At home I have a fileserver which is running Windows XP Pro. There are various SMB shares set up on it which can be accessed fine from within the network.
Recently there has been the need to access the files on the fileserver from outside the network. The data stored on the fileserver is sensitive, so this must be done securely; it feels like opening SMB over the internet would cause problems here.
SFTP is not an appropriate solution as the files to which access is required may be worked on concurrently from within and outside the network so the potential for problems there is clear.
Remote desktop or similar is also not appropriate as the remote computer has an application which utilises the data I wish to share. This application cannot be installed on the fileserver.
Ideally, I need a way to map the fileshare as a network drive from outside the network.
Can anyone suggest any directions in which I could look? I do have a copy of 2008 Server which I could upgrade the fileserver to if it would help, but I'd rather not do so given that it has been running stably for years and it would require considerable work to get everything re-configured.
