Hi Clearly this error indicates that a Global Catalog cannot be located in the AD site where you are installing the server. If you could provide some information regarding the AD and site layout that would help. Cheers, Steve

You need a Global Catalog server in the same site where you install Exchange servers. Link in error message provide you with inforamtion how to solve this. http://technet.microsoft.com/en-us/library/67aca4a0-bc3f-4f8f-8297-b13e0d347942.aspx Lasse Pettersson http://anewmessagehasarrived.blogspot.com
