I need help with my wireless network

Good Morning,

I am literally the new kid on the block. I just joined about five minutes ago.

I have two Toshiba laptops on my wireless network. We have one set up as the master, and one is set up as the slave. I use A windows database program for inventory control. I thought we had it set up so that only changes could be made to the master, and then we could refer to the slave in a remote location for updates. I noticed the other day I was able to make changes to the slave computer and save them. My real problem is: I can update the database on the master just fine, but I can not get the slave computer to access the updated information. I've rebooted it and all that comes up is old data. Any suggestions?

Thanks
