Any update on this. To summarize, when opening the Monitoring service (installed on a seperate server to the BES, with the BMSStore DB on the same server as the Monitoring Service) I get a blank screen before even being able to login. SNMP doesn't come into play at this stage. My SNMP is working fine, but I can't get into the Monitoring Service to configure it the service to accept SNMP packets.
Better to light a candle than to curse the darkness.
