Wow, I just re-read my post... wasn't all that clear. I want to access the shares on the laptop from the work machine, not the other way around (accessing domain resources from the laptop). You could get it done either way, I suppose, but wanted to see if it could be done... I'm going to try some of the suggestions on here from people who interpreted it the way I meant it and update.
Oh, and yeah... using that option in remote desktop worked, but it'd be nice to not need to use RD to transfer stuff.
