I have a network of 5 Windows XP computers. On 4 of them, I can access the shares 'remotely' from all the other computers. On the 5th, I can't access it's shares from the other 4 even though it can access their shares. My MacBook Pro and my Ubuntu 8.04 systems also can access the first 4 but not the 5th.
Computers A and B are XP Pro, C and D are XP Home, and E, the one with the problem, is XP Media Center. A, C, and D bring up a login window (which doesn't do any good) when I try to access E but B just says Accessed Denied. I can access the two web servers, IIS and Apache on machine E. Just no file shares.
File and Printer sharing is turned on on all the computers and they all haves shares with security set to allow 'Everyone' to access the shared directories. All of these computers have static IP addresses and NetBIOS is set to auto which should provide "NetBIOS over TCP". I've looked at the 'Local Security Policy' listings and can't find any difference between E and A or B. What can I do to find out exactly why access is being denied?
