I've really got very little idea what I'm doing here, so please forgive me if I am missing anything painfully obvious.
As the nerd of last resort for a friend, I've recently found myself in the position of performing the administration tasks on a Windows Server 2003 server being used in a business. Its a Windows 2003 Server behind a consumer DLink DSL Modem/NAT Router with a Dynamic DNS setup. It is used by 3 Laptops for file storage (in the office) and file storage and access via Remote Desktop (on site).
They have requested I set up a method for them to access their files in a method beyond a remote copy of Office when they're on site. I've never done this before, and I've got no idea how to even start. Loosely, I thought that I should try setting up a VPN, though I'm not even sure that this is the best way, or would do the trick. My problems with VPN are compounded by Server's apparent need of using 2 network connections - 1 for the network and 1 for internet.
This may be overkill. Essentially, I need a solution that can give access to files on a 2003 Server, like they're in a folder on the machine (through My Network Places, or a shortcut to the folder on the desktop) whilst on the internet, when the Server isn't functioning as the DHCP Server/NAT router.
Has anybody got any clue on how to solve this? Network administration is really very new to me.
