The only thing I did which the server worked before and couple of minutes after that was to recreate the account that my hostname is based on that domain. thats it.
but now when I check the IP in browser it does not resolve. none of the IP addresses.
I've disabled the internal IP address.
restarted the server.
typed the command you provided.
now I can ping the server from local net work by public IP addresses. but when I use a vpn connection from outside world. I can not see anything. I asked couple of friends from UK and Middle East to check and they can not either ping or see anything.
