We have been running ARR for over a year now without any problems. Recently we have had a lot of increased load on the servers due to more clients. The load balancing aspect is currently sending most requests only to one server while the other one almost idles.
Our idea is to switch client affinity off, but this causes the authentication to fail. The web site just goes back to the login screen without any errors.
I can confirm that both the machine key and application ID is the same across all servers. A strange thing as well is that as soon as we switch off client affinity a request goes to each of the content servers instead of just one. This happens from both chrome and Internet Explorer.
Any help or suggestions would be appreciated.
