SYMPTOMS
When you run Microsoft Exchange Server 2003 Setup, and you try to specify an action in the Action column on the Component Selection page of the Microsoft Exchange Installation Wizard, you may receive the following error message:

Setup encountered an error while checking prerequisites for the component &quot;Microsoft Exchange&quot;:

0XC007FFFF (65536): An unknown error has occurred.

Additionally, the Exchange Setup Progress.log file contains entries that are similar to the following:  [Time] ScVerifyOSVersionInfo: osvi.dwMajorVersion = 5 [Time] ScVerifyOSVersionInfo: osvi.dwMinorVersion = 0 [Time] ScVerifyOSVersionInfo: osvi.dwBuildNumber = 2195 [Time] ScVerifyOSVersionInfo: osvi.dwPlatformId = 2 [Time] ScVerifyOSVersionInfo: osvi.szCSDVersion = 'SERVICE PACK 3' [Time] ScVerifyOSVersionInfo: osvi.wServicePackMajor = 3 [Time] ScVerifyOSVersionInfo: osvi.wServicePackMinor = 0 [08:31:14] ScVerifyOSVersionInfo: osvi.wSuiteMask = 0X0112 [Time] ScVerifyOSVersionInfo: osvi.wProductType = 3



CAUSE
This issue occurs if both the following conditions are true:
 * The domain controller in your site is running Microsoft Windows 2000 Server Service Pack 3 (SP3).

-and-
 * The value of the OperatingSystemServicePack attribute of the domain controller uses all uppercase letters and is set to SERVICE PACK 3.

Exchange 2003 Setup queries the domain controller in the site for the version of the service pack that is installed on the domain controller. If the domain controller is running Windows 2000 SP3, Exchange 2003 Setup expects the value of the OperatingSystemServicePack attribute to be set to Service Pack 3. You receive the symptoms that the &quot;Symptoms&quot; section of this article describes if the value of the OperatingSystemServicePack attribute is set to SERVICE PACK 3 instead of Service Pack 3.



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:  On the server where you want to install Exchange 2003, run Exchange 2003 Setup. When the Component Selection page of the Microsoft Exchange Installation Wizard appears on your screen, go to step 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:  Start ADSI Edit. Expand ''' [. .com]'''. Expand DC= ,DC=com, and then expand OU=Domain Controllers.</li> Right-click the appropriate domain controller, and then click Properties.</li> Click the Attributes tab.</li> In the Select which properties to view box, click Both.</li> In the Select a property to view box, click OperatingSystemServicePack.</li> In the Edit Attribute box, type Service Pack 3, click Set, and then click OK.</li> Quit ADSI Edit.</li></ol> </li> 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.</li> Follow the instructions on the remaining pages of the wizard to install Exchange 2003 on the server.</li></ol>
