Dear Techies,I am running win 2003 and exchange 2003 in my environment, Recently I added an additional DC to my Primary Domai9n Controller, but DSAccess is not detecting my additional Domain Controller, as per my knowledge it should automatically update but it is not updated, even I restarted the exchange server but no luck, does it take time to replicate??Can anybody help me in this issue pleaseThanks in Advance.Regards,Phani Kumar .B

Hi Phani, It may take couple of days to fully replicate. Do you get new DC name in event id 2080? If so then what is the reachability value in it as per below KB. If new server is listed in the event log then you need to check the connectivity onport3268 for GC & port 389 for DC. Additionally run DCDiag and NetDiag for any issues. Event ID 2080 from MSExchangeDSAccess http://support.microsoft.com/kb/316300

Hi, Please set the diagnostics logging level for all categories of the MSExchangeDSAccess service to Maximum, Exchange System Manager automatically obtains detailed information about the initialization of DSAccess and places that information in the application event log. Through this, we can confirm whether any valuable information come up. Thanks Allen

Hi Allen,Thanks for your reply,I already set diagnostics logging level for all categories of the MSExchangeDSAccess service to Maximum and waited for 3 days to update but no luck, after that I tried to add domain controllers manually, I added both of my domain controllers but for ADC it is showing as unknown.I found a event 2080 after adding this domains manually, Process MAD.EXE (PID=3168). 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:gc.domain.int CDG 7 7 1 0 1 1 7 1bdc.domain.int CD- 0 0 0 0 0 0 0 0Out-of-site:Now I stuck in this situation can anybody please guide me.Thanks in advance for your valuable support.Regards,Phani Kumar .B

Are you sure your 2nd domain controller has installed and activated correctly? In other words, are you sure it's seen as a valid domain controller by the existing domain controller?

Hi,I am sure that my 2nd Domain controller is installed perfectly and the replication is also going fine, no errors found in the logs, I cannot trace that what is wrong from exchange side. please help me to solve this issue as early as possible.Thanks in advance for your valuable support.Regards,Phani Kumar .B

Hi, Please click Start, input gpedit.msc in the new DC, expand Computer Configuration->Windows Settings->Security Settings -> Local Policies -> User Rights Assignment -> Manage Auditing and Security Log, double click it, what user was listed in that interface. Please let me know. Thanks Allen

Hi Allen,Thanks for your reply,As specified by you I checked the Manage Auditing and Security Log in the new DC, I found only "administrators" in the list, if you need more information please let me know, I have to solve this problem as early as possible.Thanks in advance for your valuable support.Regards,Phani Kumar .B
