Since www.remotewebaccess.com isn't accessible this question can only be answered by the occasional member that has access to their product. Unlikely to find someone like that on a Mac forum.
That server is runinng Windows Server 2012?
What does their customer support say? And what did the system manager of that Windows server say?
