title: Cannot create a new build agent with team foundation server 2012
body: <p>We recently upgraded to team foundation server 2012 update 2 and now we are getting a error when ever we try to add a new build agent.</p>
  
  <p>Error:
  TF900559: Build agent MyBuildAgent cannot serve build controller MyBuildControler. The build controller and agent must run the same version of Team Foundation Build.</p>
  
  <p>Now I have made sure that we are running the correct versions  and have even tried it with a fresh install, with update 1, and update 2 and I still receive this error message.</p>
  
  <p>I should note that this build agent was created by making a copy of another agent we have and renaming everything. </p>
  
  <p>Has any one had an issue like this? </p>
