SharePoint Central Admin only available via Ip, not hostname


We have a SP2007 farm for staging.
Suddenly the CA is not longer available when using the hostname, but only via the IP.


https://servername:port does not work ('page canot be displayed'


http://IP_address:port, works fine and the CA is displayed.

Whjat could be the root cause of this behaviour?

I wear a lot of hats...

"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing.

Tx for the suggestion, but it didn't help.
I suspect a problem at the IIS level (running IIS 6 on Win Serv 2003)
try and ping  does it give the local ip address?
