The DHCP auto upgrade is really useful but would it not be easier to just bundle the changes for the ICA hot keys and send them to the device?
Pull a config with Rapport, open up the settings.reg and search until you find the hot keys. edit out all the other information except the regfile headers and the hot keys. You can then use the bundle32.exe tool from Wyse to put the setting into a .bin
Sounds complex but it should not be that hard…
Also SNMP support will disappear from the devices at some stage so it will be useful not to use SNMP to do this. I would recommend sending reg files as bin’s rather than directly manipulating the registry with the Rapport agent anyway,
