I have 2 ADFS (3.0) virtual servers (server 2012 R2 on VMware) in an NLB cluster (setup for Office 365 initially) and want to be able to use the SAML to connect to a couple of Linux servers in the same network to allow SSO to the Linux boxes.
It was working then stopped and now the primary FS server (FS1) cannot ping either Linux box or one of our WS08R2 file and print servers. It can ping all other servers in the same network.
I tried to get a packet capture with MS NetMon 3.4 but it only picked up the successful ping requests.
Firewall is disabled but that made no difference.
NLB cluster configured in Unicast mode as I found Office 365 and another outside service didn't want to work using Multicast or IGMP Multicast.
The really bizarre thing is the secondary FS vm can ping the other boxes even with "ping server -S clusteraddress"
Any suggestions as to where to look to track this down will be most welcome.
Cheers
David
