Figured DNS as follows: SBS2K multihomed Forward Zone: jedgroup.local Name Type Data _msdcs _sites _tcp _udp (same as parent folder) Start of Authority [46], viper.jedgroup.local., admin. (same as parent folder) Name Server viper.jedgroup.local. (same as parent folder) Host 192.168.1.xxx dns Alias viper.jedgroup.local. viper Host 192.168.1.xxx Wins: Reverse Name Type Data 192.168.1.XXX Pointer viper.jedgroup.local. (same as parent folder) Name Server viper.jedgroup.local. (same as parent folder) Start of Authority [27], viper.jedgroup.local., admin.jedgroup.local. nslookup correctly identifies both adapter's IP addresses with the internal being viper.jedgroup.local and the external being jedgroup.com The workstations are attached through a dumb switch on the internal adapter. When we try to ping the "server" from the workstation it finds it (delayed). When we try to ping jedgroup.com, it times out. Also the workstations report "can't find dns server" or network path. Workstations are registered on AD and adapters have only the dns of 192.168.1XXX. Wins only carries single address (internal) and is not (like MS client, sharing) available on the external NIC. What do we have to open? EL
