I had this problem trying to remotely access the shared folder made on another PC but Windows XP answered "You might not have permission to use the network resource. To access permissions, contact your system administrator ". Searching Google the error message above, I read several tips on the internet, but none has solved my problem which was much simpler than expected: in fact I did not understand why some file I could access it remotely, for others not, appeared the above message. The answer was that I had set only sharing the folder, but also its protection. Clicking on that folder and the sharing tab, I had made shared, so I could see it the other pc. But I could not access it because the protection was not set so as to allow it. Then clicking on the tab Security, I added the PC user who could not see that folder and tutto si รจ risolto.
