I have had a simple lan at home for several years. Recently I tried Norton for a few days and quickly switched back to McAfee adding some of their new programs as well. I'm using a linksys broadband router and access point combo. All computers both wireless and cabled can see the internet. I set the notebook next to my desk top, look up the address and they were both able to ping each other but when I go into the "My Network Places" from each computer you can only see that computer in the workgroup, none of the others. I also have a network printer and they all print to it fine as well. I tried turning off all firewall software, assuming I didn't miss something that didn't make a difference. I'm sure it's something simple. They are all running Windows XP. 2 are home, one pro and one media center. Any ideas where to look next?
