We have installed the 2012 R2 evaluation to test our application software. Users will be accessing data in a folder on the evaluation server via a mapped drive. They will log into the SBS 2003 domain, the evaluation server is a member server of the 2003 domain. Question is will there be licensing issues on the eval server? Once we have fully tested the application we will purchase 2012 and the appropriate licenses but for testing we need to have several people accessing the application at the same time.
