Now that you mention it, I do recall having a similar issue regarding saving directly to the \mount folder as you’ve encounter… I believe it came about because we’re running the console (or the deployment and imaging tools environment) with elevated privledges (administrator) and launching WSIM or other tools in the user credential space. Eventhough the user may belong in the admin group, it will not be allowed to edit directly. You can however, launch tools with the elevated privledges (like WSIM) or say like notepad, from the consoles to make direct edits in the \mount directory.
hope that helps… I’ll make a note to put a mention of that in the article.
also, regarding the NIC drivers… like gramps mentioned, they’re already in the base images, but injecting them early on is ok to… I only mention at the end of article two that you can use them to build a TEAM.
Double check that you’ve setup DHCP to reserve (or pass) the IP address specific to the NIC MAC addresses on the DX4000. I don’t go into details on this, but if you have a router/firewall setup for automatic DHCP it will get something. You may have to poke around the router logs to see what address it is getting.
