The Exchange Server 2007 installation fails during the PrepareSchema

The operation could not be performed because the object ‘Microsoft.Exchange.Data.Directory.SystemConfiguration.ResourceBookingConfig’ could not be found <Domain_Controller_Name>.

This problem occurs because the Resource Schema object under Global Settings in Active Directory directory service is missing.

To solve this problem you have to manually create it.

1- Click Start, click Run, type adsiedit.msc, and then press ENTER.

2- Locate the following location:

DC=<Domain>, DC=<suffix>
CN=Global Settings, CN=<Organization Name>, CN=Microsoft Exchange, CN=Services, CN=Configuration,

3- Right-click CN=Global Settings, click New Object and then click Next.

4- Click msExchResourcesChema, and then click Next.

5- In the Value field, type Resource Schema.

6- Right-click the Resource Schema object, click Properties, and then click msExchVersion.

7- Set the value of the msExchVersion attribute to 4535486012416.

8- Retry Setup /prepareSchema It should work fine
