satellite server zen 11.1 runinng on win 2008 r2
cloest server rules pointing to local satellite servers only except config which points to primary
all roles activated on satellites

installed 3 new stellite servers and everything was working fine after about 2-3 days no one could login
found that the authentication role was disabled on the satellite server. zcc stills shows that it is configured
tried removing the authenication role and adding back help
removed all roles and added them help
removed all roles and uninstalled the agent then reinstaleld agent and added it works.....i thought after 2-3 days same thing authentication role on all three satellite servers are disabled...

what am i missing?
