Hi, Since you have already removed the server without uninstall you can remove the Exchange 2003 object reference with adsiedit.msc from Active Directory. Follow Remove the Exchange 2003 server from Active Directory session in below KB to remove computer object manually. http://support.microsoft.com/default.aspx/kb/833396

Hi Amit, Thanks for your reply I appreciate that...Actually i remove the server from active directory site and services... the issue now is when i try to install Exchange 2007 it refelect the error that Exchange 2003 with SP1 still exist in First Administrator Group for Exchange.Now the server is uninstalled and Removed from Active directry as domain and as computer from Site and services but still appearing in Exchange 2003 System Manager. The steps mentioned in Artical which you refered is to remove the Exchange if server exists, NOw server is Uninstalled + Deleted under Domain site and Service and from Server list but still appering in Exchange System Manager. If i will not be able to remove from the Database of Active Directry as Exchange server i will not be able to setup new Exchange 2007 SP1 on the network...Your valuable advise is requested.Thanks Regards,

Hi, To remove the Exchange 2003 server from Active Directory & ESM, follow these steps first: Click Start, point to Programs, point to Microsoft Exchange, and then click System Manager. Expand Administrative Groups/Your_Administrative _Group_Name/Servers.Right-click the name of the Exchange 2003 server that you want to remove, click All Tasks, and then click Remove Server. If you are not able to remove the Exchange server from ESM with above steps then remove with help of ADSIEdit.msc (Note: Install Windows support tools to get ADSIEdit) Go to Start, Run and write ADSIEdit.msc and hit OK button. Expand each of the following items: Configuration ContainerCN=Configuration, DC=Domain_Name,DC=comCN=ServicesCN=Microsoft Exchange CN=Your_Organization_NameCN=Administrative GroupsCN=Your_Administrative_Group_Name_Or_Exchange5.5_Site_NameCN=Servers Right-click the Exchange 2003 server object, and then click Delete. Click Yes in every adsiedit dialog box that prompts you to confirm the deletion.
