I came across this http://support.microsoft.com/kb/810881 which describes my problem but doesnt help me,
To resolve this issue, you must turn off Simple File Sharing, and then take ownership of the folder: 1. Turn off Simple File Sharing: a. Click Start, and then click My Computer.
b. On the Tools menu, click Folder Options, and then click the View tab.
c. Under Advanced Settings, click to clear the Use simple file sharing (Recommended) check box, and then click OK.
on the computer which im having this problem the Use simple file sharing check box isnt there, on all my other computers it is, but on this one it isnt.
btw im running windows xp sp2.
