Hi, About OWA problem : An OWA server (Exchange server 2003) cracked and can not startup. Can I delete this front-end server on System Manager (Exchange Server 2003) directly? If I delete this server directly, any side effects? Regards, Thomas

Are you planning on reinstalling the frontend server, if so just rebuild it. When installing exchange use setup /disasterrecovery switch. Otherwise you will have to perform the following. Delete the exchange object using adsi editfrom Configuration> Services> Microsoft Exchange>Your Org Name >Administrative Groups> YourAdminGroupName> Servers. http://support.microsoft.com/kb/833396/

Hi, I will not reinstall the frontend server. I read this article but this article is for remove Exchange Server. I find a Remove Server option when I right-click OWA server on Exchange System Manger. Does just click this option? Regards, Thomas

Yes that is correct. Remove the Exchange 2003 server from Active Directory To remove the Exchange 2003 server from Active Directory, follow these steps: 1. Click Start, point to Programs, point to Microsoft Exchange, and then click System Manager. 2. Expand Administrative Groups/Your_Administrative _Group_Name/Servers.Note In this step, Your_Administrative _Group_Name is a placeholder for the name of your administrative group. 3. Right-click the name of the Exchange 2003 server that you want to remove, click All Tasks, and then click Remove Server.This procedure will remove all references to the server in Active Directory and remove the mailbox-enabling attributes from all Active Directory users who have mailboxes on the server that you removed. If you cannot install or run Exchange System Manager, you may use the ADSI Edit snap-in to manually remove enough of the server attributes so that you can try a successful reinstallation. This method does not perform cleanups of references to the server object outside the server's own container. Microsoft does not recommend that you use this method unless you intend to immediately reinstall the server in the same administrative group, because you may have to manually remove or edit many attributes on objects throughout Active Directory. The ADSI Edit snap-in is available in Windows Support Tools.

These problems may require you to reinstall Microsoft Windows 2000 Server, Microsoft Windows Server 2003, Microsoft Exchange 2000 Server, Microsoft Exchange Server 2003, or both Windows and Exchange. Microsoft cannot guarantee that problems that occur if you incorrectly modify Active Directory object attributes can be solved. Modify these attributes at your own risk. To use the ADSI Edit snap-in to remove an Exchange 2003 server from an Exchange 2003 administrative group, follow these steps: 1. Click Start, point to Programs, point to Windows 2000 Support Tools, point to Tools, and then click ADSI Edit. 2. 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=ServersNote In this procedure, Domain_Name is a placeholder for the name of your domain, Your_Organization_Name is a placeholder for the name of your organization, and Your_Administrative_Group_Name_Or_Exchange5.5_Site_Name is a placeholder for the name of your administrative group or Exchange 5.5 site. 3. Right-click the Exchange 2003 server object, and then click Delete. 4. Click Yes in every adsiedit dialog box that prompts you to confirm the deletion.
