Hi ! I run a small heterogeneous network of Linux boxes and Windows computer with a SuSE 8 Pro box which serves as central gateway, DNS and mail server and firewall. For a few days now, I have noticed that my users had trouble using the Windows Network Neighborhood. It would not show which other machines were available. The situation deteriorated until now, I get an error message saying that I cannot access the Neighborhood at all. The funny thing is, if I use Windows to search for a specific computer, it will find it and I can access the computer´s shared directories. I used my Linux gateway to check the other machines, they are physically available, they can be pinged and the DNS name resolution works fine. My other Linux boxes don´t seem to have any problems at all. Also, neither the Windows machines nor the Linux boxes have trouble with other network applications like mail or internet access. There have been no major hardware or configuration changes for several weeks now, thus I am sure this is no hardware problem but instead network-related. Any suggestions what my problem might be and how to solve it ? Thanks, Jörg
