Postinstallation task request for a quick login
Here's an idea, but I'm not sure if it would be viable and would require a K1000 (which I'm not sure you have). Figure out a way to script a remote login, leave a breadcrumb on the newly imaged target machine, create a smart label to reference that breadcrumb (i.e. needsfirstlogin) and have the script deployed to machines in that label. Again, this all depends on the possibility of creating a script that will allow you to remotely login (possibly via vbscript, using VNC, etc). I'll research a bit when I have time to see if this is viable, but an idea at least.
Quick search on Google turned up this thread:
Remote Station Login Script
Hope something there helps!
