Whats wrong and what can I do in this situation?Thanks for any help.

Did you ever find a solution for this (Microsoft.Exchange.Data.Directory.SystemConfiguration.ResourceBookingConfig) error. I am having the same problem, and have no idea.

Did you follow the articles mentioned above? Did you run setuo from a UNC path, sometimes it works better if you copy files to a local folder and run from there.

[ERROR] The operation could not be performed because the object 'Microsoft.Exchange.Data.Directory.SystemConfiguration.ResourceBookingConfig' could not be found on dc1.mydomain.Done.http://support.microsoft.com/kb/949526/en-us
