Issue with generated file in VS2010 build

We are currently building a RIA Dataservices project.  Part of the output is a generated file that the client depends on.  When this is build with VS2010 it generates fine.  When I build is directly with MSBuild locally(nothing more than MSBuild.exe and solution) it builds and generates fine.  However, when I attempt this within TeamCity, the file is never generated and the build fails.  Is there anyway around this or am I don't something wrong?  I am performing this build on an agent using Agent side checkouts.  Any help is appreciated.

Thanks,
Bryan
