I recently got a professional version of Win XP SP2 and installed it on my desktop computer. My laptop is running Win XP SP2 also. When I share a folder from my desktop without "Simple File Sharing" on, it always gives me the "... is not accessible. You do not have permission to accesses this..." error. So ok, I enable simple file sharing and it works... until I access some sub folders, then I get the same message. I am administrator on both my PCs, I have never had this problem until SP2. All I want to freaking do is transfer files but I can't even do that... SO annoying. Does anyone have any idea what is going on or how to fix it?
