Great info! Sometimes some machines are not able to connect to the internet even via a proxy. This case is similar to a standalone machine. But there is still a way! Latest versions of ppm can install a *.ppd file. type: ppm help install at the command prompt for details. Basically if all else fails, get the appropriate .ppd file to the machine via "sneaker net" or whatever and use the command line install of that .ppd file.
