Have Desktop running Vista with cable to Router and Laptop running XP wirelessly connected to Router. Have setup Networking between the two with no problems seeing/changing all files on the Laptop from the Desktop. However when trying to do same to Desktop files from Laptop I'm OK with everything EXCEPT contents of Drive C. Any approaches to that drive are instantly met with 'Not C not accessable. You may not have permission, etc. Access is Denied' I am the only user and Adminstrator on both machines. Both running Norton XP is Version 2002 SP 3 and Vista Home SP 2. Spent days on this can anyone help? Why on earth is it all so complicated, what an utter waste of time?
