title: Access denied on TeamCity VCS update
body: <p>I have some trouble getting the VCS of teamcity work.</p>
  <p>I'm using perforce and the TC-Server should be configured correct, but when running the project I'm getting the error:</p>
  <blockquote>
  <p>[Updating sources: server side checkout...] Error while applying patch: Failed to change text file: C:\Projects\BuildSrv7... C:\Projects\BuildSrv7.. (Access denied)</p>
  </blockquote>
  <p>I checked the Settings and everybody has full rights in the directory.</p>
  <p>And idea, what to do, or how this could happen?</p>
