My idea is to make two script in Kaseya to quick deploy a new gateway :
Installation of the gateway :
write Knmsetup.exe and setupvars.ini
execute the KNM setup
Configuration of the Gateway :
Stop Service
Tranfert file from Kserver Agent (\KNM\gateway\#gatewayname#\gatewaydata.nxd and public\key to machine c:\KNM\
Restart KNM service
Pretty simple no ?
