Yes, there as a confirmed bug which has been alievated, however, we have found with a couple of test servers (server only mode) connected to dsl the resolution problem still exists.
** This is not a bug with SME Server ** - rather a problem with reverse dns lookup through the dsl modem/router. The modem/router firware (on actiontec, 2-wire and zoom modem/routers) do not allow caching or forwarding of the routing information for the local network and will not route hostname properly.
When one types "hostname/server-manger" it will not register unless there is a hosts file created on each windows machine on the network telling of the specific host information.
By moving these test machines to a dedicated connection (adsl and cable) the problem goes away. Since setting these test machines up in server/gateway mode is next to impossible because of the phone jack connection the hosts file seems to be an adequate workaround.
