Our environment is 4.2 w/ patch 5. There is a central server which replicates out to 6 remote servers. Two of the remote ACS 4.2.5 servers which we have not been using yet, but which we replicate too, stopped receiving replication last night. Going to the Admin GUI, System configuration panel shows ACS "Is Currently Stopped", restarting does not work. Looking at the services control panel shows CSLog and CSRadius not running and neither can be restarted. Although CSTacacs is running, the server does not provide TACACS services. Rebooting the server does not help.
