Controller (win 2k3), additional DC (win 2k3) for fault tolerance and clustered exchange servers (exchange 2003). Actually our primary domain controller is in very old hard ware so we planned to move the PDC to new hard ware, we planned to transfer the fsmo roles to additional domain controller and demote the primary domain controller, after demoting the old domain controller we will install win 2k3 in new hard ware and promote it as an additional domain controller to the existing one. We planned like this, so far I am clear from active directory side but from exchange side what changes we have do before demoting the old domain controller. Can anybody explain the procedure what we have to change in exchange servers. Thanks in advance for your valuable support. Thanks & Regards Phani Kumar .B

Hi Phani, You dont have to worry about it. Exchange will automatically detect next available DC/GC if it is set to Automatically detect servers in Directory Access option. Refer below article to understand more about Directory Service Access. http://www.msexchange.org/tutorials/Closer-Look-Directory-Service-Access-DSAccess-Part1.html

Hi Amit,Thanks for your reply, when I tried to access directory access option in my exchange server I got the following error can you please give the solution for this problem.I am getting this error only when I access directory service option and the remaining all are working fine.Access Denied Facility: win32 ID no: 80070005 Exchange System Manager Thanks in advance for your valuable supportThanks & RegardsPhani Kumar .B

Hi Phani, Are checking with an account with Exchange full admin rights? Looks like, it is having some permission problem. Additionally if you are checking in Exchange System Manager which is installed on workstation then check on server directly. You can also look for event log 2080 to verify the DC/GC detected by exchange server. Event ID 2080 from MSExchangeDSAccess http://support.microsoft.com/kb/316300

Hi Amit, Thanks for your responce, I am checking with an administrator account (which is a member of the following groups Administrators, Domain users, Enterprise Admins, GPO Creator Owner and Schema Admins groups ), I think that this account has sufficient permissions, I am checking it in exchange server itself not in a workstation. I am getting this error only when I access directory service tab in the properties of my exchange server and the remaining all things are working fine.Error is:-Access Denied Facility: win32 ID no: 80070005 Exchange System Manager Thanks in advance for your valuable support.

Hi Phani, As we suggested in another thread, please run EXbpa first, and let us know the result. Meanwhile, please try dcdiag/netdiag to see if there is some AD issue. After a research, I think it could be a AD problem now. Meanwhile, please try the suggestions in the following thread: http://forums.microsoft.com/TechNet/ShowPost.aspx?PostID=4119436&SiteID=17 If there is any error in event log, please paste it here for our discussion. Is there any error regarding Kerberos? Thank you, Elvis
