Inside/outside gateway, really isn't an issue for the moment for you. But I believe Mike is referring to a gateway or router being between your Acer (the client computer you want to make an image of) and the server where you run the Ghost Console (and thus the Ghostcast Server.)
I'd take it a step simpler as Mike suggested. First, create an image, but don't store it on the local drive - don't check the image is stored on the client machine. Instead, let the image be stored on the Ghostcast Server itself. I've found this to always work better, especially at first. It avoids any potential drive space problems on the client as well - cloning a 80G hard drive that's 60G full and trying to store that image onto the remaining 20G of that same drive may be a bit tough. Obviously, depends on your usage. But again, skip that part and just stick with making the image and storing it on the GCS.
Once you have the Ghost file(s) on the GCS, see if you can just push it back to the same client. Just a quick test - it came from that machine, it should easily go back onto that machine. It's just a basic sanity test to make sure everything is working ok.
Once those two most basic operations are succesful, then you can start going down the path of storing the image on the client machine itself. Usually, I do this by having two partitions. The proverbial C: where everything is, and then a second DOS based D: partition that only stores the actual Ghost image file(s.) So when I restore my C: drive, I'm basically reading a file from the D: drive and erasing the C: drive and putting the image there. I've never been trusting of having the Ghots image file on C: and then trynig to restore C: (how do you read a file from a partition I just blew away?)
Good luck,
