I recently installed a new router and when I started my Mac Pro the server (10.7.5) Serverwould not respond and I received an error message stating the host name has changed on my server. I can not recall what I did nut I got the server working. I had to reboot teh router again and have received the following email:

 

From: root@discussion.pharmweb.net (System Administrator)

Subject: Network change notification for discussion.pharmweb.net

Date: 26 January 2013 12:48:52 GMT

To: antony@replaced.net


The host name of discussion.pharmweb.net has changed to discussion.lan. Some services may not work correctly until they have been updated to use the new configuration.

 

I can not get the server to respond to web requests and am not sure what to change, Sharing is showing my local hostname as discussion.local

    Sounds like your server's LAN IP changed.

    Its important NOT to change your server's LAN address without going through a few steps.

    Your server is set with a 'manual' address, not DHCP, correct?

     

    Since you just replaced your router, did you re-enter your port maps?

    Without port maps, your server is inaccessible to the outside world.

    Are you sure it wasn't just the server's LAN IP that changed?

    Is it set to Manual ?

     

     

    If your server is behing a router with a NAT address, then a change in the public IP shouldn't have caused that error.  I bet your LAN IP changed and now you don't have port mapping correct. pherhaps the public IP changed also, but my money is on the LAN address.

     

    If its the LAN address, there is no point waiting for the ISP.

    Set it back to the address it used before and make sure the router provides NAT with port mapping to that address.

    Thats all in your control, not the ISP.
