I just sucessfully got my home network to share files and printers.

Now,I have desktop running XP home and a laptop running XP Pro. I work mostly on my desktop and use my laptop for fun and occasional off site work. I have experienced system crash on my desktop twice in the last year due to lightning. I have purchased and installed a battery back up and major surge protector. Since my desktop is always on and connected to the phone lines and internet I want to backup my data files from the desktop to the laptop when systems are idle. I want the data files to be in sync so I always am working with curent data. I have set up a "shared" folder on each computer and have copied the data folders along with current data to each computer. Now I want to schedule synchronization. Can't seem to get it to work. When attempting to schedule, the only files appearing is the home page file. Any suggestions.
