Hi
I am currently in the process of implementing NLB in Windows 2012 R2 but am experiecing a few issues.
I have two windows 2012R2 machines that are being used as web application proxies for ADFS. When I add the first server to the cluster it work perfectly fine but after 30 minutes or so you are no longer able to ping the cluster IP and it no longer passes any requests over to the federation servers.
I do a ping -t and it works great but then falls over. Any ideas?
