BT2700HGV modifying default Domanin name

[selectt]

I recently upgraded my ADSL connection and purchased 5 IP addresses.

i declared various machines on the network, programmed them as DHCP and obtatined a local ip address from the router.

i then mapped a fixed ip address to the local address, reset the device and things were working ok.

one of the devices is my Alcatel-Lucent communicaiton server. Again i programed this as DHCP and assigned a fixed ip address and then reset. Again no problem.

once issues is causing me a problem though. My Alcatel-Lucent communication server has a programmed domain of ABC.net

All my email and web is housed on the server an relies on this domain. Since i allocated it a fixed IP address my servers domain name has changed to 2wire.gateway.net

this stops email being received. If i manually change it back on my server to ABC.net everything works ok but randomly throught the day it reverts back to 2wire.gateway.net

Obviously this is happening because iam getting my ip address from the router, the only way is DHCP, can i stop this happening ?

i have modified the routers domain name to ABC.net but it keeps on reverting back to 2wire.gateway.net

help please ??

The local domain name of gateway.2wire.net should only be getting used by the router itself, the DNS Suffix will be set to gateway.2wire.net how ever. You should have a domain already mapped to the public IP of your server, you can see this in Settings> Broadband> DNS Resolution. If for some reason your server is showing with a different DNS name, then you can additionally add abc.net to your servers IP address, but generally the DNS name of devices are set to whatever the computer name has been set to on the device itself.
