Spent an interesting couple of hours trying to network my Mac and Windows XP PC.
It's always been easy to share a drive on XP and access it from my Mac. I have also been able to share a Windows printer with the Mac using 3rd party printer drivers. The challenge has been to (a) access a folder on my Mac from the WinXP machine and also (b) to print from XP to a printer connected to my Mac.
I managed to set up Windows sharing on the Mac and log on to it from Windows - however while this is relatively secure it is a pain as I have to connect as a specific user and I can only see their folders.
Printing is a different matter - I set up print sharing on the Mac and tried to connect two different ways - from the XP machine using the IP address and then using Bonjour. Neither work at the moment - interestingly I can send a print job to the Mac printer but it never prints - even though the job shows as complete in the printer queue on the Mac.
Hmm...
