I have a very simple Dynamics AX Reporting project with a dataset using the Dynamics AX data source hitting a custom query I created in the AOT. The report builds succesfully in VS2008, and when I attempt to deploy the report, an error is returned "Deployment failed unexpectedly with the message: The following components have not been installed or are not configured correctly: Reporting Extensions". The "Save to AOD" function also returns an "unknown error."
The VS2008 error shows the problem to be on the line referencing the DeployToReportsServerTask in the file: Microsoft.Dynamics.Framework.Design.Reporting.Modeling.targets

From within AX, using the Reporting servers form (Administration > Setup > Business analysis > Reporting Services > Reporting Servers), the Validate (button) returns a "success" message. Also, I can browse the reports directory on the server and my local PC through IE. My AX client configuration also launches & connects to the correct AOS.
Any ideas as to what may be the problem? Not sure what else I can check.
Thanks in advance!
