Here is the batch file I use to stop and start services on ACS 4.x Windows and it works perfectly. @ECHO OFF net stop csmon >null 2>&1 net stop cslog >null 2>&1 net stop csdbsync >null 2>&1 net stop csauth >null 2>&1 net stop csadmin >null 2>&1 net stop cstacacs >null 2>&1 net stop csradius >null 2>&1 net start csauth >null 2>&1 net start csmon >null 2>&1 net start cslog >null 2>&1 net start csdbsync >null 2>&1 net start csadmin >null 2>&1 net start cstacacs >null 2>&1 net start csradius >null 2>&1 echo Complete restart finished exit 0
