I have a Two Server Deployment that was working fine with FMS14.
Master --> Windows Server 2008 R2 Enterprise
Worker --> Windows Server 2012 Datacenter.
I updated the Worker machine to Windows Server 2012 R2 Datacenter
No updates were applied to Master.
Installed FileMaker Server 15 on both the Worker and Master machines.
During Deployment, I can not see the Worker Machine to attach it to the Master.
As a work around, I can (and did) do a single machine deployment successfully)
I have a ticket in with IT to update the Master to 2012 R2 Datacenter. Will this help?
