I am using a dial on demand modem and when I logon to a W2k machine the modem fires up. In theory (I think) this should not happen I have the libnss_wins.so.2 file in the right place and my nsswitch file is setup to hosts = files wins dns. The wins server is working and resolves the name to ip address but why does it then search in dns. If I take the dns away all is fine but I need that for outgoing serveice. I am pretty sure it is working and not just using broadcasts. Any help is appreciated David Mulcahy
