title: TFS2013: An error occurred while copying diagnostic activity logs to the drop location. Details: Internal Server Error
body: <p>I've read other articles similar to this such as <a href="https://stackoverflow.com/questions/14814641/tfs2012-access-denied-on-copying-diagnostic-activity-logs">this one</a> but I have been unable to resolve this on my TFS 2013 config.  I upgraded TFS 2012 Update 3 to TFS 2013 then moved it to another server as I needed a setup with SQL Server 2012.  I didn't have any issues with TFS 2012 but after upgrading to TFS 2013 I'm getting an error in the build system.  The builds complete as "Partially Succeeded" as the actual builds complete but I get the following error:</p>

  <p>There is a similar inquiry on Microsoft Connect <a href="http://connect.microsoft.com/VisualStudio/feedback/details/794980/after-upgrading-to-tfs-2013-preview-all-builds-now-partial-succeed-with-errors" rel="nofollow noreferrer">here</a> but I don't know how the OP resolved it.</p>
  
  <p>I've checked permissions, added full control permissions to the user that the build service runs under, NETWORK SERVICE, etc.  I added this permission to various areas, I'm not sure exactly which one needs it i.e. the build folder, the drop folder, the TFS application tier area, or what.  I don't see any helpful information in the Windows Event Logs or TFS debug log.  I'm out of ideas on how to resolve this.</p>
  
  <p>Any help would be appreciated.  And this TFS setup does not use Active Directory as I'm the sole user/developer in this config and small biz.</p>
  
  <p>Thank you</p>
  
  <p><strong>EDIT</strong></p>
  
  <p>I installed SQL 2012, Visual Studio 2013, TFS 2013 to a new server, added one solution ran a build and the exact same errors occurred.  I'll have to open a case on Microsoft Connect.</p>
