Should I start SNMP service from services to monitor alarms from IPCC?
If yes - what should I do ?
Because when I manualy start SNMP service - it simultaneously stops
On the UCCE servers, installing Cisco hardening will disable the Windows SNMP agent. Do not enable it. Installing the instance will install the Cisco SNMP agent. This is the one to use - don't fiddle with the Windows one.
I bet the Cisco one is running perfectly well, and you are playing with the Windows one. You try to start it but there is already an SNMP agent, so it exits.
