Cluster freeze when node left cluster

PAS cluster might freeze for about 1 minute when a node leaves the cluster, due to the default behavior of the Windows Firewall.

This problem does only seem to occur if the Windows Firewall "Domain profile" is enabled.

This feature is called "stealth mode" and is enabled by default.

How to disable stealth mode

  1. Import the attached registry file 
  2. Reboot the Windows server
