Tried every fix I can find, there has to be a way to do this. Windows XP Pro SP3 (very old and slow PC) can see the shared files on the Windows 7 Home PC (build 7600) on a wireless home network. But not the other way around. The windows 7 PC can see the XP machine but cannot get access. Everything is set as it should be, both have the same workgroup name and different computer names. I have plenty of experience fixing other problems but this one has got me well and truly stuck. Any suggestions would be most appreciated.
