Steps to replicate the issue

1. Create a windows elastic image based on the guide on this page;https://confluence.atlassian.com/display/BAMBOO041/Managing+your+elastic+image+configurations
2. Check to ensure that the new elastic agent has the Nant capability
3. Create a simple Nant task as per the screenshot below:
   
4. The build will fail with the error on security permissions. The following appears in the logs:

   log4net:ERROR XmlConfiguratorAttribute: Exception getting ConfigurationFileLocation. Must be able to resolve ConfigurationFileLocation when ConfigFile and ConfigFileExtension properties are not set.
   System.Security.SecurityException: Request for the permission of type 'System.Security.Permissions.FileIOPermission, mscorlib, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089' failed.

   The type of the first permission that failed was:

   The Zone of the assembly that failed was:
   Internet
