I have a remote agent running on Windows Server 2012 as a Window's Service. The remote agent specifies the following directories:
Temporary directory: C:\Windows\system32\config\systemprofile\AppData\Local\Temp\
User Home: C:\Windows\system32\config\systemprofile
All build step requirements are met by the remote agent (source checkout, npm install, bower install, grunt test)
When running the grunt test task which uses Karma to test against the phantomJS browser the build fails when the remote agent fails to open a file in the temporary directory.

I have set directory permissions for Temp\ to 'all-access' for the System and admin uses.
Logging into the remote agent during a build allows me to see the temp\karma\ directory get created, but then it disappears during the failure.
