I have set up a network between my Dell PC with XP Home OS Service pack 2and my iMac with Leopard 10.5 OS. The PC is connected directly to the server and the Mac is connected via Airport to the server. I am able to connect to the server and share files from the Dell with the Mac but I am connected only as a guest. I am unable to connect to the server as a "registered user".

Can anyone help me to do this? Do I have to do this at the PC? Apple support says I have to go to the PC and "allow remote log-in" but they can't tell me how to do this since it is not an Apple! I find it strange that I can access files on the PC from the Mac as a guest but not as a registered user????

Any help would be greatly appreciated,

Brian
