I'm working on a friend's PC, and have it plugged into my home network. Every time I try to open Network Neighborhood, I get an error "Unable to browse network." I've looked for all the obvious problems, like the workgroup name, and the PC can get out through my router and DSL connection to the Internet just fine. Have Netbeui installed, too. Can someone point me to a troubleshooting procedure for this kind of problem?
