Question about scripted installations and swapping hard drives

In our office, instead of imaging, we do scripted installations from the server - so each PC gets a fresh installation of the OS and all programs, but they are still identical. Quite nice.

The problem is that the "higher-ups" in the building recently started a "port lockdown" procedure. Basically that means that every network drop is associated with one IP address and one MAC address. Any deviation and the port locks up. I'm assuming that this isn't totally off-the-wall and that some of you know what I mean. So I can assign one of our new PCs to an open port, but then I can't keep switching them out as I script them.

Here's my idea - if one new PC stays attached to the network like that, would it be cool to just swap hard drives? After each installation, pop out the HDD and put it in another of the new PCs. Assuming that there is no deviation in hardware from one PC to another, is there any problem that could arise from that?

I hope this all made sense.

It should work since MAC addresses are burned into the ROM of a NIC card. Personally I would look into ghosting since it's less hassles. Unless you're still usig hubs, which doesn't sound like it?

What's the point of the port lock down? Did you have a problem with people bringing in laptops from home? This would be a management nightmare if people moved to new desks.

Well, I'm part of the IT staff for the department on the 10th floor of a 17-floor building. So the main "backbone" of the building's network (switches and such) are out of my control. As for "Why?" - your guess is as good as mine!

I'm sure that the MAC address/lockdown wouldn't be an issue. I'm just wondering if switching hard drives from one machine to another identical machine could cause a problem. If anything was different (motherboard, for example) it could be a disaster. But in this case I'm safe, right?

Yeah, I've Ghosted before and I like it. But I tell you, scripted installations are great when you don't have these kinds of hassles. You just boot to the network with a floppy, whch automatically maps a drive to the server. Start a batch file and it runs completely unattended from there. A "fresh" install of everything in one fell swoop.

I've done this with Norton Ghost Enterprise. Keep the image on a server, boot over the network with a floppy and image the PC. Person I worked for at the time said he would ghost 20 machines at a time in his old job. With a Cisco switch it takes about 30 minutes to ghost 20 machines with a 1.5GB image.

Switching HD's won't do anything. MAC addresses are burned in the network card's ROM. It's a 2 part address. First the manufacturer and then a unique ID.
