I have a 4 node failover cluster on server 2008 R2 which has been running perfectly for many months.
Just tonight 2 of the 4 nodes failed totally with the same symptons.
The only real error event that is being logged is 1282 'Security Handshake between Joiner and Sponsor did not complete in '30' Seconds, node terminating the connection'
Nothing I do will make the nodes restart. Under the 'Network' node of the Cluster all the network connections of the 2 failed nodes are showing as unavailable. However there is no problem pinging either from or to the failed machines using either the LAN, Heartbeat, or 2 iSCSI NICs.
Google returns almost nothing about error event 1282 which is a bit of a worry.
Any help gratefully appreciated as I can't fit all my VMs on to the remaining 2 nodes and have had to shut down non critical VMs.
