Hi!
Check what dependencies you have in NetXMS Core service. Looks like one of this services cannot start. Try to start each dependency service manually and see what happens.
You can have web frontend for NetXMS. It is installed as separate package. For Windows it is https://www.netxms.org/download/webui/netxms-webui-1.2.0.exe (32 bit) or https://www.netxms.org/download/webui/netxms-webui-1.2.0-x64.exe (64 bit).
Best regards,
Victor
