I just installed NAV2011. Now I find I cannot use Windows Explorer to browse my network. My mapped drives work; however, when I go to Microsoft Windows Network I am denied access to everything under Workgroup. This was working just fine prior to installing Norton. I'm using WindowsXP Professional and the network router is an Apple Airport as the router and a 16-port 1 GB switch. I do not have this problem on another network which uses a TrendNet router and an 8-port 1 GB switch. Anyone seen similar problems?
