Hi Scottcummins,
Hi,
Unfortunately, the available information is not enough to have a clear view of the occurred behavior. Could you provide more information about your environment. For example,
the exact text of any error messages that you received that are associated with this problem? 
The server version of the problem on, when you experience this issue what are you trying to do, when this problem occurs the system log record information, screenshots is the best information.
If you are using server 2012r2 cluster please install the Recommended hotfixes and updates for Windows Server 2012 R2-based failover clusters updates.
