When trying to connect to a Windows XP machine from 10.5.2 I am unable to connect as anything other than "Guest". I have searched everywhere for the answer and it appears a lot of people have this same issue but I thought it was to be resolved as of 10.5.2 I used to be able to connect as a user to a Windows machine using username and password in Tiger, but this seems to have got broken in Leopard, as has many other things. The really bizarre thing is, it always connects to the Windows machine as a "Guest" regardless of what name and password entered. Why then even have the option to "Connect As"???
