Noel Pereira 2008-02-06 12:08:01 UTC Permalink Hello Meinolf,Thanks for your king Cooperation. I have promoted Backup Domain controller to PDC by seizing all five roles. Now while working on users and computers ,When i attmept to display members of any security group , i got the following error. " A global catalog cannot be located to retrieve the icons for the member list" Then i configure this new PDC as global catalog server.After that i am not getting any error when working on the "Active Directory users and computers" Kindly advice me, is there any problem configuring 'global catalog server' and 'infrastructure master' on the same Domain Controller ?. what are the impacts will happen ? and please advice me how to solve this issue ?

Meinolf Weber 2008-02-06 13:06:31 UTC Permalink Hello Noel,Just one note before. Since windows 2000 there are no longer the terms PDC/BDC, all Dc's are the same, the differences are in the FSMO roles. Did you run dcdiag and netdiag before starting with the new server on the old machine to see that everything is ok and without errors? Please describe the steps you have taken to promote the new machine. Also post an ipconfig /all from both machines.

Noel Pereira 2008-02-13 12:26:04 UTC Permalink Hello Meinolf,Backup Domain Controller is done and i can open the Active Directory. The Problem now is , What ever the modification i m doing in the Primary Domain controller is not replicating in Backup Domain Controller. So i planned to demote the BDC and Promote Again. When i start Demoting , i could see a error message " A Domain Controller could not be contacted for the domain SevenSeasgroup.co.ae that contained an account for this Computer". Please let me know what is this error ? Why the modification is not replicating? Regards Abdul rahuman.M
Meinolf Weber 2008-02-13 12:54:58 UTC Permalink Hello Noel,Do not demote in the moment. let's try to find your problem. As ia sked BEFORE: Did you run dcdiag and netdiag before starting with the new server on the old machine to see that everything is ok and without errors? Please describe the steps you have taken to promote the new machine. Also post an ipconfig /all from both machines.

Can you have more than one primary domain controller?Only one primary DC can be designated. According to security and reliability best practices, the server housing the primary DC should be solely dedicated to domain services.
How to add domain controller in an existing domain controller?On the Deployment configuration page, select "Add Domain controller to an existing domain" . You need to specify the name of the domain in which the new DC will be added. The "Domain controller options" page appears next. Options to make this DC a DNS server and a Global Catalog are selected by default.
Can I have 2 domain controllers on the same domain?Actually, In a larger environment, at least two domain controllers at each physical site should be DNS servers. This provides redundancy in the event that one DC goes offline unexpectedly. Note that domain-joined machines must be configured to use multiple DNS servers in order to take advantage of this.
What is an additional domain controller?What Is A Domain Controller? A Domain Controller is found in a Windows Server domain. A DC is responsible for responding to requests for security authentication. Located in a Windows NT or Microsoft Windows network, the DC server is responsible for letting hosts access various domain resources in the Windows system.
