You could add a second network interface to your VM, configure it for bridge mode (NAT would probably work too, I suppose) and let it get a dynamic address from the core network. That should let the server hit the 'Net for updates (assuming the core DHCP serves out a gateway as part of the lease). Your original interface can be restricted to it’s own VLAN for imaging/deployment tasks. You could configure the server to handle DHCP/DNS for the VLAN. Deployment clients would have to be on the VLAN somehow…not sure exactly how you’d want to handle that.
As for the images, you could burn the individual images to DVD or USB or something. I’m not sure how you’d deploy them with FOG. They’re Partclone images, so perhaps Clonezilla Live? One of the developers would be able to provide a better answer.
As for the identical hardware, I would definitely sysprep the image. Even given that they’re all identical units with the same hardware, sysprep is generally a good idea. You can preinstall the drivers in Audit Mode, if you want, and they’ll be installed automagically by sysprep during deployment.
If you don’t sysprep, you’ll almost certainly run into problems with OEM licensing…although FOG can update the licenses on a per-machine basis if the data exists in the database. I’m doing something similar myself, since I’m also using OEM licensing…I use a generic non-activating key with sysprep to skip the “enter license” prompt and let FOG enter it for me post-install.
The aircard…sorry, can’t help you here. Never used one…anyone else…?
The SID…well, Microsoft will lead you to believe there will be all kinds of end-of-the-world-as-we-know-it consequences if machines do not have a unique SID. Since I use sysprep, I’ve never worried about. I do know of others (including colleagues) who never worry about it and have deployed without regenerating the SID (or using sysprep). They’ve never had issues.
Hope that helps.
