What is it doing? Just installing GM and then going straight to the login screen?
Have you tried recreating the setup files? It sounds as if something has gone wrong with the process and the install doesnt know its supposed to be a remote install.
I should add that this isn't a single install file like JOE.EXE. Due to size it creates the separate files. Either way the /v switch isn't being honored in the batch file. I've messed around with it long enough that I'm going to just do an install and transfer sets to get it done.
