WORKAROUND

Warning If you use the ADSI Edit snap-in, the LDP utility, or any other LDAP version 3 client, and you incorrectly modify the attributes of Active Directory objects, you can cause serious problems. 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 work around this issue:

1. On the server where you want to install Exchange 2003, run Exchange 2003 Setup.
2. When the Component Selection page of the Microsoft Exchange Installation Wizard appears on your screen, go to step 3.
3. On the domain controller, use ADSI Edit to change the value of the OperatingSystemServicePack attribute of the domain controller from SERVICE PACK 3 to Service Pack 3. To do so:
   1. Start ADSI Edit.
   2. Expand Domain [ServerName.Domain.com].
   3. Expand DC=Domain,DC=com, and then expand OU=Domain Controllers.
   4. Right-click the appropriate domain controller, and then click Properties.
   5. Click the Attributes tab.
   6. In the Select which properties to view box, click Both.
   7. In the Select a property to view box, click OperatingSystemServicePack.
   8. In the Edit Attribute box, type Service Pack 3, click Set, and then click OK.
   9. Quit ADSI Edit.
4. On the server where you are installing Exchange 2003, specify the action that you want to perform in the Action column of the Component Selection page of the Microsoft Exchange Installation Wizard.
5. Follow the instructions on the remaining pages of the wizard to install Exchange 2003 on the server.
