Can't turn share off

[Keiser]

I bought a laptop as a second computer for home an out and about... I wanted to grab some files off the desktop computer so rather than just connecting via hardware means (like usb - not sure if you can do that though) I went into windows and turned on sharing on each disk, by right-clicking the drive in question and choosing Share. Now it wont let me turn it off... Thoughts of being hacked have come to mind but haven't seen anything suspicious going on. Checked the router - it usually tells you if something has used the network. It was able to tell me the laptop was using it - no other suspicious activity though. Firewall is turned on so the network is fairly secure - I think, but i don't wanna risk it.

If you are sure that you have disconnected client. It could be a locking issue.
SMB/CIFS has a lot of ambiguities and locks can be left on.
If you have this problem then you will have to molly it and may loose data.
Try using an Internet protocol such as SSH, HTTP or even FTP.
Not that FTP is very insecure, but not as bad as SMB/CIFS.
In Unix you use SSH to scp files. FTP is not used anymore.
