Hello James,
welcome to the Polycom Community.
It is always useful to include the currently used software version as issues experienced may already be addressed in a newer release.
This also allows yourself and others to check against current software release notes.
In addition please be aware that the HDX is only LYNC qualified and requires a RTV license on the HDX.
You should simply follow the Polycom® Unified Communications Deployment Guide for Microsoft® Environments
=> here <= and please be aware that you must enable NTLM on your Microsoft Lync or Office Communications Server.
Please ensure to provide some feedback if this reply has helped you so other users can profit from your experience.
Best Regards
Steffen Baier
Polycom Global Services
